These four Census Briefs highlight the information from the 2000 U.S. Census most relevant for community leaders, policy makers, advocates, and others concerned with the status of children and families in Rhode Island. The first brief graphs the large increase in the number of Rhode Island children. Two tables show child population in core cities (1990 and 2000) and child population by city and towns (1990 and 2000), and one figure shows state child populations (1980-2000). The second brief delineates the population of children in Rhode Island by age category, finding that there are more early adolescents and fewer young children. Two tables show children by age category (1990 and 2000) and child population by age group (2000), and one figure shows children by age category (1990 and 2000). The third brief delineates the state's growing diversity led by an increase in Hispanic children. Two tables show children under age 18 by race and ethnicity, and children under age 18 by race and ethnicity and city or town. The fourth brief charts the rise in the number of children living in single-parent families. One figure shows children's living arrangements (1970-2000), and one table shows children under age 18 living in family households (census 2000). (SD)
