This report focuses on supply, demand and gaps in child-care seats (availability, quality and affordability). It also explores disparities based on child and family characteristics, including child/family demographics, and maternal/adult and child health. Interspersed with the data are quotes from the City of Boston Census regarding parents/guardians’ firsthand experiences with child care in the city. This report’s estimates set a baseline understanding to help focus and track investments and policy changes for early childhood. (author abstract)
