Many states face a “data deficit” without essential data on the size of the workforce and basic demographic and workforce metrics. Data deficits may exist because states and localities: Lack access to basic data, such as data on credentials, qualifications, and compensation levels, or more detailed data on shortages, stability, and quality. Do have access to data, but use legacy systems that are difficult to adapt, use data systems that operate in siloes or are not integrated across data sources, or lack the analytic capacity to address key policy questions. Lack effective processes, intra- and inter-agency relationships, or public or private research partnerships to analyze data and share findings. Some states have made progress towards addressing the data deficit and associated challenges by building capacity through public or private partnerships, updating data systems, and integrating data across sectors. This series of data snapshots describe how five states—Florida, Iowa, Nebraska, Oregon, and Virginia—have leveraged partnerships and policy contexts to successfully use workforce data for impact.
