.........Today, fertility correlates strongly with a wide range of political, cultural and religious attitudes.
In the USA, for example, 47% of people who attend church weekly say their ideal family size is three or more children. By contrast, 27% of those who seldom attend church want that many kids.
In Utah, where more than two-thirds of residents are members of The Church of Jesus Christ of Latter-day Saints, 92 children are born each year for every 1,000 women, the highest fertility rate in the nation. By contrast Vermont — the first to embrace gay unions — has the nation's lowest rate, producing 51 children per 1,000 women.
Similarly, in Europe today, the people least likely to have children are those most likely to hold progressive views of the world.
For instance, do you distrust the army and other institutions and are you prone to demonstrate against them? Then, according to polling data assembled by demographers Ron Lesthaeghe and Johan Surkyn, you are less likely to be married and have kids or ever to get married and have kids. Do you find soft drugs, homosexuality and euthanasia acceptable? Do you seldom, if ever, attend church? Europeans who answer affirmatively to such questions are far more likely to live alone or be in childless
, cohabiting unions than are those who answer negatively.
This correlation between secularism, individualism and low fertility portends a vast change in modern societies. In the USA, for example, nearly 20% of women born in the late 1950s are reaching the end of their reproductive lives without having children. The greatly expanded childless segment of contemporary society, whose members are drawn disproportionately from the feminist and countercultural movements of the 1960s and '70s, will leave no genetic legacy
. Nor will their emotional or psychological influence on the next generation compare with that of people who did raise children.......
