The 25 healthiest cities in America

Your personal decisions - diet, exercise, smoking, drinking - are crucial to living a healthy life, but some cities make living well easier and can have a huge effect on your overall health.

Niche, a company that researches and compiles information on cities, recently released its list of the healthiest cities in the US.

Niche assessed more than 220 cities with a population of more than 100,000, focusing on a group of factors that are important in measuring a healthy lifestyle, including obesity and smoking rates (taken from county level data) as well as availability and proximity to doctors and gyms. Niche also looked at other metrics, like the rate of excessive alcohol consumption and access to mental health providers.

Note that while some cities appear to have identical grades, each grade represents a range of scores, allowing some to rank higher despite both receiving an "A+", for instance. Read more about the methodology here.

California has the most cities on the list with 15 in the top 25 - including a handful from Orange County and neighboring Los Angeles County - but the healthiest city in the country is in Colorado.
