I’m hosting a panel discussion tomorrow on our new projections of the effects of the federal immigration program on future population growth. Short version: current immigration policies will artificially increase our population by more than 100 million people by 2060. After my research director presents his results, Ben Wattenberg will say they’re a good thing, then Roy Beck of Numbers USA will disagree. Much wonkish wrangling will ensue. (It turns out that “wonkish wrangling” is a googlenope – though not for long!)
