Have more babies.
As wife_of_charlespeirce will tell you, I love statistics. One area that particularly fascinates me is demographics, and more specifically, why the US is still having babies while the rest of the developed world is not. German women have 1.4 babies each, which means that in Germany they're closing elementary schools and nurseries, the tax burden on the working class is growing, and the population is projected to shrink by 9 million (to 73.6 million) by 2050. (hans, does this concern you? Where's your German hegemony now!)
Meanwhile, we're chugging along here in the US. While Hispanics have a nominally higher birthrate once they get here, nearly all races in America have an average of 2 babies each, keeping us at replacement. Add immigration to that, and our population is still growing. (We're projected to hit 300 million in October.) In Italy the Pope is telling the people to have more children, and Putin in Russia is offering to pay families to do so.
This is from the Washington Post article linked to above:
What explains the American exception? Eberstadt cites three differences with Europe and most other advanced countries: greater optimism, greater patriotism and stronger religious values. There's some supporting evidence. A survey by the National Opinion Research Center at the University of Chicago asked respondents in 33 countries to react to this statement: "I would rather be a citizen of [my country] than of any other." Among Americans, 75 percent "strongly" agreed; among Germans, French and Spanish, comparable responses were 21 percent, 34 percent and 21 percent, respectively.
(Mair, you should get a kick out of that: citing optimism, patriotism and religious values as demographic/sociological explanations moves toward that human factor you appreciate and want to see more of in sociology.)
Here's the CIA's listing of all fertility rates. Does this represent the Death of the West, or is it just a phase?
