Another excellent piece from a demographer, this time Stuart Gietel-Basten, on how "pronatalism is a dead end" "Without addressing the root causes of low fertility—inequality, instability, and the incompatibility of work and family life—top-down efforts to “encourage” childbearing will fail"

Nigel Farage supports the scraping the two-child benefit cap as a way of encouraging people to have more children. But pronatalist policies that offer a one-off "baby bonus" are not effective.
