Over the years, I have heard baseball researchers ask if there was a "race database" somewhere.
For example. the National League was better than the American League throughout the 1960s and 1970s. From 1960 to 1982, the National League won 23 All-Star Games. The American League only won 2.
I would surmise that the National League dominated because they integrated more quickly, adding the best black players to their teams while a number of American League teams (most notably, the Red Sox) continued to stay all-white.
But I haven't seen data supporting that theory. That's because we have stats going back to the 1870s, but we don't have a database of racial/ethnic categorization. One reason is that every time it comes up, it becomes clear that "race" is a cultural phenomenon, not a scientific one. For example, President Obama is (at least) half-white and yet we call him the first "black" president.
So, forget "race". I'm working on a
skin color database, ranking everyone from 1-9 like so:
