Though definitions vary, economists and researchers generally characterize the middle class as households that earn approximately two-thirds to two times the median national income. Slightly more than half (52%) of American households are middle-class, according to the Pew Research Center, a decline from 61% in 1971. But the middle-class squeeze — featuring lowered living standards, a decline in real wages and the rising expense of consumer goods and housing — has has hobbled the cohort’s upward mobility. Still, some places in the U.S. are better suited than others to this socio-economic class.
