Los Angeles Neighborhood Services and Characteristics Database

The Los Angeles Neighborhood Services and Characteristics (L.A.NSC) Database, a public use file, contains a variety of contextual variables for all Los Angeles County census tracts, based on tract definitions from the 1990 Census. The contextual measures describe tract demographic, social, economic, and physical characteristics. The data are primarily for 1990, although the range of years covered by the measures is from 1980 to 2003. The L.A.NSC Database is designed to support multilevel analyses of the L.A.FANS data, but has many other potential uses that are independent of the L.A.FANS household data.

Using the L.A.NSC Database with L.A.FANS

To use the L.A.NSC Database with the L.A.FANS household data, researchers must apply to use Version 2 or higher of the L.A.FANS Restricted Data. Versions 2 and higher of the Restricted Data identify Census tracts in the L.A.FANS household data, information that is necessary for linking the two databases.

L.A.NSC Database Documentation

The L.A.NSC Database Codebook provides a detailed description of the construction, organization, and content of the L.A.NSC Database. Users should read the L.A.NSC Database Codebook carefully before using the database and prior to contacting L.A.FANS with any questions.
