The 2010 census numbers are in, and the "official" population of the United States is 308,745,538. That sounds like a lot. The population according to the 1950 census was 150,697,361. No wonder the stores seem so crowded! On the other hand, I just heard that with only three days left until Christmas, one in five people had not started their Christmas shopping yet. My question, obviously, is this: Who did a poll to find this out? Out-of-work former census workers??
