For this interactive map and set of state profiles, we analyzed data on parents’ online reviews of child care providers to understand how the historic decline in HBCC providers is associated with parents’ overall experiences with the child care market (including both HBCC and center-based providers). We found that, as the number of HBCC providers declined, parents in 37 states left more negative child care reviews than positive reviews. Negative reviews included those on important topics that relate to child care quality, such as cost, convenience, warmth of staff, and academics. This resource illustrates the decline of HBCC providers by state from 2010 to 2019, as well as trends in online reviews of all child care providers. (author abstract)
