The 2021 report captures the conditions of the city’s childcare market at an unstable point in time. The data presented in this report captures supply and demand for childcare in the first quarter of 2021 as the impacts of the first wave of the COVID-19 pandemic were beginning to wane, reopening was gaining steam, and the impact of the second-wave Delta variant was not yet fully understood. In addition to the typical level of data validation performed each year, Reinvestment Fund conducted a phone survey and cross-referenced OCDEL license data with state-provided lists of permanently and temporarily closed programs. Data were further compared with state Child Care Works subsidy records to identify active sites that were still enrolling subsidized children. The purpose of these additional validation steps was to identify and remove sites that had an active license but were not actively providing childcare. (author abstract)
