The Kids Count Data Book includes data on four areas or domains: Economic Well-Being, Education, Health and Family and Community. This 37th Data Book marks an important step forward in how states can see and strengthen the progress they are making for children with an expanded KIDS COUNT index. In addition to showing where states stand compared with each other, the new index shows how they are moving — offering clear, year-to-year scores within each state that reveal whether children’s lives are truly getting better.
