The 20 best big-city neighborhoods for healthy living

Different neighborhoods in the same city can often vary greatly in the amenities and atmosphere they offer residents. And if staying active is important to you, it's best to do some research on the neighborhoods that will help you accomplish that.

Online real estate marketplace Trulia recently analyzed hundreds of neighborhoods in small, mid-sized, and large US cities to determine the best places to live a healthy, active life.

The results are based on the percentage of quiet streets (based off of traffic volume), the number of "active" amenities on Yelp (like playgrounds and parks), the number of health-centric amenities on Yelp (like hospitals and doctor's offices), and the amount of footpaths and trails (not including sidewalks).

Interestingly enough, a large majority of the top 20 neighborhoods were in Los Angeles and Seattle.
