When countries attain material prosperity and women gain educational equality, full political rights, and access to good healthcare and contraception, birth rates plunge and most couples have just one or two children. They invest more time in these fewer, healthier children.30 In fact, even though mothers today have fewer children and spend far more time working outside the home than they did in 1965, they are spending more total time taking care of their children.31 Fathers’ time with kids has increased even more.
