Problem. The Chicago area is markedly different from just ten years ago. Downtown living has become commonplace with the conversion of office buildings, warehouses and factories into condominiums. New single-family homes have replaced abandoned railyards in the South Loop. Whole neighborhoods have turned around, while others have become targets for speculation by investors trying to predict the next hot area. And, public housing is being demolished and replaced with mixed-income communities.
Change is not without consequence. Spurred by an influx of private capital and public investment, these improvements have forced low-income households to relocate, often involuntarily to other communities and usually into poorer areas to keep housing costs down. In turn, many of these families end up sending children to a new school in the middle of the year and spending more time and money commuting to work and services.


Implications. The intent of this research is to enable researchers, community partners and others to discuss policy initiatives in the areas of transportation, criminal justice, health, economic development, housing, education and community development that can begin to address negative effects of uneven development and rapid neighborhood change.

Neighborhood Change Index

Factors. Using data that was in the census, the variables in the index include: Median family income, % Families below poverty, Median house value, % Owner-occupied housing, Race / Ethnicity (White, African American, Latino), % Children age 5-19 (school age children), % Elderly (age 65+)2, % Managers and professionals (of all workers), % Adults with college education, % Children enrolled in private schools, % Female-headed households with dependent children under age 18. Using the 1970, 1980, 1990 and 2000 Census data, we compared the data for the 13 factors in each community area to the same factors for the city as a whole. If a factor was positively associated with gentrification, and a community area had a higher value for this factor than the city as a whole, it received a score of +1. If a factor was negatively associated with gentrification and the community area had a lower percentage for this factor than the city as a whole, the area would also receive a score of +1 for that factor. The maximum value a community area could receive would be +13 and the minimum value a community area could receive would be –13.

Typology. Based on the maps and scores for the community areas, we constructed a neighborhood “typology.” The division separated community areas that had changed from those that had not changed, because by definition, gentrification and decline are processes of change. In our analysis we defined significant change as a change in + / – 4 points in the total “score” for a community area, over a period of 10 years.
