Tune in to this recorded seminar featuring a new study matching anonymized cell phone data from SafeGraph on school visits to administrative school records. The research team from Drexel University and the University of Quebec at Montreal map changes in school visits during the pandemic to information on school learning modes to estimate EIPL for a sample of almost 70,000 schools that is highly representative of US public and private K-12 institutions. The analysis of the resulting data provides several new insights about disparities in EIPL over time and across regions.
