Mind The Gap

We have been engaged in decades-long public policy debates on gaps and how best to close them: the income gap, the student achievement gap, gender-linked gaps in employment opportunities. But why do we care so much about gaps? In a land of diversity, why are subgroup differences such a concern?

At a basic level, we care about gaps because (or when) our fundamental assumption is that, on a “level playing field," there should be no systematic differences among people based on ascribed traits, such as race and gender, that are unrelated to the “game." It is “ok” if a specific Hispanic kid performs at a lower level than his/her white counterpart or vice-versa. But it’s not ok if, on average, Hispanic students’ test scores systematically lag behind that of similar white children. Why? Because we know intelligence and ability are normally distributed across racial/ethnic groups. So, when groups differ in important outcomes, we know that this "distance” is indicative of other problems.

What problems exactly? That is a more complex question.

An Uncertain Time For One In Five Female Workers

It’s well-known that patterns of occupational sex segregation in the labor market – the degree to which men and women are concentrated in certain occupations – have changed quite a bit over the past few decades, along with the rise of female labor force participation.

Nevertheless, this phenomenon is still a persistent feature of the U.S. labor market (and those in other nations as well). There are many reasons for this, institutional, cultural and historical. But it’s interesting to take a quick look at a few specific groups, as there are implications in our current policy environment.

The simple graph below presents the proportion of all working men and women that fall into three different occupational groups. The data are from the Bureau of Labor Statistics, and they apply to 2011.
