Tag Archives: Visualizations

Following are visualizations of data. Many are interactive and created using Tableau Public. In some cases I’ve recorded myself using the visualization to tell a story, and all you have to do is watch.

Kansas Special Congressional Election

An interactive map of voting in the special congressional election in Kansas district 4, for Sedgwick County only.

Intensity of red indicates higher percentage of votes for Ron Estes. By using the interactive map (link below) you may zoom and pan. Click on a precinct to see details of its vote. Precinct sizes — in terms of the number of voters — vary widely. Precincts cast anywhere from one to 950 votes.

This is data for Sedgwick County only. (It’s the only data I have at the moment.) Sedgwick County cast 67.9 percent of the votes in the district.

Wichita metro employment by industry

An interactive visualization of Wichita-area employment and jobs by industry.

The Bureau of Labor Statistics, part of the United States Department of Labor, makes monthly employment statistics available. I’ve gathered them for the Wichita metropolitan area and present them in an interactive visualization.

This data comes from the Current Employment Statistics, which is a monthly survey of employers asking about jobs.1

The four tabs along the top of the visualization hold different views of the data; one table and three charts. Employment figures are in thousands. All series except one are not seasonally adjusted.

Tax collections by the states

An interactive visualization of tax collections by state governments.

Each year the United States Census Bureau collects data from the states regarding tax collections in various categories. I present this data in an interactive visualization.

The values are for tax collections by the state only, not local governmental entities like cities, counties, townships, improvement districts, cemetery districts, library districts, drainage districts, watershed districts, and school districts.

Of particular interest is the “State Total” tab. Here you can select a number of states and compare their tax burdens. (Probably three or four states at a time is the practical limit.) This data is presented on a per-person basis.

The example shown below compares Kansas and Colorado. Many might be surprised to know that tax collections in Kansas are higher than in Colorado, on a per-person basis.

Data is as collected from the United States Census Bureau, Annual Survey of State Government Tax Collections, and not adjusted for inflation. Visualization created using Tableau Public. Click here to access the visualization.

Personal income in the states

An interactive visualization of income growth and change in the states, by major sector.

The Bureau of Economic Analysis, an agency of the United States Department of Commerce, collects and analyses data regarding the U.S. and world economies. One series is personal income, defined by BEA as “Personal income is the income received by, or on behalf of, all persons from all sources: from participation as laborers in production, from owning a home or business, from the ownership of financial assets, and from government and business in the form of transfers. It includes income from domestic sources as well as the rest of world. It does not include realized or unrealized capital gains or losses.”1

Data is available for farm and non-farm income. I’ve gathered this data from BEA and present it in an
interactive visualization. This is a series named SA4. Data is subdivided farm or non-farm, and also by state and regions. There are three views of data. Some work best with just two or three states, while others can show many states. You may choose a range of dates (this data is annual through 2016). Also, select one or more states or regions. Click on the legend to highlight one or more series. Trends over time are shown as percentage change from the first year so that comparisons may be made.

Of note is the steep decline in farm income in Kansas and other Plains states.

Economic indicators for the states

An index of past economic activity for each state, and another index looking forward. Presented in an interactive visualization.

The Federal Reserve Bank of Philadelphia calculates two indexes that track and forecast economic activity in the states and the country as a whole.

The coincident index is a measure of current and past economic activity for each state.1 This index includes four indicators: nonfarm payroll employment, the unemployment rate, average hours worked in manufacturing, and wages and salaries (adjusted for inflation). July 1992 is given the value 100.

The leading index anticipates the six-month growth rate of the state’s coincident index.2 In addition to the coincident index, “the models include other variables that lead the economy: state-level housing permits (1 to 4 units), state initial unemployment insurance claims, delivery times from the Institute for Supply Management (ISM) manufacturing survey, and the interest rate spread between the 10-year Treasury bond and the 3-month Treasury bill.”

Positive values mean the coincident index is expected to rise in the future six months, while negative values mean it is expected to fall.

I’ve created an interactive visualization of these two indexes. An example appears nearby. Click here to open the visualization in a new window. You may select a range of dates and one or more states to include on the chart. Click on a state’s legend color to spotlight it against other states.

Kansas tax receipts

Kansas tax receipts by category, presented in an interactive visualization.

The Kansas Division of the Budget publishes monthly statistics regarding tax collections. I’ve gathered these figures present them in an interactive visualization. In the visualization, there are these available tabs:

Table: A table of data. For each month the two data items supplied by the state are the actual value and the estimated value. This table also holds the computed variance, or difference, between the actual value and the estimated value. A positive number means the actual value was greater than the estimated value.

Collections: Shows monthly collections for each component. Because monthly numbers vary widely, this data is presented as the moving average of the previous 12 months.

Annual Change: Shows the change from the same month of the previous year. A positive value means the value for the month is greater than the same month last year.

Estimates: The Governor’s Consensus Revenue Estimating Working Group provides monthly estimates. This chart shows the variance, or difference, between the actual value and the estimated value. A positive number means the actual value was greater than the estimated value.

Running Total Estimates: This is the cumulative sum of the estimate variances, reset to zero at the start of each fiscal year (July 1).

Running Total Change from Prior Year: This is the cumulative sum of the monthly changes from the prior year, reset to zero at the start of each fiscal year (July 1).

Since July 2014, individual income tax collections have been relatively flat. Corporate income tax collections are on a slight downward trajectory.

Retail sales tax and compensating use tax have been mostly rising. A higher sales tax rate took effect on July 1, 2015, with the rate rising from 6.15 percent to 6.50 percent.

Cigarette taxes rose rapidly since July 2015 when higher tax rates on these products took effect. After peaking, collections are declining.

Severance taxes — tax collected on natural gas and oil as it is extracted from the ground — have been on a downward trend since July 2014 as prices for these products have fallen. This is a sizable tax. In June 2014 collections of this tax were running at about $143 million per year. For February 2017, the rate is $32 million annually.

Kansas employment by industry

An interactive visualization of Kansas employment by industry.

The Bureau of Labor Statistics is an agency of the United States Department of Labor. It describes its mission as: “The Bureau of Labor Statistics of the U.S. Department of Labor is the principal Federal agency responsible for measuring labor market activity, working conditions, and price changes in the economy. Its mission is to collect, analyze, and disseminate essential economic information to support public and private decision-making. As an independent statistical agency, BLS serves its diverse user communities by providing products and services that are objective, timely, accurate, and relevant.”1

BLS provides monthly employment statistics. It has just updated revised numbers for 2016. I’ve gathered these for Kansas and present them in an interactive visualization.

This data comes from the Current Employment Statistics, which is a monthly survey of employers.2

The tabs along the top of the visualization hold different views of the data. Employment figures are in thousands. You may view seasonally adjusted or unadjusted data. Some views display the number of jobs, while others display the change in jobs by industry since the first year or month that is selected. When using the charts that display annual averages, be aware that using a time selection with a partial year will not provide accurate results.

Two “industries” that are closely followed are “Total Nonfarm” and “Total Private.” These, obviously, are not industries in themselves, but are sums of other industries. There are other examples like this.

State and local government employee and payroll

Considering all state and local government employees in proportion to population, Kansas has many, compared to other states, and especially so in education.

When considering all state and local government employees, Kansas spent $254 per person on payroll (March only).1 This was 15th highest among the states, District of Columbia, and the nation as a whole. There were 14.9 citizens for each FTE (full-time equivalent employee), which ranks fourth highest.

Example from the visualization. Click for larger.
In other words, Kansas has many government employees compared to other states, and these employees are costly, again compared to other states. This is data from the U.S. Census Bureau for 2015, the most recent year for which data is available.

When considering all elementary and secondary education employees, Kansas spent $95 per person on payroll (again, March only). This was 12th highest among the states, District of Columbia, and the nation as a whole. There were 34.3 citizens for each FTE (full-time equivalent employee) working in elementary and secondary education, which ranks third highest.

In other words, Kansas has many elementary and secondary education employees compared to other states, and these employees are costly, again compared to other states.

Similar results are found for higher education employees. Fortunately, Kansas has zero employees working in state-owned liquor stores.

Spending in the states, by fund

The National Association of State Budget Officers publishes spending data for the states. In this interactive visualization, I present the data in a graphical and flexible format.

Data for each state is subdivided by fund (see below for definitions). Data through 2015 is actual, while data for fiscal year 2016 is estimated. The figures for the “state” United States were computed by summing the spending in all states, then dividing by the U.S. population. These figures are not adjusted for inflation.

In the example from the visualization that is shown below, we see general fund spending for Kansas and selected states. Note that general fund spending on a per-capita basis in Kansas is higher than in Oklahoma, Colorado, and Missouri, and approximately the same as Texas. When using the visualization you may select states, funds, and time periods to create your own comparisons. Because the visualization is interactive, you can do things like clicking on legends to highlight data series.

Of note is the tab comparing spending in states that have an income tax vs. those that have no income tax. Click here to access the visualization.

Example from the visualization, showing general fund spending for Kansas and selected states. Click for larger version.

From NASBO, definitions of the funds.

General Fund: The predominant fund for financing a state’s operations. Revenues are received from broad-based state taxes. However, there are differences in how specific functions are financed from state to state.

Federal Funds: Funds received directly from the federal government.

Other State Funds: Expenditures from revenue sources that are restricted by law for particular governmental functions or activities. For example, a gasoline tax dedicated to a highway trust fund would appear in the “Other State Funds” column. For higher education, other state funds can include tuition and fees. For Medicaid, other state funds include provider taxes, fees, donations, assessments, and local funds.

Bonds: Expenditures from the sale of bonds, generally for capital projects.

State Funds: General funds plus other state fund spending, excluding state spending from bonds.

Kansas state school assessments

An interactive presentation of Kansas state school assessment scores at the state, district, and building levels.

Kansas State Department of Education makes available school assessment results at its website Kansas Building Report Card, available at ksreportcard.ksde.org. The present assessments were first given in 2014, although results for that year were not made available.1

KSDE background explains that scores on the tests are categorized in four levels: “Kansas assessment results are now reported in four levels. Level 1 indicates that student is not performing at grade-level standards. Level 2 indicates that the student is doing grade-level work as defined by the standards but not at the depth or level of rigor to be considered on-track for college success. Level 3 indicates that the student is performing at academic expectations for that grade and is on track to being college ready. Level 4 indicates that the student is performing above expectations and is on-track to being college ready.”

When KSDE presents assessment results through the report card website, it shows the percent of students whose scores fall into each category. While this is useful, I present the data in a different way, using these categories:

  • Level 1
  • Level 2 or higher
  • Level 3 or higher
  • Level 4

Thus, “Level 2 or higher” holds the percentage of students doing grade-level work or better, and “Level 3 or higher” holds the percentage of students on track to being college ready or better.

There are three visualizations, one for building-level results, another for district-level results, and another for state-level. (Because of the differing sizes of buildings and districts, it is not possible to simply aggregate statistics to a higher level.)

GDP by state and industry

An interactive visualization of GDP for each state, by industry.

The Bureau of Economic Analysis is an agency of the United States Department of Commerce. BEA describes its role as “Along with the Census Bureau, BEA is part of the Department’s Economics and Statistics Administration. BEA produces economic accounts statistics that enable government and business decision-makers, researchers, and the American public to follow and understand the performance of the Nation’s economy. To do this, BEA collects source data, conducts research and analysis, develops and implements estimation methodologies, and disseminates statistics to the public.”

One series BEA produces is gross domestic product (GDP) by state for 21 industry sectors on a quarterly basis. BEA defines GDP as “the value of the goods and services produced by the nation’s economy less the value of the goods and services used up in production.” It is the value of the final goods and services produced.

In describing this data, BEA says “These new data provide timely information on how specific industries contribute to accelerations, decelerations, and turning points in economic growth at the state level, including key information about the impact of differences in industry composition across states.” This data series starts in 2005. An announcement of the most recent release of this data is at Gross Domestic Product by State: Third Quarter 2016.

I’ve gathered the data for this series for all states and regions and present it in an interactive visualization using Tableau Public. The data is presented in real dollars, meaning that BEA adjusted the numbers to account for changes in the price level, or inflation.

In the visualization you may use several different presentations of the data and filter for specific states, industries, and time intervals. Besides a table of values, the series are presented as percentage change over time since the first values, so that growth, rather than magnitude, of GDP is shown.

Kansas school employment

Kansas school employment rose slightly for the current school year, and ratios of employees to pupils fell, also slightly.

Kansas school employment. Click for larger.

Kansas school employment. Click for larger.
Figures released by the Kansas State Department of Education show the number of certified employees rose slightly for the 2016-2017 school year.

The number of Pre-K through grade 12 teachers rose to 30,431 from 30,413, an increase of 0.06 percent. Certified employees rose to 41,459 from 41,405, or by 0.13 percent.1 These are not the only employees of school districts.2

Enrollment fell from 463,504 to 460,491, or 0.61 percent. As a result, the ratios of teachers to students and certified employees to students fell. The pupil-teacher ratio fell from 15.2 pupils per teacher to 15.1. The certified employee-pupil ratio fell from 11.2 to 11.1.

The relative change in enrollment and employment is not the same in every district. To help Kansas learn about employment trends in individual school districts, I’ve gathered the numbers from the Kansas State Department of Education and present them in an interactive visualization. Click here to use it.

These figures, at least on a state-wide basis, are contrary to the usual narrative, which is that school employment has been slashed, and class sizes are rising rapidly. The pupil-teacher ratios published by KSDE are not the same statistic as class sizes. But if the data shows that the ratio of pupils to teachers is largely unchanged for the past five years and class sizes are rising at the same time, we’re left to wonder what school districts are doing with teachers.

Kansas school spending, an interactive visualization

An interactive visualization of spending for Kansas school districts.

The accompanying visualization holds both nominal dollar amounts and amounts adjusted to reflect 2016 dollars. Data includes state aid, local aid, federal aid, and total spending for each school district, both total and per pupil. The visualization includes both tables and charts.

Kansas school spending, entire state, through 2016. Click for larger. This is an example from the visualization.
Kansas school spending, entire state, through 2016. Click for larger. This is an example from the visualization.
For the school year ending in 2016, total spending per pupil was $13,015. This is down from an inflation-adjusted $13,222 for 2015, a decline of 1.56 percent. Considering state funding only, per-pupil funding for 2016 was $8,540, down from an inflation-adjusted $8,631 for 2016, a decline of 1.05 percent.

In fiscal year 2015 there was a shift in the way property tax revenue is reported, with revenue formerly counted as “local” being counted as “state.” One of the tabs in the visualization shows the sum of local and state values, which eliminates the effect of the change in reporting.

Kansas Policy Institute has spending data without KPERS (retirement) spending at Non-KPERS funding sets another per-pupil record in 2015-16.

Spending and revenue data is from Kansas State Department of Education. Inflation-adjusted data calculated using Consumer Price Index, all items, 1982-84=100 (series CUUR0000SA0) from U.S. Bureau of Labor Statistics. The price level used for 2016 is for the first half of 2016. Visualization created using Tableau Public.

Pupil-teacher ratios in the states

Kansas ranks near the top of the states in having a low pupil-teacher ratio.

Pupil-teacher ratios in the states for 2015. Click for larger.
Data from National Center for Education Statistics, ELSI Elementary and Secondary Information System, shows that Kansas is near the top of the states in pupil-teacher ratio, meaning that Kansas has many teachers compared to the number of students. NCES is a division of the U.S. Department of Education.

A common complaint in Kansas is that class sizes have been rising. While pupil-teacher ratio is not the same measure as class size, the question is this: If Kansas has a low pupil-teacher ratio, but class sizes are (purportedly) large and rising, what are these teachers doing?

In the chart of pupil-teacher ratios over time, we see that while the ratio in Kansas rose for the 2015 school year, the trend over time is down, meaning that the number of teachers has increased faster than enrollment. The ratio for 2015 is the same as for 2008, and lower than the years before then.

Also, note the position of Kansas compared to other states. The pupil-teacher ratio in Kansas is lower than in most states.

This data is available in an interactive visualization. You may select different views of the data, and filter for specific states and time frames. Click here to access the visualization.

Employment by MSA and industry

An interactive visualization of employment in metropolitan areas.

Employment data from the Bureau of Economic Analysis, an agency of the United States Department of Commerce, is available for all metropolitan areas and major industries. I present this data in an interactive visualization using Tableau Public. In this visualization you may access several different presentations of the data. You may filter for specific areas, industries, and time periods. The data is available in a table of employment numbers, or in series presented as the percentage change since the first value. This illustrates relative growth, rather than magnitude, of employment. This is annual data from BEA table CA25N1 through 2015, the last year available at this time.

In the nearby example from the visualization we can see that Wichita has performed poorly compared to some peers of interest.

You may use the visualization yourself by clicking here.

Personal income in the states

An interactive visualization of personal income growth and change in the states.

An updated version of a smiliar visualization is here.

The Bureau of Economic Analysis, an agency of the United States Department of Commerce, collects and analyses data regarding the U.S. and world economies. One series is personal income, defined by BEA as “Personal income is the income received by, or on behalf of, all persons from all sources: from participation as laborers in production, from owning a home or business, from the ownership of financial assets, and from government and business in the form of transfers. It includes income from domestic sources as well as the rest of world. It does not include realized or unrealized capital gains or losses.”

This interactive visualization presents personal income data from BEA. Data is subdivided by state, along with regions and the entire country. There are four views of data. Some work best with just two or three states, while others can show many states. You may choose a range of dates (this data is quarterly). Also, select one or more states or regions.
