Millennials and Political News


This report is part of a series by the Pew Research Center aimed at understanding of political news and information habits in the American public. An initial report on these data explored these habits across the ideological spectrum. Data in this report are drawn from the first wave of the Pew Research Center’s American Trends Panel, conducted March 19 to April 29, 2014, among 2,901 Web respondents. The panel was recruited from a nationally representative survey, which was conducted by the Pew Research Center in early 2014 and funded in part by grants from the William and Flora Hewlett Foundation and the John D. and Catherine T. MacArthur Foundation and the generosity of Don C. and Jeane M. Bertsch.

The data in this report is based on a nationally representative group of respondents who were recruited from the Center’s largest survey on domestic politics to date: the 2014 Political Polarization and Typology Survey, a telephone survey of more than 10,000 Americans. A subset of these respondents was impaneled into the American Trends Panel (ATP) and most of the analysis in the report is based on the first wave of the ATP, a survey conducted by Web and telephone. As with the American public overall, the vast majority of panel members has Web access and has opted to take the surveys online. Indeed, data from the survey from which the American Trends Panel was recruited show that as of March 2014, 89% of American adults use the Internet. Similarly, 88% of this Wave 1 of the American Trends Panel completed the survey online.6 This report is based only on the respondents who completed the survey online.

About the American Trends Panel

The American Trends Panel (ATP), created by the Pew Research Center, is a nationally representative panel of randomly selected U.S. adults living in households. Respondents who self-identify as internet users (representing 89% of U.S. adults) participate in the panel via monthly self-administered Web surveys, and those who do not use the internet participate via telephone or mail. The panel is being managed by Abt SRBI.

Data in this report are drawn from the first wave of the panel, conducted March 19 to April 29, 2014 among 2,901 Web respondents. The margin of sampling error for the Web sample of 2,901 respondents is plus or minus 2.3 percentage points.

All current members of the American Trends Panel were originally recruited from the 2014 Political Polarization and Typology Survey, a large (n=10,013) national landline and cellphone random digit dial (RDD) survey conducted Jan. 23 to March 16, 2014, in English and Spanish. At the end of that survey, respondents were invited to join the panel. The invitation was extended to all respondents who use the internet (from any location) and a random subsample of respondents who do not use the internet.7

Of the 10,013 adults interviewed, 9,809 were invited to take part in the panel. A total of 5,338 agreed to participate and provided either a mailing address or an email address to which a welcome packet, a monetary incentive and future survey invitations could be sent. Panelists also receive a small monetary incentive after participating in each wave of the survey.

The ATP data were weighted in a multi-step process that begins with a base weight incorporating the respondents’ original survey selection probability and the fact that some panelists were subsampled for invitation to the panel. Next, an adjustment was made for the fact that the propensity to join the panel varied across different groups in the sample. The final step in the weighting uses an iterative technique that matches gender, age, education, race, Hispanic origin and region to parameters from the U.S. Census Bureau’s 2012 American Community Survey. Population density is weighted to match the 2010 U.S. Decennial Census. Telephone service is weighted to estimates of telephone coverage for 2014 that were projected from the January-June 2013 National Health Interview Survey.  It also adjusts for party affiliation using an average of the three most recent Pew Research Center general public telephone surveys, and for internet use using as a parameter a measure from the 2014 Survey of Political Polarization. Sampling errors and statistical tests of significance take into account the effect of weighting. The Hispanic sample in the American Trends Panel is predominantly native born and English speaking. In addition to sampling error, one should bear in mind that question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of opinion polls.

The Web component of the first wave had a response rate of 61% (2,901 responses among 4,753 Web-based individuals enrolled in the panel. Taking account of the response rate for the 2014 Survey of Political Polarization (10.6%), the cumulative response rate for the first ATP wave is 3.6%.

The accompanying table shows the unweighted sample sizes and the error attributable to sampling that would be expected at the 95% level of confidence for selected groups discussed in the report.

  1. This percentage of wave 1 panel members who completed the survey online is unweighted; the figure is 81% if weighted.
  2. When data collection for the 2014 Political Polarization and Typology Survey began, non-internet users were subsampled at a rate of 25%, but a decision was made shortly thereafter to invite all non-internet users to join. In total, 83% of non-internet users were invited to join the panel.
