How Low Income Neighborhoods Change: Entry, Exit, and Enhancement

The 1990s were a decade of economic improvement for low-income neighborhoods.  The number of high-poverty neighborhoods declined (Jargowsky, 2003), and the number of low-income neighborhoods experiencing a gain in average income greatly exceeded those experiencing a decline. In this study we have three research questions focused on neighborhoods that gain economically.  First, do we indeed find evidence of displacement, particularly among those with fewest resources?  Second, what are the sources of neighborhood income change? Are the sole sources of change selective entry and exit, or does incumbent upgrading also play a role?  And finally, what other changes accompany neighborhood income gains?
