Religion and Politics Survey, January 2016

Data Archive > U.S. Surveys > General Population > National > Pew Research Center > Summary

The January 2016 Political Survey, fielded for the Pew Research Center for the People & the Press by Abt SRBI, obtained telephone interviews with a representative sample of 2,009 adults living in the United States (504 respondents were interviewed on a landline telephone and 1,505 were interviewed on a cell phone). Interviewing was conducted from January 7th to 14th, 2016 in English and Spanish. Samples were drawn from both the landline and cell phone RDD frames. Persons with residential landlines were not screened out of the cell phone sample. Both the landline and cell phone samples were provided by Survey Sampling International. The combined sample is weighted to match demographic parameters from the American Community Survey and telephone status parameters from the National Health Interview Survey. The weighting procedure also accounts for the fact that respondents with both a landline and cell phone had a greater probability of selection. The margin of sampling error for weighted estimates based on the full sample is 2.46 percentage points.

Collection Procedures
Landline numbers were called as many as 7 times, and cell phone numbers were called as many as 7 times. Refusal conversion was attempted on soft refusal cases. Interviews were conducted from January 7-14, 2016. Calls were staggered over times of day and days of the week to maximize the chance of making contact with potential respondents. Each number received at least one daytime call. The sample was released for interviewing in replicates, which are representative subsamples of the larger sample. Using replicates to control the release of sample ensures that complete call procedures are followed for the entire sample.

For the landline sample, interviewers asked to speak with either the youngest male or youngest female at home right now. For the cell sample, interviews were conducted with the person who answered the phone. Interviewers verified that the person was an adult and in a safe place before administering the survey. Cell sample respondents were offered a post-paid cash incentive of $5 for their participation.
Sampling Procedures
The target population for the study is non-institutionalized persons age 18 and over, living in the US. Samples were drawn from both the landline and cellular random digit dial (RDD) frames to represent people with access to either a landline or cell phone. Both samples were provided by Survey Sampling International, LLC according to Abt SRBI specifications.

Numbers for the landline sample were drawn with equal probabilities from active blocks (area code + exchange + two-digit block number) that contained one or more residential directory listings. The cellular sample was drawn by Survey Sampling International through a systematic sampling from 1000-blocks dedicated to cellular service according to the Telcordia database.
