of residential units. A reverse Z score was used to prioritize NSAs with lower percentages of
residential addition investments.
Using the certificate of occupancy database, the total number of additions permits approved in
2012 was divided by the total number of residential parcels to obtain the percentage of single
family units that were added on to.

Percent Change in Income
– Percent change in median household income value was calculated
using the following equation:
2012 income – 2000 income
* 100
= % Change in MHI
2000 income
Some block group geographic boundaries shifted between 2000 and 2010. In these instances,
comparisons were made between the block groups whose geographic boundaries or areas most
closely aligned.
A reverse Z score was used to prioritize NSAs with higher negative changes in income.

Percent of Tax Delinquent Residential Parcels
- The percentage of residential property owners
who have failed to pay their property taxes.
This data is collected at the zip code-level. The percentage for each zip code was assigned to the
block groups whose centroids fell in the zip code boundary.
By utilizing the tax parcel database, each tax record was assigned to an NSA using GIS. Each tax
record was analyzed for residential use and this number was used as a proxy for the total number
of residential units.
The number of single family properties that have not paid their property taxes for 2012 as of
June 2013 was divided by the total number of single family properties to obtain the percentage of
single family properties that are tax delinquent.
