A linear data structure that adds and removes elements using a first in first out (FIFO) rule, so the items added will be removed in the same order they were inserted in. Data Structures (DS) tutorial provides basic and advanced concepts of Data Structure. Data-backed responses to each of these scenarios hold tremendous value for a given department within a healthcare organization. Array, Linked List, stack and queue, all of these are linear data structures. Non-Linear Structures: Matrix Methods of Analysis and Design by Computers presents the use of matrix methods of structural analysis suitable for computers. Since, we already have lots of problems to deal with, it completely depends on the requirement of our problem which data structure to select. This course Data Structures and Algorithms in python includes explanation of various data structures with coding examples, provided with detail explanation of code side by side with concept building.

Hence, such a traversal follows the ' neighbour-first' principle by considering the following: - No vertex is visited more than once - Only those vertices that can be reached are visited Importantly here, we make use of the Queue data structure. The insert method would require linear time. Linear search is the process of finding a value in a list of values using sequential order of comparision Linear Search Algorithm - Data Structures The perfect place for easy learning. It can perform 1. DeQueue is a data structure in which elements may be added to or deleted from the front or the rear. Key Differences Between Linear and Non-linear Data Structure In the linear data structure, the data is organized in a linear order in which elements are linked The traversing of data in the linear data structure is easy as it can make all Data elements are adjacently attached in the linear. Array is a data structure used to store homogeneous elements at contiguous locations. A data structure is said to be linear if the elements form a sequence, for example Array, Linked list, queue etc. In case of linear arrays, the declaration statements tell how many cells are needed to store the array. Stack, Queue and Linked List are the types of linear data structure. What are the major data structures used in the following areas : RDBMS, Network data model & Hierarchical data model. are all data structures. Which of the following data structure is non-linear type? A) Strings. "The quadtree and related hierarchical data structures," ACM Computer Surveys 16(2):187-260. Data Structures and Algorithms - Arrays - Array is a container which can hold a fix number of items and these items should be of the same type. This "Data Structures and Algorithms in C#" tutorial will help you develop a strong background in Data Structures and Algorithms. Operations on linear Data Structures • Traversal: Visit every part of the. A linear data structure that adds and removes elements using a first in first out (FIFO) rule, so the items added will be removed in the same order they were inserted in. The Non Linear Data Structures are complex data structures which can prove to be tricky to an extent. A stack is a basic linear data structure: a logical entity pictured as a physical stack or pile of objects. PROGRAM 1 –Linear Data Structure Implementation Release date: September 19th, 2016, Due date: October 3rd, 2016 5% Grade Points Given the starting point in a maze, you are to find and mark a path out of the maze which is represented by a 30x30 array of 1s (representing hedges) and 0s (representing the foot-paths). Linear Data Structure: Those data structures where the data elements are organised in some sequence is called linear data structure. However, this doesn't show a list being useful in anyway. This course is about data structures and algorithms. In this searching technique you need to check every elements one by one until desired element found. In computer science, an abstract data type (ADT) is a mathematical model for a certain class of data structures that have similar behavior; or for certain data types of one or more programming languages that have similar semantics. Explanation are given for understanding. A linear data structure is a type of data structure that arranges the data items in an orderly manner where the elements are attached adjacently while a nonlinear data structure is a type of data structure that arranges data in sorted order, creating a relationship among the data elements. Our 1000+ "Data Structure - Part 1" (along with 1000+ "Data Structures & Algorithms - Part 2") questions and answers focuses on all areas of Data Structure covering 200+ topics in Data Structure. The major difference between Array and Linked list regards to their structure. Linear Data structures are kind of data structure that has homogeneous elements. In this tutorial you know the difference between Linear and Non-Linear Data Structure in C. A typical illustration of random access is a book - each page of the book can be open independently of others. Abstract Data Structure "List" Let’s now give a more strict definition of the structure list: List is a linear data structure, which contains a sequence of elements. data structure in hindi:-data structure किसी कंप्यूटर सिस्टम में डेटा को स्टोर तथा व्यवस्थित(organise) करने का एक तरीका होता है। जिससे कि हम डेटा का आसानी से इस्तेमाल कर सकें।. Breadth-First Traversal: Traverse all the vertices starting from a given ' start vertex '. Overview of Data Structures | Set 1 (Linear Data Structures) 1. - Outline the algorithms for creating, accessing and modifying each data structure - Analyze the running time of these operations. The Linear Data Structures are comparatively simpler and provide a certain ease of working with. data structure in hindi:-data structure किसी कंप्यूटर सिस्टम में डेटा को स्टोर तथा व्यवस्थित(organise) करने का एक तरीका होता है। जिससे कि हम डेटा का आसानी से इस्तेमाल कर सकें।. Every item is checked and if a match is found then that particular item is returned, otherwise the search continues till the end of the data collection. Based on the organizing method of data structure, data structures are divided into two types. In this searching technique you need to check every elements one by one until desired element found. Tree and graph structures. For example, one common data structure is the list or array , which is an ordered sequence of values. Though many candidates may never encounter data structures in day-to-day programming, showing a mastery of these concepts can help you rock your next interview—and add to your coding toolkit. On the other hand, a non-linear data structure is a structure wherein each data element can connect to more than two adjacent data elements. Each node contains a data part and a pointer part(a pointer to the next data in the list) link or node is object of a class. In Section 2, we examine data structures such as sets and strings that can be represented by lists, then look at a special data structure called a heap. One of the most effective representations is a hash table. Deleting 5. Example is tree. It has two main operations enqueue and dequeue. Array, Stack, Queue, Linked List. If nothing else, all of the above should pound home the idea that if you want to become a software engineer, algorithms and data structures will pave (and maybe even pay) the way for you. And non-linear is of course not linear :) => when you do a search in a non-linear structure is generally faster than linear structure. A data structure determines the way data is stored, and organized in your computer. Linear probing is a scheme in computer programming for resolving hash collisions of values of hash functions by sequentially searching the hash table for a free location. Each node or item may be connected with two or more other nodes or items in a non-linear arrangement. Efficient memory utilization is experienced while working with the non linear data. Since, we already have lots of problems to deal with, it completely depends on the requirement of our problem which data structure to select. Pros:-Arrays size is fixed. The first element stored in the stack is last removed out and the element last stored is first removed out. Only finite amount of elements can be inserted into a linear queue. A linked list is a linear data structure consisting of a set of nodes, where each one except the last one. Linear probing is used for resolving the collisions in hash table, data structures for maintaining a collection of key-value pairs. Steven Lindell [email protected] When authors use linear narratives, the order in which events are portrayed corresponds to the order in which they occur. Some examples of data structures are: linear. Arrays, linked lists, trees, graphs, etc. Apart from computer science, they are used broadly in the fields of Geography, Chemistry & Engineering Sciences. Operations on linear Data Structures • Traversal: Visit every part of the. The data set I used as an example in this blog is small enough to fit into a reasonable amount of space using a variety of data structures, trie's included. Linear data structures organize their data elements in a linear fashion, where each data element attaches one after the other. Also, we'll cover the central concepts and typical applications. The cryo-EM structure of the Escherichia coli 70S-PHZ complex reveals that the drug interacts with the 23S rRNA and uL4/uL22 proteins and obstructs ribosomal exit tunnel in a way that is distinct. Data Structures & Algorithms ! 4. This website uses cookies to ensure you get the best experience on our website. Whereas, a tree data structure , specifically B view the full answer. In computer science, an abstract data type (ADT) is a mathematical model for a certain class of data structures that have similar behavior; or for certain data types of one or more programming languages that have similar semantics. Aggregate parent (I am a part of or used in ) linear probing sort. We will move past the basics of procedural programming and explore how we can use the Python built-in data structures such as lists, dictionaries, and tuples to perform increasingly complex data analysis. Instead of items being placed at indices, however, they are connected through a chain of references, with each item containing a reference to the next item. A base linear mixed model was fitted to explore the functional form of G:F relative to Trp:Lys ratios and assess model assumptions. It can perform 1. A sparse, linear octree data structure. Two other examples are multidimensional arrays and graphs. A new element in a queue can come only at the end, not anywhere else. Depending on the way the data is accessed data structures are divided into linear and non linear datatypes. * Linear Data Structure. To insert an element 47 in a linear queue, then rear value of the linear queue will be incremented by one to place a value 47 in its last position. Linear Search and Binary Search Algorithms with Examples On December 20, 2016 January 4, 2017 By Kaushik Vaghani In Data Structure , Searching Algorithms Introduction to Searching. : Arrays, Records etc. Linear data structure: A linear data structure traverses the data elements sequentially, in which only one data element can directly be reached. These nodes have been scrambled up and placed in a MARIE program as shown. Whenever data exists it must have some kind of data structure in order to be stored in a computer. Linked lists, stacks, queues, etc are linear data types. Trees—binary search trees, red-black trees, B-trees. Overview of Data Structures | Set 1 (Linear Data Structures) 1. Examples of Non-linear Data Structure are Tree and Graph. Linear(Sequential) Queue Operations This is a linear list DATA STRUCTURE used to represent a linear list and permits deletion to be pe Data Structure - [Linear (Sequential) Linked List] Linked List Operations A linked list is defined as a collection of nodes. Linear Queues in Data Structures Linear Queues. “A data structures in which element are added & removed from only one end , “A last in first out structure. So that a given data item has the possibility to reach one-or-more data items. The Data structure is said to be Non-Linear Data Structures if it's elements do not form a sequence or a linear series but form a hierarchical format. A linear data structure that adds and removes elements using a first in first out (FIFO) rule, so the items added will be removed in the same order they were inserted in. 9/11/2008 31 Classification of Data Structure Linear and Non-Linear: In linear data structure, the data items are arranged in linear sequence. More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data. The prior knowledge of number of elements in the linear array is necessary. "Discrete Math" is not the name of a branch of mathematics, like number theory, algebra, calculus, etc. • Structure means a set of rules that holds the data together. Arrays also can be used to store linear data. Linear data structure and non-linear data structure comes under non-primitive data structure. About; Algorithms; we have visualizations for the following data structures and algorithms: Binary and Linear Search (of sorted. – Review the basic linear data structures – Demonstrate how each can be defined as an Abstract Data Type (ADT) – Demonstrate how each of these ADTs can be specified as a Java interface. So, far in this series, we have talked about what we can call linear data structures. This set of multiple choice question on data structure includes solved MCQ questions about different levels of implementation of data structure, tree and binary search tree. In linear data structure data is to arrange no specific order and data is arranged adjacently whereas in non-linear data structure data is arranged in a specific order and there is a relation between data. But compare with the Linked List, Arrays have some limitations. Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. COEN 279/AMTH 377 Design and Analysis of Algorithms Department of Computer Engineering Santa Clara University. If the underlying data structure is based on a tree or trie, then a reference to the container can. These topics are chosen from a collection of most authoritative and best reference books on Data Structure. AGC Lighting's 90W Led Linear Warehouse Light are made of selected materials, which ensures its high quality. You will learn how to implement data structures to store and modify sets of objects and mappings from one type of objects to another one. Efficient memory utilization is experienced while working with the non linear data. The C# data structure, ArrayList, is a dynamic array. Update: This operation changes or modifies the data in the data structure and it is an important property in selection operation. The simplest type of data structure is a linear array. Various types of dynamic storage are employed by system and applications software. data structure. are all data structures. Here i am trying to tell you almost everything about Data Structure and its applications. A data structure determines the way data is stored, and organized in your computer. Traversal : Visit each and every element of the structure. The only significant difference between Stack and Queue is that instead of using the LIFO method, Queue implements the FIFO method, which is short for First in First Out. Given a stack, the accessible element of the stack is called the top element. 800 East 96th Street, Indianapolis, Indiana 46240 Data Structures & Algorithms in Java Second Edition Robert Lafore 00 0672324539 fm 8/28/03 9:35 AM Page i. The Linear Data Structures are comparatively simpler and provide a certain ease of working with. Each data item has at most one predecessor and at most one successor. : Arrays, Records etc. Data elements are traversed one after the other and only one element can be directly reached while traversing. Example of linear data structures include Arrays, Stacks, Queues and linked lists. A non-linear data structure is a data structure in which a data item is connected to several other data items. Linear are those in which data is stored in a sequential manner, and can be accessed in a sequence too. Sorting algorithms—insertion sort, merge sort, heapsort, quicksort. Linear data structure: A linear data structure traverses the data elements sequentially, in which only one data element can directly be reached. are all data structures. It covers everything from linked lists, stacks, trees, graphs and of course a multitude of sorting algorithms for your daily data structure need. There are several common data structures: arrays, linked lists, queues, stacks, binary trees, hash tables, etc. The textbook Algorithms, 4th Edition by Robert Sedgewick and Kevin Wayne surveys the most important algorithms and data structures in use today. The Non Linear Data Structures are complex data structures which can prove to be tricky to an extent. Interpolation Search. Linear Data Structures 2 Linear Data Structures Describe how arrays are implemented in Java. Each of the other elements in the linear data structure has a predecessor and a successor. This course is about data structures and algorithms. You will start by learning the basics of data structures. Data Structures tells you what way the data as to store in computer memory and how to. Sc Colleges. You will see that naive implementations either consume huge amount of memory or are slow, and then you will learn to implement hash tables that use linear memory and work in O(1) on average!. Data Structures and Algorithms - Arrays - Array is a container which can hold a fix number of items and these items should be of the same type. The difference between linear and nonlinear data structure is that in linear data structures, the organization of data elements are sequential while in nonlinear data structures, the organization of data elements is not sequential. Structure for an element of the linked list A linked list contains a list of data The Data can be anything: number, character, array, structure etc structure, etc. A non-linear data structure is a data structure in which a data item is connected to several other data items.

You will master lists, stacks, and queues, and learn about how computer memory. In this tutorial, we will see binary search algorithm In data structure. Example is tree. g of complex data structure. Non Linear are – Tree, Graph. These do not provide us with efficient memory utilization. Calculate and print the sum and average of the elements of the sequence. Download our App and read it whenever you feel like. This example certainly clarifies the idea of non-linear data structure. * Linear Data Structure. What goes wrong if we try to keep all the items at the front of a partially-filled array (so that data[0] is always the front). Finally, we'll cover a series of algorithms for regular online orthogonal 2D range searching, including an impressive linear-space cache-oblivious data structure for 2-sided (quarterplane) range queries, as well as the trick for shaving off a log log factor of space from a regular 4-sided range search data structure. University of Iowa 22C:21 Data Structures. NET Dictionary , and is a key-value structure, where a value is accessed by using a key string. Here are different types of data structures:-. Operations on a vector offer the same big O as their counterparts on an array. Non Linear Data Structures: The data structure where data items are not organized sequentially is called non linear data structure. Apart from computer science, they are used broadly in the fields of Geography, Chemistry & Engineering Sciences. Data structures are classified as linear and non-primitive data structure. There are benefits to using a linked list over an array, and benefits for using an array over a linked list. Increasing the size and dimensions of the data set could cause the space requirements to jump significantly. , constant time, independent of the total number of integers stored). D) Hierarchy. I know what linear and nonlinear data structures is ,but could someone explain me in 2-3 phrases what the differences is? It would like to have the differences about the two of them and not the. In programming languages, an array is a way of storing several items (such as integers). As an application, we prove that the set of vectors obtained from rank one binary matrices is rigid with parameters matching the known results for explicit sets. There are many different data structures which are generally used. Definition: A binary tree is a finite set of nodes which is either empty or consists of a root and two disjoint binary trees called the left subtree and the right subtree. I am very grateful you made this choice. Under the hood, an ArrayList is an array whose size is doubled every time it runs out of space. Lists : Linear data structures, contain elements, each of which point to the "next" in the sequence as demonstrated in the examples below ( Simple, Circular and Double Linked Lists are some common kinds of lists ). However, this doesn't show a list being useful in anyway. It sequentially checks one by one of the array for the target element until a match is found or until all the elements have been searched of that array. Non-linear structure: trees. The data items are traversed serially one after another and all the data items in a linear data structure can be traversed during a single run. Data Structures (DS) tutorial provides basic and advanced concepts of Data Structure.

Overview of Data Structures | Set 1 (Linear Data Structures) 1. Note: Please use this button to report only Software related issues. The Probabilistic data structures and algorithms (PDSA) are a family of advanced approaches that are optimized to use fixed or sublinear memory and constant execution time; they are often based on hashing and have many other useful features. Structure for an element of the linked list A linked list contains a list of data The Data can be anything: number, character, array, structure etc structure, etc. This tutorial will give you a great understanding of Data Structures needed to understand the complexity of enterprise-level applications and need of. In non-linear data items are not in sequence. Let A be a. Data Structure is a way to store and organize data so that it can be used efficiently. Linked lists, stacks, queues, etc are linear data types. 4 Symbol Tables considers a quintessential data structure known as the symbol table for storing information, and two efficient implementations—hash tables and binary search trees. If the developer chooses bad data structure, the system does not perform well. Lists : Linear data structures, contain elements, each of which point to the "next" in the sequence as demonstrated in the examples below ( Simple, Circular and Double Linked Lists are some common kinds of lists ). Download Objective type questions of Data Structure PDF Visit our PDF store «. In non-linear data items are not in sequence. There are many technical posts about data structures you could have read instead. Tree vs Graph in Data Structure Since trees and graph are the non-linear data structures that are used to solve complex computer problems, knowing the difference between tree and graph in data structure is useful. Example is array. Rather, it's a description of a set of branches of math that all have in common the feature that they are "discrete" rather than "continuous". Though many candidates may never encounter data structures in day-to-day programming, showing a mastery of these concepts can help you rock your next interview—and add to your coding toolkit. Thus, longitudinal data combines the characteristics of both cross-sectional data and time-series data. Linear data structures. Here we have used C programming language to demonstrate some examples. Size of an array must be provided before storing data. For a rock-solid foundation, you may want to start with Search (linear and binary) and Sort (SortMerge and QuickSort). A data structure is said to be linear if the elements form a sequence, for example Array, Linked list, queue etc. This set of MCQ of data structure and algorithm includes solved multiple choice questions about linear and non-linear types of data structure, array and linear arrays. The prior knowledge of number of elements in the linear array is necessary. Namely: We can read this equation this way: If the input x is increased by a constant interval (Dx), then the output f(x) will also increase by a constant interval (bDx). Depending on the way the data is accessed data structures are divided into linear and non linear datatypes. Why Learn Linear Data Structures? Data structures are the way computer programs are able to store and retrieve data. There are two types of Data Structure: Primitive Data Structures Non-Primitive Data StructuresData Structure is very important to Prepare algorithm of any problem, and that algorithm can implement in any Programming Language. The equation y = x, for instance, is equivalent to a function that takes as its input a value for x and produces as its output a value for y. In this course, you will learn about and build the fundamental data structures of computer sciences. Though many candidates may never encounter data structures in day-to-day programming, showing a mastery of these concepts can help you rock your next interview—and add to your coding toolkit. In brief, it is easy to implement linear data structures in the. - Review the basic linear data structures - Demonstrate how each can be defined as an Abstract Data Type (ADT) - Demonstrate how each of these ADTs can be specified as a Java interface. Data structure means organizing the data by using models in the computer memory. 8 (27,077 ratings) Course Ratings are calculated from individual students’ ratings and a variety of other signals, like age of rating and reliability, to ensure that they reflect course quality fairly and accurately. In this course, Dhiman Mayank has discussed non-linear data structure. The data structure of choice here is a linear list, implemented in LEDA by the class list. Traversing- It is used to access each data item exactly once so that it can be processed. The size of lists, stacks, queues and trees must be determined in advance of using these data structures to ensure that the proper amount of memory is allocated for their elements. The relationship between linear and nonlinear data structures - is defined in terms of factor called principle of alignment. Linear data structures form sequences. A trigger is an SQL (structured Query Language) procedure that initiates an action when an event occurs. Linear Search and Binary Search Algorithms with Examples On December 20, 2016 January 4, 2017 By Kaushik Vaghani In Data Structure , Searching Algorithms Introduction to Searching. Search : Traverse the structure to find a particular element. Summary - Linear vs Nonlinear Data Structures. A classic example of a linear data structure is a linked list, where one link (called a node) in the list is directly related to the node next to it, or even on the opposite side, on a one-is-to-one basis. Sc Colleges. Following are the multiple choice questions (MCQs) or objective questions from Data Structures and Algorithms. If we add linear inductive types to the mix, we can also handle mutable data structures. It sequentially checks one by one of the array for the target element until a match is found or until all the elements have been searched of that array. Deductive systems were originally designed for educational purposes, helping students to translate the relational data structure model in a deductive data model, where "atomic data are arranged in predicates which can be understood as relations, i. net, 4shared. In this tutorial you know the difference between Linear and Non-Linear Data Structure in C. If the underlying data structure of Cntnr is based on a collision-chaining hash table, then modifying r_Cntnr will not invalidate its iterators' order; if the underlying data structure is a probing hash table, then this is not the case. Non-Linear container classes represent trees and graphs. Linear Search Algorithm with Example in Hindi, English for students of IP University Delhi and Other Universities, Engineering, MCA, BCA, B. Linked lists, stacks, queues, etc are linear data types. Thus, longitudinal data combines the characteristics of both cross-sectional data and time-series data. In a Linked List each node in the list stores data and reference to the next node. Here are different types of data structures:-. In non-linear data items are not in sequence. Elements in a nonlinear data structure do not form a sequence, for example Tree, Hash tree, Binary tree, etc. Non Linear are – Tree, Graph. – We move from item to item from the first item to the last item in the list. C++ has some built-in methods of storing compound data in useful ways, like arrays and structs. Though supervised variants exist, the typical manifold learning problem is unsupervised: it learns the high-dimensional structure of the data from the data itself, without the use of predetermined. Trees | Non-Linear Data Structure Part One: Binary Tree & BST October 12, 2018 October 12, 2018 While going through the various data structures in a previous post, I briefly touched on what an tree data structure is, on which I wanted to dedicate a separate post for. In his work, data structures for range max/min queries in d-dimensional OLAP datacubes were given, where an OLAP datacube (see [7, 11]) is modeled as a multidi-mensional array. data[11] D. In some cases, namely the linear ordering, there will be numerous abstract data structures each which will specialize by emphasizing specific operations. Notes on Data Structures and Programming Techniques (CPSC 223, Spring 2018) James Aspnes 2019-05-17T18:41:16-0400 Contents 1 Courseadministration13. Here the various operations on a data structure are possible only in a sequence i. Which of the following data structure is not linear data structure?. You will master lists, stacks, and queues, and learn about how computer memory. An array is a random access data structure, where each element can be accessed directly and in constant time. It will be shown that a sorting algorithm based on the heap (unsurprisingly called HeapSort) can achieve O(n log(n)) complexity and is easier to implement than MergeSort. Array, Stack, Queue, Linked List. From this chapter the study of data structure starts with the definition of data structure and classifying them as linear and non-linear data structures. Introduction to Data Structures and Algorithms Data Structure is a way of collecting and organising data in such a way that we can perform operations on these data in an effective way. Data Structures and Algorithms - Arrays - Array is a container which can hold a fix number of items and these items should be of the same type. Quadratic Probing is similar to Linear probing. Data Structures and Algorithms in Python provides an introduction to data structures and algorithms, including their design, analysis, and implementation. Keep the sequence in List. : Arrays, Records etc. Data Structures (DS) tutorial provides basic and advanced concepts of Data Structure. Searching. For example, one common data structure is the list or array , which is an ordered sequence of values. Even with a moderate load factor, primary clustering tends to slow retrieval. Stack works in a LIFO (Last in, First Out) manner. All elements assign the memory as random form and you can fetch data elements through random access process. The right selection of an appropriate data structure for solving a particular problem can prove very beneficial and also help reduce the complexity. Data frames combine the behaviour of lists and matrices to make a structure ideally suited for the needs of statistical data. C++ has some built-in methods of storing compound data in useful ways, like arrays and structs. 04 - extended linear address record 05 - start linear address record (MDK-ARM only) dd is a data field that represents one byte of data. The fact-checkers, whose work is more and more important for those who prefer facts over lies, police the line between fact and falsehood on a day-to-day basis, and do a great job. Today, my small contribution is to pass along a very good overview that reflects on one of Trump’s favorite overarching falsehoods. Namely: Trump describes an America in which everything was going down the tubes under Obama, which is why we needed Trump to make America great again. And he claims that this project has come to fruition, with America setting records for prosperity under his leadership and guidance. “Obama bad; Trump good” is pretty much his analysis in all areas and measurement of U.S. activity, especially economically. Even if this were true, it would reflect poorly on Trump’s character, but it has the added problem of being false, a big lie made up of many small ones. Personally, I don’t assume that all economic measurements directly reflect the leadership of whoever occupies the Oval Office, nor am I smart enough to figure out what causes what in the economy. But the idea that presidents get the credit or the blame for the economy during their tenure is a political fact of life. Trump, in his adorable, immodest mendacity, not only claims credit for everything good that happens in the economy, but tells people, literally and specifically, that they have to vote for him even if they hate him, because without his guidance, their 401(k) accounts “will go down the tubes.” That would be offensive even if it were true, but it is utterly false. The stock market has been on a 10-year run of steady gains that began in 2009, the year Barack Obama was inaugurated. But why would anyone care about that? It’s only an unarguable, stubborn fact. Still, speaking of facts, there are so many measurements and indicators of how the economy is doing, that those not committed to an honest investigation can find evidence for whatever they want to believe. Trump and his most committed followers want to believe that everything was terrible under Barack Obama and great under Trump. That’s baloney. Anyone who believes that believes something false. And a series of charts and graphs published Monday in the Washington Post and explained by Economics Correspondent Heather Long provides the data that tells the tale. The details are complicated. Click through to the link above and you’ll learn much. But the overview is pretty simply this: The U.S. economy had a major meltdown in the last year of the George W. Bush presidency. Again, I’m not smart enough to know how much of this was Bush’s “fault.” But he had been in office for six years when the trouble started. So, if it’s ever reasonable to hold a president accountable for the performance of the economy, the timeline is bad for Bush. GDP growth went negative. Job growth fell sharply and then went negative. Median household income shrank. The Dow Jones Industrial Average dropped by more than 5,000 points! U.S. manufacturing output plunged, as did average home values, as did average hourly wages, as did measures of consumer confidence and most other indicators of economic health. (Backup for that is contained in the Post piece I linked to above.) Barack Obama inherited that mess of falling numbers, which continued during his first year in office, 2009, as he put in place policies designed to turn it around. By 2010, Obama’s second year, pretty much all of the negative numbers had turned positive. By the time Obama was up for reelection in 2012, all of them were headed in the right direction, which is certainly among the reasons voters gave him a second term by a solid (not landslide) margin. Basically, all of those good numbers continued throughout the second Obama term. The U.S. GDP, probably the single best measure of how the economy is doing, grew by 2.9 percent in 2015, which was Obama’s seventh year in office and was the best GDP growth number since before the crash of the late Bush years. GDP growth slowed to 1.6 percent in 2016, which may have been among the indicators that supported Trump’s campaign-year argument that everything was going to hell and only he could fix it. During the first year of Trump, GDP growth grew to 2.4 percent, which is decent but not great and anyway, a reasonable person would acknowledge that — to the degree that economic performance is to the credit or blame of the president — the performance in the first year of a new president is a mixture of the old and new policies. In Trump’s second year, 2018, the GDP grew 2.9 percent, equaling Obama’s best year, and so far in 2019, the growth rate has fallen to 2.1 percent, a mediocre number and a decline for which Trump presumably accepts no responsibility and blames either Nancy Pelosi, Ilhan Omar or, if he can swing it, Barack Obama. I suppose it’s natural for a president to want to take credit for everything good that happens on his (or someday her) watch, but not the blame for anything bad. Trump is more blatant about this than most. If we judge by his bad but remarkably steady approval ratings (today, according to the average maintained by 538.com, it’s 41.9 approval/ 53.7 disapproval) the pretty-good economy is not winning him new supporters, nor is his constant exaggeration of his accomplishments costing him many old ones). I already offered it above, but the full Washington Post workup of these numbers, and commentary/explanation by economics correspondent Heather Long, are here. On a related matter, if you care about what used to be called fiscal conservatism, which is the belief that federal debt and deficit matter, here’s a New York Times analysis, based on Congressional Budget Office data, suggesting that the annual budget deficit (that’s the amount the government borrows every year reflecting that amount by which federal spending exceeds revenues) which fell steadily during the Obama years, from a peak of $1.4 trillion at the beginning of the Obama administration, to $585 billion in 2016 (Obama’s last year in office), will be back up to $960 billion this fiscal year, and back over $1 trillion in 2020. (Here’s the New York Times piece detailing those numbers.) Trump is currently floating various tax cuts for the rich and the poor that will presumably worsen those projections, if passed. As the Times piece reported:
