Penn’s World Well-Being Project launched a freely available interactive map showing county-level well-being, personality traits, and health indicators drawn from 37 billion geo-tagged tweets across the US. The five-year project involved ~20 Penn scientists and opens a new way to compare traits across all US counties — with applications in public health, policy, and community planning.
