Since 1990, the Casey Foundation has ranked states annually on overall child well-being using a selection of indicators. Called the KIDS COUNT index, these indicators capture what children and youth need most to thrive in four domains: (1) Economic Well-Being, (2) Education, (3) Health and (4) Family and Community. Each domain has four indicators, for a total of 16. These indicators represent the best available data to measure the status of child well-being at the state and national levels. This 35th KIDS COUNT Data Book is about ensuring kids have what they need to be ready to learn — because by the time these children reach the workforce, they must be ready to earn in a highly competitive global economy.
