The notion that the middle class is shrinking is controversial because the economic boundaries that define the middle class vary. Households that earn between $25,000 and $75,000 represent approximately the middle half of the income distribution tables provided by the
U.S. Census Bureau. Over the past two decades, the number of households in those brackets decreased by 3.9%, from 48.2% to 44.3%. During the same time period, the number of households with incomes below $25,000 decreased 3.5%, from 28.7% to 25.2%, while the number of households with incomes above $75,000 increased over 7%, from 23.2% to 30.4%.
[45] A possible explanation for the increase in the higher earnings categories is that more households now have two wage earners.
[46] However, a closer analysis reveals all of the 7% increase can be found in households who earn over $100,000.

Poverty rates increased early in the 1980s until late in the 1990s when they started to go back down. Since 2000, the percent of all people living in poverty has risen from 11.3% to 15.1% in 2010.

A study by
Brookings Institution in June 2006 revealed that Middle-income neighborhoods as a proportion of all metropolitan neighborhoods declined from 58 percent in 1970 to 41 percent in 2000. As housing costs increase, the middle class is squeezed and forced to live in less desirable areas making upward mobility more difficult. Safety, school systems, and even jobs are all linked to neighborhood types
