I am struggling to imagine which category is the flip category. If iowa is not doing better for white black or hispanic, which racial category is somlatge as to flip the average?
Texas:
50% Hispanic who average 25
50% white who average 29
State average: 27
Iowa:
10% Hispanic who average 24
90% white who average 28
State average: 27.6
https://en.m.wikipedia.org/wiki/Demographics_of_Texas It has 84% white population, not noticeably different to UK makeup at 87%
Iowa has 88% White (https://en.m.wikipedia.org/wiki/Iowa) or maybe 91 not too clear what they mean as difference between white and not hispanic
So them is some pretty small numbers to play with - somehow the "whites do better, and iowa has more whites" argument has only got 4-7% to play with
I would like to see the actual figures but it smells to me
Second, instead of looking at overall racial makeup of a state, you should be looking at the racial makeup of public schools. For Texas it’s been 52% Hispanic and 28% white. The former percentage is steadily rising year over year, while the latter is steadily falling.
Which makes the Simpson's paradox quite possible. So Texas does not have a racial makeup like UK. (I only have spent a little time in Houston, mostly I found it populated by cars)
