Spatial Mismatch of the Poor: An Explanation of Recent Declines in Job Isolation

:Despite years of spatial mismatch hypothesis research, the poor’s access to jobs is not well understood. This article provides a detailed analysis of the distributional imbalance between the residential locations of poor and nonpoor families and jobs over the 1990s in U.S. metropolitan areas. Descriptive and multivariate evidence are presented addressing whether job access for the poor has improved over the 1990s. If so, what factors drove the improvement, and do they help explain the disparity in job access between the poor and nonpoor? Using data from the U.S. Census, the Economic Census and the Zip Code Business Pattern files, the analysis reveals how the change in metropolitan factors over the 1990s explains the gap in job access between the poor and nonpoor. Specifically, the factors which increase parity or exacerbate it are identified. Results indicate that job access for the poor has improved significantly, particularly for black poor over the decade. A decomposition of job isolation indicates that change in dynamic metropolitan-wide factors such as job sprawl and the variation of housing affordability overall impedes movement toward parity in access to jobs between the poor and nonpoor.
