Some Stunning Demographic Trends in Employment

I spent most of the weekend studying the latest employment report from the Bureau of Labor Statistics (BLS). They have a wealth of employment data, much of which stretches back to 1948. My focus was the Labor Force Participation Rate (LFPR) with some specific attention to gender and age.

The LFPR is a simple computation: You take the Civilian Labor Force and divide it by the Civilian Noninstitutional Population. The result is the participation rate expressed as a percent.

The first chart below splits up the data since 1948 in two ways: by age and by gender. For the former, I chose the 25-64 age cohorts to represent what we traditionally think of as the "productive" (pre-retirement age) work force. The BLS has data for ages 16 and over, but across this 64-year time frame college attendance has surged dramatically. So I opted for age 25 as the lower boundary to reduce the college-years skew.

Note the squiggly lines for the productive years and jumbled dots for the older cohorts. These result from my use of non-seasonally adjusted data. The BLS does have seasonally adjusted data for some cohorts, but not the older ones, so I used the non-adjusted numbers for consistency.

The next chart eliminates the squiggles with a 12-month moving average. I've also added some callouts to quantify the data in 1948 and the present.

It doesn't take Ph.D. in sociology to recognize some significant changes in the chart above. The growth of women in the workplace, the solid red line, was a major trend. The financial advantage of two income households was boosted by Title VII of the Civil Rights Act of 1964, which prohibits discrimination by race, color, religion, sex, or national origin. The Age Discrimination in Employment Act of 1967 helped to stabilize the decline in the 65 and over participation rate, at least until the 11-month recession that started in December 1969.

As for the age 25-64 cohorts, the participation rate for men peaked way back in May 1954 at 95.9%; for women it was 46 years later in May 2000 at 72.7%, and for the combined cohort is was in March 1998 at 80.2%.

The dotted lines representing ages 65 and over also illustrate some dramatic changes. Visions of the good life in retirement, assisted by a burgeoning Social Security system, was a standard expectation for the pre-Boomer generations. The advent of Medicare in 1965 and Social Security COLAs (cost-of-living adjustments) in 1975 added to their confidence in the Golden Years.

However, the LFPR for the "elderly" (a term I use respectfully as a member of that cohort) flattened out in the mid-1980s and then began increasing -- slowly at first and more significantly around the turn of the century, even as the numbers for the productive cohort continued to decline. The next chart gives us a clearer look at the relative patterns of growth and contraction.

Since January 2000, the participation rate for all the elderly has soared by 50 percent and by slightly more than 60 percent for elderly women.

Labor Force Participation Rate by Age Groups Since 2000

The next chart shows the non-seasonally adjusted data for six age cohorts since 2000 with no gender distinction. Two recessions and two savage market selloffs were no doubt major drivers of the trends we see here.

While the LFPR growth for the elderly is the most striking feature in the chart above, we also see a noticeable decline for the youngest cohort. A significant driver of this trend has been the decision to stay in (or go back to) school for more education. Supporting evidence is found in the eye-popping growth of student loan debt, especially since the onset of the Great Recession. To be sure, some of that trend is accounted for by older cohorts heading back to school in hopes of improving their employment prospects.

Another interesting if less conspicuous line in thechart of the six age cohortsabove is the blue one, representing ages 45-54. Household income data tells us that this age bracket has the distinction of being the peak earning years. For more on this topic, seethis commentary. The LFPR for the peak earners is down 3.6% from the turn of the century.

Our Aging Work Force

I'll close this commentary with a pair of pie charts showing the change in the six cohorts from 2000 to 2012.

For some simple math: In 2000, the three younger cohorts constituted 66% of the workforce. Now they have shrunk to 56%, which means the 45 and older workers have grown from 34% to 44% of the labor force. In the late 1990s the dream of early retirement was common among the Boomers. But the reality is that they are increasingly delaying retirement, and many who did retire have now reentered the workforce.

There is little doubt that the two 20th century recessions and major market selloffs devastated the retirement readiness for a great many of the individuals nearing that milestone. And many who had retired were ultimately forced to reenter the workforce to make ends meet.

Footnote on Data Revisions : The BLS's monthly employment data is probably the most closely watched economic report, especially in light of the Fed's linkage of monetary policy with the unemployment rate. Friday's news of 236K new jobsin February made headlines in the financial press. History tells us, however, to have little confidence in its accuracy, for the series is subject to substantial revisions. How substantial? For some particulars, see the this BLS publicationshowing the rather amazing revisions since 1979.

In contrast, the Labor Force Participation Rate discussed in this commentary is based on large enough numbers that historical revisions are quite small. For example, if we study the revisions of the 16-and-over LFPR since 1948, the earliest changes date from 1994. Since then, the initial LFPR number has been revised about 62 percent of the time. Most revisions were 0.1 percent, a few were 0.2 percent, and only once has there been a revision of 0.3 percent; that was for February 2000, the month before the market peaked. That data point was dropped by 0.2 percent in the January 2001 report and another 0.1 percent 25 months later in the February 2003 report.

My data source for the charts and numbers in the commentary is the BLS's Databases & Tools page -- specifically the Labor Force Statistics here.
