This report 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. This report contains five chapters. Following an introduction, Chapter Two provides a brief overview of the L.A.FANS study and outlines the child care measures collected by L.A.FANS. The results of the analysis are presented in Chapter Three, examining the association between child care patterns and key geographic, socioeconomic, and demographic characteristics. The specific variables included in the analysis were chosen primarily because they represent major socioeconomic and demographic groups of interest to policymakers in Los Angeles County. At the neighborhood level, differences by service planning areas (SPAs)--which represent geographic regions of Los Angeles County--and neighborhood poverty levels are examined. At the family level, the report examines the relationship of child care with maternal education, work status, income, race/ethnicity, maternal nativity status, marital status, and whether the mother was a teenager when she had the child. It also examines differences in child care by children's age and sex. Chapter Four focuses on child care use by poorer families in the sample and investigates how they pay for child care. Low-income families are of particular interest to policymakers because they are least able to afford high-quality child care. Finally, Chapter Five summarizes the main conclusions of the report. Appended are "Questions on Child Care in L.A.FANS" and a bibliography. (Contains 13 figures and 8 tables.) [This report was prepared for the First 5 LA.]
