How the AP-NORC poll on unity and division was conducted

The original sample was drawn from respondents selected randomly from NORC's National Frame based on address-based sampling and recruited by mail, email, telephone and face-to-face interviews.

No more than 1 time in 20 should chance variations in the sample cause the results to vary by more than plus or minus 4.1 percentage points from the answers that would be obtained if all adults in the U.S. were polled.
