19. Omaha, Nebraska
The city of Omaha is the biggest in Nebraska, and it has become famous for being the home of Warren Buffet. In his documentary, he said that he was born and raised in Omaha, and he loves it enough to stay there the rest of his life. It also has a great cost of living. However, the crime rate has gone up by 10% in recent years, and an average of 1 in 23 people has become a victim of violent crime- meaning that pretty much everyone knows someone who has been mugged or robbed.
