I wonder how much 'Barbie" knows about Houston.
One night returning from the dock area of Houston, we took the wrong turnoff and got into the Hispanic barrios. They seemed to go on for miles. An area seldon seen by many Houstonians although they have stories about its dangers.

Looking up the population breakdown of the 2 million assigned to Houston, whites 49%, black 25%, Hispanic 37%. This adds up to 111% but this is because of the overlap of Latino and white in the way the figures are put together. I never have quite figured out how this works.
The metro population of Houston is close to 5 million; dunno how the percentages would translate for the whole area. I would guess that the percentage of whites is higher in metro, since this is where many white communities (inc. gated) have grown over the past 50 years.
