We set out to find [the best suburbs values] using a model from NeighborhoodScout.com, a statistical database that gathers figures from the U.S. Census, the National Center for Education Statistics, the Office of Federal Housing Enterprise Oversight, the FBI and the U.S. Justice Department at the granular neighborhood level. Every suburb within short range of the 15 largest metros was evaluated based on factors ranging from the quality of schools and the size and price of houses to the safety of the neighborhood and the education level of neighbors. Those that performed the best on all five metrics landed on our list of the three best-value suburbs for each city.
