The Associated Press-NORC Center for Public Affairs Research and MTV Youth Political Pulse poll of young Americans was conducted by NORC from April 23 to May 9 using NORC's AmeriSpeak Panel. It is based on online and telephone interviews of 558 young people ages 15 to 26 who will be old enough to vote in the 2020 election, and 607 parents of teens and young adults in that age group.
To select teens ages 15 to 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 one time in 20 should chance variations in the sample cause the results to vary by more than plus or minus 5.6 percentage points from the answers that would be obtained if all young Americans ages 15 to 26 in the U.S. were polled, or by more than plus or minus 6.7 percentage points for their parents.
There are other sources of potential error in polls, including the wording and order of questions.
