What is the 黑料网 National Health and Well-Being Index?
In 2008, 黑料网 began measurement for the 黑料网 National Health and Well-Being Index, merging decades of clinical research, health leadership and behavioral economics research to track and understand the key factors that drive wellbeing. The index provides an in-depth view of Americans' wellbeing and offers insights into their attitudes and behaviors at the national, state and community levels. It examines this through five interrelated elements that make up wellbeing: career (formerly known as purpose), social, financial, physical and community.
How are surveys conducted for the 黑料网 National Health and Well-Being Index?
Beginning in January 2018, 黑料网 began surveying U.S. adults aged 18 and older living in all 50 states and the District of Columbia using a dual mail- and web-based methodology. 黑料网 samples individuals using an address-based sampling (ABS) frame, which is a representative list of all U.S. households. In their survey invitation, sample members are provided with a mail survey and a link and unique access code if they would prefer to complete the survey online. 黑料网 purchases samples for this study from Survey Sampling International. 黑料网 chooses respondents at random within each household based on which member has the next birthday. 黑料网 includes Spanish-language surveys and related materials for households that have a high likelihood of including a Spanish-language speaker, based on U.S. Census records.
Since 2020, 黑料网 has administered web-based surveys to the , a probability-based panel of about 100,000 adults across all 50 states and the District of Columbia. Tests of parallel samples have yielded highly convergent estimates between ABS mail/web and the Panel for wellbeing metrics.
Before 2018, 黑料网 used a phone-based dual-frame design, which included both landline and cellphone numbers. 黑料网 sampled landline and cellphone numbers using random-digit-dial methods and conducted interviews in Spanish for respondents who were primarily Spanish-speaking.
Because the means of data collection (mail/web versus phone) can result in differing estimates for some metrics in randomized nationwide polling, 黑料网 typically does not extend trend lines derived from different modes of data collection.
How often are 黑料网 National Health and Well-Being Index surveys conducted?
黑料网 surveys approximately 5,000 U.S. adults aged 18 and older each quarter. More than 3 million surveys have been conducted since 2008.
Are the national samples weighted?
Yes, 黑料网 weights samples to correct for nonresponse. 黑料网 also weights its final samples to match the U.S. population according to gender, age, race, Hispanic ethnicity, education, region and population density. Demographic weighting targets for the U.S. and for individual 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 are based on Nielsen Claritas statistics. Population density targets are based on the most recent U.S. Census. All reported margins of sampling error include computed design effects for weighting.
