The demographics of the labor force participation rate

There is much lamenting about the decline in the labor force participation rate. As we recently discussed on this blog, while the rate decreased quickly during the previous recession and its recovery, the overall decline began several years before. This decline indicates there must be more than cyclical or even policy-related forces at work. One likely candidate is demographics. In the graph above, the proportion of the U.S. population 25 to 54 years of age follows a pattern similar to that of the labor force participation rate over the past 10 years. Why look at this 25-54 age range? Because this group has the highest labor force participation rate. So, if the share of this age group is declining, the aggregate labor force participation rate is likely to decline as well.

How this graph was created: For the first line, search for “population 25-54” and select “Civilian noninstitutional population—25-54 years.” To create the ratio, add the “Civilian noninstitutional population” series via the “Add Data Series” option: When you add this series, be sure to select “Modify existing series” for series 1. Then use the “Create your own data transformation” option using the formula a/b*100 so that the result is expressed in percentages. For the second line, simply add the civilian labor force participation rate as series 2.

Don’t be deceived by seasonality

In the graph above, the two series have the same label, yet they tell very different stories: The red line bounces between a few values, and the blue line shows a large increase last summer and then a decrease this winter. The difference is that the blue line reflects raw data, while the red line has been adjusted for seasonal regularities. Obviously, we need to take into account that the labor force participation rate increases every summer; only then can we correctly analyze how the economy is faring. Otherwise, one could draw false conclusions, especially by looking at a single year.

Expanding the sample period reveals the obvious seasonal variations in the path of the blue line, and the graph below shows this. (You can also use the slider bar under the graph above to achieve the same view.) Note, however, that these seasonal variations are not as strong as they used to be, presumably because the economy has become less sensitive to weather conditions.

How these graphs were created: Search for “Labor force participation,” select the two series you want, and click on “Add to Graph.” Limit the sample period to one year for the top graph and fully expand the sample period for the bottom graph.

Who’s paid the minimum wage?

The minimum wage is back in the news, and FRED can offer some insights. FRED includes data from the Bureau of Labor Statistics—specifically, in the Current Population Survey—that tally the number of workers who are paid the federal minimum wage. Note that some states, counties, and cities mandate minimum wages above the federal level and that some workers can be paid less (e.g., service workers who receive tips). The graph tracks the number of workers paid the federal minimum wage or less, which is affected by the minimum wage itself, how wages and labor productivity have changed since the last time the minimum wage was raised, how inflation has eroded the nominal minimum wage, and finally how other polities approach their own minimum wage with respect to the federal minimum.

What does the graph show? Currently, a little over a million workers are paid the federal minimum wage, and most of them are not employed full-time. Their numbers were much higher a few decades ago, but the federal and other minimum wages were not the same back then. A little less than a million workers are paid less than the federal minimum wage, a large majority of whom are employed full-time. FRED has these latter data series only as far back as 2000, so it is difficult to judge any trends in these numbers.

How this graph was created: Go to the US Bureau of Labor Statistics source, choose “Weekly and Hourly Earnings from the Current Population Survey,” then choose the “minimum wage” tag in the sidebar. Select the series you want and add them to the graph.
