Expanding on previous child care supply analysis, the Center for American Progress collected data on infant and toddler child care supply from 19 states and the District of Columbia. In total, the sample represents close to 40 percent of the U.S. population. This study finds that in these states: - There are more than four children under age 3 per licensed child care slot, or enough licensed child care to serve just 23 percent of infants and toddlers. - Licensed child care is more than three times as scarce for children ages 0 to 2 than it is for those ages 3 to 5.7 - Using CAP's working definition for child care deserts—places where there are three or more children for each licensed child care slot—more than 80 percent of the counties in this study would be classified as an infant and toddler child care desert.
