What is the Gallup-Sharecare Well-Being Index?
The Well-Being Index measures Americans’ perceptions of their lives and their daily experiences through five interrelated elements that make up well-being: sense of purpose, social relationships, financial security, relationship to community, and physical health.
Gallup and Sharecare in 2012 created the Gallup-Sharecare Global Well-Being Index to measure well-being worldwide. Gallup added 10 questions to its World Poll in 2013, with each of the questions associated with one of the five elements of well-being. Gallup compiles individual responses and categorizes the respondents as thriving, struggling, or suffering in each element. The Global Well-Being Index uses the same data collection and weighting methodology as the Gallup World Poll.
How are interviews conducted for the Gallup-Sharecare Well-Being Index?
Gallup interviews U.S. adults aged 18 and older living in all 50 states and the District of Columbia using a dual-frame design, which includes both landline and cellphone numbers. Gallup samples landline and cellphone numbers using random-digit-dial methods. Gallup purchases samples for this study from Survey Sampling International (SSI). Gallup chooses landline respondents at random within each household based on which member had the most recent birthday. Each sample of national adults includes a minimum quota of 50% cellphone respondents and 50% landline respondents, with additional minimum quotas by time zone within region. Gallup conducts interviews in Spanish for respondents who are primarily Spanish-speaking.
How many people are interviewed as part of the Gallup-Sharecare Well-Being Index?
Gallup interviews at least 500 U.S. adults aged 18 and older daily. More than 175,000 respondents are interviewed each year, and over 2 million interviews have been conducted to date since 2008.
How often are Gallup-Sharecare Well-Being Index interviews conducted?
Since it began in 2008, the Gallup-Sharecare Well-Being Index survey has been conducted every day, excluding major holidays and other events, for 350 days per year.
Are Gallup-Sharecare Well-Being Index samples weighted?
Yes, Gallup weights samples to correct for unequal selection probability, nonresponse, and double coverage of landline and cellphone users in the two sampling frames. Gallup also weights its final samples to match the U.S. population according to gender, age, race, Hispanic ethnicity, education, region, population density, and phone status (cellphone only, landline only, both, and cellphone mostly). Demographic weighting targets for the U.S. and states are based on the most recent Current Population Survey figures for the aged 18 and older U.S. population, while weighting targets for metropolitan areas and congressional districts are based on Nielsen Claritas statistics. Phone status targets are based on the most recent National Health Interview Survey. Population density targets are based on the most recent U.S. Census.
