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.
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.
