Visualizing black unemployment in the U.S.

In a prior post, I explained how the aggregate unemployment rate paints a misleading picture of the employment situation in the United States. Even though the U3 unemployment rate in 2019 has returned to the lowest level we have seen in decades, the aggregate statistic hides some concerning trends. There is an alarming rise in the proportion of people considered "not in labor force" by the Bureau of Labor Statistics - these forgotten people are not counted as "employable": when a worker drops out of the labor force, the unemployment rate ironically improves.

In that post, I looked at the difference between men and women. This post will examine the racial divide, whites and blacks.

I did not anticipate how many obstacles I'd encounter. It's hard to locate a specific data series, and it's harder to know whether the lack of search results indicates the non-existence of the data, or the incompetence of the search engine. Race-related data tend not to be offered in as much granularity. I was only able to find quarterly data for the racial analysis while I had monthly data for the gender analysis. Also, I only have data from 2000, instead of 1990.


As before, I looked at the official unemployment rate first, this time presented by race. Because whites form the majority of the labor force, the overall unemployment rate (not shown) is roughly the same as that for whites, just pulled up slightly toward the line for blacks.


The racial divide is clear as day. Throughout the past two decades, black Americans are much more likely to be unemployed, and worse during recessions.

The above chart determines the color encoding for all the other graphics. Notice that the best employment situations occurred on either end of this period, right before the dotcom bust in 2000, and in 2019 before the Covid-19 pandemic. As explained before, despite the headline unemployment rate being the same in those years, the employment situation was not the same.


Here is the scatter plot for white Americans:


Even though both ends of the trajectory are marked with the same shade of blue, indicating almost identical (low) rates of unemployment, we find that the trajectory has failed to return to its starting point after veering off course during the recession of the early 2010s. While the proportion of part-time workers (counted as employed) returned to 17.5% in 2019, as in 2000, about 15 percent more whites are now excluded from the unemployment rate calculation.

The experience of black Americans appears different:


During the first decade, the proportion of black Americans dropping out of the labor force accelerated while among those considered employed, the proportion holding part-time jobs kept increasing. As the U.S. recovered from the Great Recession, we've seen a boomerang pattern. By 2019, the situation was halfway back to 2000. The last available datum for the first quarter of 2020 is before Covid-19; it actually showed a halt of the boomerang.

If the pattern we saw in the prior post holds for the Covid-19 world, we would see a marked spike in the out-of-labor-force statistic, coupled with a drop in part-time employment. It appeared that employers were eliminating part-time workers first.


One reader asked about placing both patterns on the same chart. Here is an example of this:


This graphic turns out okay because the two strings of dots fit tightly into the grid while not overlapping. There is a lot going on here; I prefer a multi-step story than throwing everything on the wall.

There is one insight that this chart provides that is not easily observed in two separate plots. Over the two decades, the racial gap has narrowed in these two statistics. Both groups have traveled to the top right corner, which is the worst corner to reside -- where more people are classified as not employable, and more of the employed are part-time workers.

The biggest challenge with making this combined scatter plot is properly controlling the color. I want the color to represent the overall unemployment rate, which is a third data series. I don't want the line for blacks to be all red, and the line for whites to be all blue, just because black Americans face a tough labor market always. The color scheme here facilitates cross-referencing time between the two dot strings.
