The Robert Wood Johnson Foundation's (RWJF) new Data Hub tracks state-level data and allows users to visualize, customize, and share facts and figures on key health care topics. Users select a category and an indicator to create a map or rankings report, and can modify reports as appropriate by payer, income, educational attainment, race/ethnicity, or timeframe. Data Hub is part of RWJF's commitment to providing timely, accessible information and evidence to inform health policies and practices. The online resource establishes a system of priority measures for monitoring state-level progress toward improving the nation's health and health care.
