long description of table

In 1975, the typical Texas prison inmate was a young, urban minority male below average in intelligence. For the most part that is the picture of today's inmate too. Minorities continue to make up a large majority of the prison population, far more than their share of the total population, as we saw previously. Overwhelmingly, too, Texas prisons house men, but today aging men. In 1975 more than three-quarters were under 35 years of age. Today the majority is over 35. Inmate IQ scores in 1975 were below average (average is approximately 100) and appear to have declined somewhat since then. Finally, the majority of inmates today still come from the state's major metropolitan areas, though the percentages from smaller Texas cities and more rural Texas counties have grown significantly since 1975. The most striking change in Texas prison inmates, though, is locked in the mushrooming prison population itself. In 1975, about 150 of every 100,000 Texans was in a state prison facility. By 2002, more than 579 of every 100,000 Texans was imprisoned by the state. And that's not counting tens of thousands of prisoners (as of 2002) housed in private prisons and state, county, and municipal jails.
