No. 5: Louisiana
Weaknesses: Health care, crime
Retirees in the Pelican State can put all the money they save from an affordable cost of living toward golden years filled with gumbo, po'boys and jambalaya.
Unfortunately, one of the major problems with Louisiana, which also made last year's list, is crime. The state recorded the 5th highest violent crime rate in the country in 2015, according to the FBI. It also had a murder rate double the national average in 2014.
The state also struggles with its health care system. The Agency for Healthcare Research and Quality gave Louisiana the 2nd lowest score in the nation for health care quality. The agency says Louisiana had a "worse than average" record for a variety of issues, including new AIDS cases and long-stay nursing home residents.
