This data set contains over 400 unique variables for 241 neighborhoods. The variables are those 100-percent and sample data questions used by the U.S. Census Bureau in the creation of its demographic profiles.

Variables in the data
In this data file, most of the variables also include a corresponding percentage. For instance, there is a variable for males and a corresponding variable showing the percentage of males in the neighborhood. Including the percentage columns, there are actually 775 variables in the file.

In general:
Demographic profile 1 is the profile of general demographic characteristics
Demographic Profile 2 is the profile of selected social characteristics
Demographic Profile 3 is the profile of selected economic characteristics
Demographic Profile 4 is the profile of selected housing characteristics

The following variables are in addition to the demographic profiles: about 18 variables related to “School Enrollment by Type of School (Private or Public)” and about 12 variables related to “Tenure by Occupants Per Room in owner occupied housing units and renter occupied housing units.” In the codebook listing, these variables are labeled AD1-AD37.

To obtain the list of variables, see the technical documentation for the demographic profiles or our short codebook (Excel Format), which includes all the variables.

Neighborhoods
This file contains data for 241 neighborhoods. In order to maintain confidentially, neighborhoods with a total population below 300 could not be reported. Those neighborhoods were grouped into two categories SN=Small Neighborhoods or PNR= PREDOMINATELY NON-RESIDENTIAL. The following table indicates the neighborhoods falling into these categories.

Statistical Rounding
To maintain confidentiality, the Census Bureau applies statistical procedures that introduce some uncertainty into data for small geographic areas with small population groups.

All cells in any Census 2000 special tabulation must be rounded. The rounding schematic is:

0 remains 0
1 7 rounds to 4
8 or greater rounds to nearest multiple of 5 (i.e., 864 rounds to 865, 982 rounds to 980)
Any number that already ends in 5 or 0 stays as is.

Here are other Disclosure Review Board rules that apply to the special tabulation data.
