For results based on this sample of national adults, the margin of sampling error E =b4 percentage points at the 95% coniidence level. For results based on the sample of 420 retirees, the margin of sampling error is :I:'? percentage points. For results based on the sample of 495 non-retirees, the margin of sampling error is :I:5 percentage points. Interviews are conducted with respondents on landline telephones and cellular phones, with interviews conducted in Spanish for respondents who are primarily Spanish-speaking.

Demographic weighting targets are based on the March 2017 Current Population Survey gures for the aged 18 and older U.S. population. Phone status targets are based on the January-June Ill]? National Health Interview Survey. Population density targets are based on the 2010 census. All reported margins of sampling error include the computed design effects for weighting
