1995 | CDC obesity data: now for all 50 states
For the first time, the government health agency is able to collect stats on body mass index numbers for the whole country. In 1995, one state has an obesity rate of more than 20% of the population. By 1999, that's true of 23 states. By 2004, all but six. By 2010, every state has at least that percentage, and in 16 states, more than 30% of the population is obese.
