Changing Geographic Patterns Of High- And Low-Income Groups In Eight United States Metropolitan Areas, Taylor J. Hafley

Electronic Theses and Dissertations

Income segregation produces unequal social outcomes and has steadily increased since the 1970s. High-poverty neighborhoods suffer from low performing schools, fewer jobs, an evaporation of local role models (Wilson 1987; Reardon and Bischoff 2011a). Recent evidence suggests growing income inequality influences the segregation of affluence more than the segregation of poverty (Reardon and Bischoff 2011b). Metropolitan areas that display strong population and economic growth are susceptible to higher levels of income inequality. I use three unique quantitative approaches to measure the segregation of affluence and poverty in a comparison of four metropolitan areas exhibiting strong growth to four metros with …
