Download Data for the Child Population

From this page you can download the data for the under-18 population that were used to prepare these web pages. You can download the full dataset, or you can choose a subset of that file.

There are two things to keep in mind when using this data:

  • There are two types of missing values in this file. A value of -998 indicates that the data has not yet been released from the Census Bureau. A value of -999 indicates that the variable is not applicable to the specific metropolitan area. For example, if there are no Hispanics in an area, segregation indices for Hispanics would not be calculated.

  • The files contain a single row of column headers followed by rows of data for each metropolitan area. The column headers are not very descriptive, so click here for a list of variable descriptions.

Option 1 - Download the full file
The full file contains information for all metropolitan areas for both 1990 and 2000, including racial and ethnic population totals, dissimilarity indices, and exposure indices. It contains values for the total metropolitan area, as well as its central city and suburban portions separately.
