This E.D. TAB provides descriptive information about children born in the United States in 2001. It is the first publication based on the Early Childhood Longitudinal Study, Birth Cohort (ECLS?B), and it presents information on certain child and family characteristics, on children's mental and physical skills, on children's first experiences in child care, and on the fathers of these children. The report profiles data from a nationally representative sample of children at about 9 months of age both overall, and for various subgroups (i.e., male and female, children from different racial/ethnic groups, and children living in different types of families). Appended are: (1) Technical Notes and Glossary (includes: Survey Methodology, Response Rates, Data Reliability, Statistical Procedures, and Glossary: Constructs and Variables Used in Analysis); and (2) Standard Error Tables.
