The top communities on Money‘s Best Places to Live 2015 are not the wealthiest suburbs but they are fairly wealthy compared to national incomes. Only 7 have median household incomes less than $70,000 (the lowest is $57k) and 17 have median household incomes over $100,000. The median household income for the entire United States? $53,046 (data from 2009-2013).

Money’s methodology contributed to having communities with these income levels. Among other factors that went into creating these rankings:

-“[excluded] places with a median family income less than 80% of the state average”

-“Eliminate places with a median family income of more than 210% of the state average or a median home price over $1 million. Rank the rest on factors including job growth, diversity, and ease of living, giving the most weight to economic opportunity, housing affordability, education, and safety.”

In other words, the methods ensured that these communities couldn’t be too poor or too wealthy. Yet, the above-average incomes in these communities are connected to all sorts of other factors: not just jobs but higher-paying jobs (likely white collar), the money available in the tax base, the education level of residents, the kinds of available housing, and so on.

Could the average American live in these communities? Perhaps there would be some cheaper housing (that is a factor in these rankings though it is primarily about cost and not about having apartments and smaller and/or older houses) and the median household income suggests half of residents in these communities are below the figures posted here. However, these rankings are geared toward people of higher social classes.
