From the abstract:
After nearly a decade of decline, the number of children living in low-income families has increased significantly since 2000. This data book provides national and 50-state trend data on the characteristics of low-income children over the past decade: parental education, parental employment, marital status, family structure, race and ethnicity, age distribution, parental nativity, home ownership, residential mobility, type of residential area, and region of residence.
The most current year of data can also be accessed at www.nccp.org–see NCCP’s 50-State Demographic Profiles or build custom tables using NCCP’s 50-State Demographics Wizard. For a discussion of these data and selected policy implications, see NCCP’s fact sheets on low-income children, which are updated annually.
