| Sumario: | <p>This study, known as the Los Angeles Neighborhood Services and Characteristics data (L.A.NSC) includes data from governmental and business data sources on the characteristics of census tracts in Los Angeles County from 1980 to 2010. The unit of analysis is 1990 census tract (census tracts using 1990 census tract boundaries). The data also include crosswalks for census boundaries across census years. It is public use data.</p> <p>The L.A.NSC data were assembled by the L.A.FANS projects to be used with L.A.FANS survey data restricted data versions 2, 2.5, and 3 all of which contain 1990 census tract numbers which can be linked with data in this file. However, the L.A.NSC files includes ALL census tracts in Los Angeles County, not just the 65 tracts sampled by L.A.FANS. Thus, the L.A.NSC data can be analyzed on their own without linkage to L.A.FANS survey data and provide longitudinal data on the characteristics of Los Angeles census tracts over a 30 year period.</p> <p>Additional information on the data is available at the <a href="https://lasurvey.rand.org/data/contextual/lansc/"> RAND website.</a> See also:</p> <p><ul> <li>The L.A.NSC Database Users' Guides (<a href="https://rand.org/pubs/working_papers/WR240z12.html">The Los Angeles Neighborhood Services and Characteristics Database: Codebook</a> and 2010 Neighborhood Services and Characteristics Database: NSC2).</li></ul></p>
