How the AP-NORC poll of teenagers was conducted

The Associated Press-NORC Center for Public Affairs Research poll on teens and politics was conducted by NORC Dec. 7-31, 2016. It is based on online and telephone interviews of 790 teenagers whose parents are members of NORC's nationally representative AmeriSpeak panel.

The original sample was drawn among parents of teenagers selected randomly from NORC's National Frame based on address-based sampling and recruited by mail, email, telephone and face-to-face interviews. Parents were then asked for permission to interview their teenage children.

NORC interviews participants over the phone if they don't have internet access. With a probability basis and coverage of people who can't access the internet, surveys using AmeriSpeak are nationally representative.

Interviews were conducted in English.

As is done routinely in surveys, results were weighted, or adjusted, to ensure that responses accurately reflect the population's makeup by factors such as age, sex, race, region, household income and phone use.

No more than 1 time in 20 should chance variations in the sample cause the results to vary by more than plus or minus 4.6 percentage points from the answers that would be obtained if all teens in the U.S. were polled.

There are other sources of potential error in polls, including the wording and order of questions.
