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. There are two L.A. NSC datasets available. The first covers the period from 1980 to 2003, although most of the data come from 1990. The second file updates the data (using 1990 census tract boundaries) to include the 2010 census data. 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.
L.A. FANS data are distributed by the Data Sharing for Demographic Research (DSDR) Project at the University of Michigan. For information about using these data, visit https://www.icpsr.umich.edu/icpsrweb/DSDR/series/846.
