Brownback released a statement containing this, in part: “In the past year, we have seen more than 20,000 new jobs in Kansas and a total of 45,600 new jobs created from January 2011 through October 2013.” (Click here for the full statement.)
Davis released a statement containing this, in part: “From January 2011 – Oct 2013: Period during which Brownback cites 46,500 new jobs … Employed: +3,634 (not 46,500, which is what was claimed by Brownback)” (Click here for the full statement.)
So which campaign is correct? The answer is not easy to provide. That’s because there are two series of employment data provided by the Bureau of Labor Statistics. The two series don’t measure exactly the same thing, and each campaign has chosen to use the series that benefits their campaign. Nearby is an example of just how different the two series can appear.
A document from BLS titled Employment from the BLS household and payroll surveys: summary of recent trends explains in brief: “The Bureau of Labor Statistics (BLS) has two monthly surveys that measure employment levels and trends: the Current Population Survey (CPS), also known as the household survey, and the Current Employment Statistics (CES) survey, also known as the payroll or establishment survey. … These estimates differ because the surveys have distinct definitions of employment and distinct survey and estimation methods.”
Another BLS document explains in detail the differences between the CPS and CES data. For example: CES: “Designed to measure employment, hours, and earnings with significant industrial and geographic detail” CPS: “Designed to measure employment and unemployment with significant demographic detail.”
Another difference: CES: “Self-employed persons are excluded.” CPS: “Self-employed persons are included.” (See Understanding the employment measures from the CPS and CES survey.)
I’ve prepared a table showing the claims made primarily by the Davis campaign (since it provided the most detail) and gathered data from both the CES and CPS series. I’ve also showed the seasonally adjusted data compared to the raw data when available. Sometimes the numbers match exactly with the claims made by the campaigns, and sometimes the numbers are a little different. Click here for the full table.
I’ve also created an interactive visualization of the CPS and CES data for Kansas. Click here to open it in a new window.
Each campaign uses the data that best makes its case. Generally speaking, the CES data shows larger employment gains.
