In 2007, at the climax of Housing Bubble and the Bush-Kennedy-McCain amnesty push, the Hispanic fertility rate peaked at 102.2 births per 1,000 Hispanic women 15-44, versus 95.9 in the pre-Bush economic peak year of 2000. By 2009, however, the Hispanic fertility rate had fallen off to 93.3. The Hispanic total fertility rate fell from 3.00 in 2007 to 2.73 in 2009. However, illegitimacy continues to increase, growing from 51.3 percent of Hispanic mothers being unmarried in 2007 to 53.2 percent in 2009.
In contrast, the fertility rate among non-Hispanic white youngish women was much lower and somewhat more stable, increasing from 57.7 in 2000 to 60.1 in 2006, then falling to 58.5 in 2009. The white total fertility rate fell from 1.87 to 1.78. The illegitimacy rate among whites grew from 27.8 percent in 2007 to 29.0 percent in 2009.
The picture we see is that the Bush Administration's policy of encouraging dubious mortgages to narrow the racial gap in homeownership rates and goose the economy sucked in illegal immigration and boosted Hispanic fertility. How exactly that would help the GOP in the long run is one of those questions that just isn't even conceivable to the GOP's team of crack strategists.
There's an intellectual No Fly Zone over most anything having to do with population beyond the most banal.
