These six computer files contain social and demographic data about children and their families in the following states: (1) California; (2) Florida; (3) Illinois; (4) New York; (5) Pennsylvania; and (6) Texas. Data for 1980/81 and 1985/86 are reported. Data will eventually be provided for the 11 largest states. One file is for all children; the second file is for black children. The following column variables are included: (1) family structure; (2) parent educational attainment; (3) mother's age; (4) ethnicity; and (5) parent employment pattern. The following row variables are included: (1) child characteristics; (2) economic characteristics; and (3) selected maternal and paternal characteristics. The following features are included: (1) instructions are on-screen; (2) files can be manipulated to create several user-specified two-way tables; (3) population numbers can be percentaged; (4) longitudinal data can be indexed by year; and (5) individual tables can be printed. The files, which are on diskettes, are used on a personal computer with Lotus 1-2-3, Version 2.0 or higher. The data may also be retrieved by other programs that can import Lotus files, but the user may not be able to take advantage of all of the features. At least 512K of memory is needed, but 640K is recommended if the user loads other applications. FREQUENCY: . TYPE OF SURVEY: Population. POPULATION: Children; Black Youth. SAMPLE: . RESPONDENTS: .
