Although birth rates have declined in America over the last four decades – and since 2008 in particular – a new study finds that immigrants are contributing disproportionately to keeping the US birth rate afloat. In fact, the 2014 rate for foreign-born women is similar to the rate for U.S.-born women in 1970. Bill Frey says that’s a good thing: “My view is that we actually need more young people in this country and that immigrants and their children are going to fill that need.”
