The Gallup-Healthways Well-Being Index is the first-ever daily assessment of U.S. residents’ health and well-being. By interviewing at least 1,000 U.S. adults every day, the Well-Being Index provides real-time measurement and insights needed to improve health, increase productivity, and lower healthcare costs. These datasets represent aggregate survey data that are non-identifiable to the respondents and provide useful measures of consumer views over time. Developers, designers and experts can build applications that integrate these measures with other elements of consumer health to gain better insight into health policy implications, new products and services, and many other applications.
