Though San Antonio is the eighth safest major city in the US, it falls near the bottom of the list of the safest cities in Texas. This doesn't necessarily mean that this city isn't a safe place to retire since some neighborhoods are safer than others, but it isn't a good first choice for retirees looking for a peaceful, crime-free life. The safest city in Texas to retire is Fulshear, with a violent crime rate of 0 per 1000 people.
