Is Potomac a good place to live?

Yes, by almost any measure. Potomac earns an A, 40th among Maryland's 259 graded towns. It is among the healthiest towns in the country on CDC estimates, the median household earns $237K, and natural-hazard risk is low. The exception is cost of living: homes are expensive, about $1.3 million for a typical one and 10.6 times the Washington metro’s $127K median household income. 85% of adults 25 and older hold a bachelor’s degree or more in Potomac, above both Maryland’s towns (42%) and U.S. towns (29%). Potomac is easier to get around on foot or by transit than 90% of U.S. towns. Of the 154 Maryland towns we compare, none has a higher typical home value than Potomac.
