Actual Number of Households by Race/Ethnicity and Income
versus
Expected (Free Market) Number of Households by Race/Ethnicity and Income
What became clear through the analysis is that different racial and ethnic groups are not
spread throughout Lake County as much as would be predicted if income was the sole
determinant of household location.
In reviewing the free market analysis, several factors must be kept in mind:
The Free Market Analysis in and of itself does not definitively confirm that
housing discrimination exists or does not exist in a given census tract. The Free
Market Analysis must be viewed in combination with the other portions of this
Analysis of Impediments as well as the policies and actions of the local
government.
Census tracts 8630.03, 8630.05, and 8630.06 are excluded from the analysis as
all of the housing is reserved for personnel assigned to Great Lakes Naval
Station.
Information on income by race/ethnic group was obtained from the 2012
American Community Survey 5-Year Estimates. Therefore the information
presented provides the average characteristics of households over the five-year
period.
While the ACS is the most reliable source of data on households, it is based
upon a sample of households not the entire population of households.
Consequently the data provided by the ACS is subject to sampling and nonsampling errors.
On the following pages are Exhibits III-26 through III-29 that map the difference
between the comparison cited above; that is, the difference between the actual
percentage of members of a racial or ethnic group that actually live in the census tract
and the expected percentage of members of a racial or ethnic group based solely on
income. Negative numbers indicate that fewer members of that racial or ethnic group
live in the census tract than would have been predicted. Positive numbers indicate that
more members exist in the census tract than would have been predicted based solely
on income.
In addition to conducting the Free Market Analysis by census tract, AREA also
conducted the analysis by place. The analysis by place varies from the analysis by
census tract because the census tract looks at the characteristics of all of Lake County
whereas the place analysis considers only municipalities. Each analysis provides a
slightly different view of each location but both indicate that factors outside of income
result in households concentrating by race and ethnicity in different portions of Lake
County. Exhibits III-30 through III-33 provide maps of the municipality analysis.
