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. In January 2019, the PDI was temporarily suspended due to inconsistency in the number of panelists participating in the survey which led to the inability to report results on a state-level.
The Pharmacy Demand Report (PDR) was developed to provide an enhanced measurement of pharmacist demand in the United States. The inaugural PDR was released by the PWC in August 2020.
