Our key findings culminate in five recommendations for policymakers: First, tackle data security and privacy concerns by developing a clear and shared understanding of privacy laws, both within government and with the stakeholder community. Implement appropriate technology to ensure personally identifiable information will remain confidential. Second, create standard definitions for reporting administrative data and require implementation as a condition of local, state, and federal funding. Technological solutions can offer users a “continuum of access” that is aligned with their legal right to see and use the data. Most importantly, data must be used by researchers and policymakers to improve their quality. Third, take steps to instill a sharing and learning organizational mind-set. Implement a governance framework that is guided by shared values and transparency to facilitate appropriate sharing of administrative data. Fourth, create ease and comfort with using and sharing data by implementing data sharing in a tiered approach and open greater access over time. Fifth, at the federal level, standardize the collection of data and aggressively pursue data-sharing agreements with state and local governments. By linking administrative and survey data, US statistical agencies and independent researchers can more accurately report on Americans’ real conditions.
