Here is a neat interactive map of the US showing population and "racial" demographic changes over the last decade.
http://www.cnn.com/SPECIALS/defining.america/map/index.html I zoomed in so I could see Tulsa County, Oklahoma County and surrounding counties at the same time. Tulsa county grew by about 40,000 and Oklahoma County by about 58,000. And that gain wasn't from white folk for the white population in Tulsa county actually shrunk by about 15,000 and by a little over 17,000 in Oklahoma County during the same time period.
Its also interesting to zoom down to the census tract level and see where the population growth is in Tulsa. Its steady to losing in the mid-town/geographic center of Tulsa, and growing along the very edges and into the suburbs. But the other interesting thing is that Downtown within the IDL, was this island of red (growth) in a sea of white (decrease) saw a 13% increase in population which I am sure we will eeeasily trounce in this decade. If the last decades trends are similar to what this one will bring (and I think we could easily double or triple the number of new people living in downtown this decade compared to last) I predict that Downtown will have the highest, square mile, population density in the Tulsa region. So much for "Who on earth would want to live downtown? and "There is nothing downtown." naysayers.
And you know whats also fascinating? At the census tract level looking at the white population change, its growing in north Tulsa (directly north of downtown) and for the black population its decreasing in north Tulsa. I would not have bet on that being the case.
The square miles between Garnett and 129th from Pine all the way to 81st have seen significant Hispanic population increases in the last decade, often around 300% adding over 1,000 per sq mile.
