The Associated Press-NORC Center for Public Affairs Research and MTV Youth Political Pulse poll of young Americans was conducted by NORC from Feb. 22-March 9 using NORC's Amerispeak Panel. It is based on online and telephone interviews of 1,027 teens and young adults age 15-34 who will be old enough to vote in the 2020 election.
To select teens between age 15-17, adult panel members with children in that age group were selected from the panel and asked for permission to interview their teenager.
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.
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 and Spanish.
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, education, region 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 4.2 percentage points from the answers that would be obtained if all young Americans age 15-34 in the U.S. were polled.
There are other sources of potential error in polls, including the wording and order of questions.
