Background
The Pharmacy Workforce Center, a nonprofit corporation comprised of nine national pharmacy professional organizations, financed the Pharmacy Aggregate Demand Index (ADI) and the Pharmacist Demand Indicator (PDI). The ADI (which began in 1999) and the PDI (which was transitioned from the ADI in 2016) collected and disseminated data on the demand for pharmacists in the United States utilizing a panel of pharmacist employers.
