No. 8: Idaho
If cost of living, safety and weather are important to you, you'll want to consider Idaho as a good state for retirement.
It's one of the most affordable states in the U.S. Idaho also is one of the safest. The FBI recorded 1,984 property crimes and 208 violent crimes per 100,000 people in the Gem State in 2012. That's the lowest crime rate in the country.
And then there's the relatively pleasant weather. Yes, you'll still need a winter coat in Idaho. But there's a lot more to weather than just the temperature. For example, Boise, Idaho, gets more sunshine than Atlanta. And with an average annual humidity of about 58 percent, Idaho is naturally comfortable.
