Why Do People Keep Having Children? A New Freakonomics Radio Podcast

What are the factors that make a given person more or less likely to have children? How important are income, education, and optimism about the future? Is it true that "development is the best contraceptive," as demographers like to say? And is the global population really going to double by the next century? (Probably not -- in fact, one U.N. estimate finds that the population in 2100 could be lower than today.)

These are some of the questions we ask in this week’s episode, “Why Do People Keep Having Children?” (You can subscribe to the podcast at iTunes, get the RSS feed, or listen via the media player above.
