Another question is: are black software engineers under-represented at Twitter? Not blacks, but black software engineers. There may be more or fewer black software engineers per capita among blacks compared to other races. For example, if more or fewer blacks graduate college per capita among blacks, then we would likely expect to find more or fewer black software engineers per capita.
