Title: | Early Childhood Longitudinal Study, Birth Cohort (ECLS-B) Longitudinal 9-Month-2-Year Restricted-Use Data File and Electronic Codebook |
Description: | This CD-ROM contains an electronic codebook (ECB), a restricted-use data file, and survey and ECB documentation for the first and second waves of data collection for the Early Childhood Longitudinal Study, Birth Cohort (ECLS–B). NOTE: This file contains all cases that have participated in the ECLS-B, i.e., cases that participated in both the 9-month and 2-year collections, as well as cases that participated at 9 months but were nonrespondents at 2 years. This longitudinal file replaces the previously released 9-month cross-sectional restricted-use file. Users who are interested only in the 9-month data should use the 9-month data on this longitudinal file. |
