Like the richest towns in the vast majority of states, Newtown’s poverty rate was among the lowest in the country.

10. Tyrone, Georgia
> Town median household income: $85,188
> State median household income: $49,179
> Town population: 6,933
While Tyrone’s poverty rate of 8.3% was lower than the national rate of 15.4% and less than half the state’s rate of 18.2%, it was considerably worse than the poverty rates of the richest towns in the vast majority of states. Nearly 17% of the area’s workforce was employed in the transportation, warehousing, and utilities industry, several times higher than the statewide proportion of 5.9%, which itself was the fourth highest compared to other states. These jobs often tend to be lower-wage occupations.
