Show 1489: The Baby Bust: Why Is Fertility Falling and What Can You Do About It?

Birth rates have been dropping for years. This is happening in many parts of the world, not just the US. Demographers estimate that women need to have 2.1 children, on average, to replace the population. (The US is currently at about 1.7 or 1.8 children per woman.)
