This document presents a summary of a study that examines patterns of child care use in 2000-2001 for children ages 0-5 who were not yet enrolled in kindergarten or first grade. Specifically, the report examines whether or not non-parental child care was used, the primary type of child care used, the amount of child care used per week, the number of arrangements, the cost of care, and child-to-adult ratios in child care settings. It investigates the relationships between these child care measures and neighborhood, family, and child characteristics in Los Angeles County. It also considers the differences in child care patterns between the poorest families and others. The goal is to provide descriptive information on basic preschool child care use patterns in Los Angeles. The report is based on the results of the 2000-2001 Los Angeles Family and Neighborhood Survey (L.A.FANS), which is a representative survey of the county of Los Angeles.
