ACA at Age 4: More Disapproval than Approval

But Most Opponents Want Politicians to Make Law Work

About the Surveys

Most of the analysis in this report is based on telephone interviews conducted Feb.27-Mar. 16, 2014 among a national sample of 3,335 adults, 18 years of age or older, living in all 50 U.S. states and the District of Columbia (1,668 respondents were interviewed on a landline telephone, and 1,667 were interviewed on a cell phone, including 870 who had no landline telephone). The survey was conducted under the direction of Abt SRBI. A combination of landline and cell phone random digit dial samples were used; both samples were provided by Survey Sampling International. Interviews were conducted in English and Spanish. Respondents in the landline sample were selected by randomly asking for the youngest adult male or female who is now at home. Interviews in the cell sample were conducted with the person who answered the phone, if that person was an adult 18 years of age or older.

The combined landline and cell phone sample are weighted using an iterative technique that matches gender, age, education, race, Hispanic origin and nativity and region to parameters from the 2012 Census Bureau’s American Community Survey and population density to parameters from the Decennial Census. The sample also is weighted to match current patterns of telephone status and relative usage of landline and cell phones (for those with both), based on extrapolations from the 2013 National Health Interview Survey. The weighting procedure also accounts for the fact that respondents with both landline and cell phones have a greater probability of being included in the combined sample and adjusts for household size among respondents with a landline phone. Sampling errors and statistical tests of significance take into account the effect of weighting.

The following table shows the unweighted sample sizes and the error attributable to sampling that would be expected at the 95% level of confidence for different groups in the survey:

Sample sizes and sampling errors for other subgroups are available upon request. 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.

Some of the analysis in this report is based on telephone interviews conducted Jan. 23-Feb. 9, 2014 among a national sample of 3,341 adults, 18 years of age or older, living in all 50 U.S. states and the District of Columbia (1,671 respondents were interviewed on a landline telephone, and 1,670 were interviewed on a cell phone, including 875 who had no landline telephone).

The news interest data in this report is based on telephone interviews conducted Mar. 6-9, 2014 among a national sample of 1,003 adults, 18 years of age or older, living in all 50 U.S. states and the District of Columbia (501 respondents were interviewed on a landline telephone, and 502 were interviewed on a cell phone, including 280 who had no landline telephone). The survey was conducted by interviewers at Princeton Data Source under the direction of Princeton Survey Research Associates International. A combination of landline and cell phone random digit dial samples were used; both samples were provided by Survey Sampling International. Interviews were conducted in English and Spanish. Respondents in the landline sample were selected by randomly asking for the youngest adult male or female who is now at home. Interviews in the cell sample were conducted with the person who answered the phone, if that person was an adult 18 years of age or older.
