The National Child Care Study 1990: Low-Income Substudy
Sandra L. Hofferth, April Brayfield, Sharon Deich, Pamela Holcomb, and Frederic Glantz

The study is a nationally representative survey of 972 households with total annual incomes below $15,000 and one or more children under age 13. The survey was conducted in February-July of 1990 and focused on what kinds of child care arrangements respondents used, how those arrangements were chosen, and how they were paid for. The survey included a schedule of when the respondent and his or her spouse or partner was at work, and a schedule of when each child was at each child care arrangement to provide a detailed picture of the correspondence between child care arrangements and work. Extensive data on employment history were gathered, including the relationship between work and child care in the past. Basic demographic information such as income, education, and ethnic group is also included. There are 1,419 variables in all. The questionnaire was administered over the telephone with the interviewer using a CATI (Computer Aided Telephone Interview) system. The Low-Income Substudy was designed to supplement the number of low-income households included in a larger "main" child care study (archived separately as AFDA Data Set Nos. 13-14). A total of 430 parent interviews were completed with eligible low-income households as part of the low-income substudy, resulting in an interviewer completion rate among eligible households of 78%. Combining these 430 interviews with the 672 low-income interviews from the main study yields a total of 1,102 low-income parent interviews. Of these, only 974 actually had family incomes under $15,000 and are included in this substudy.
