Political Polarization and Typology Survey, 2014

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


The 2014 Pew Political Typology Survey, fielded for the Pew Research Center for the People & the Press by Abt SRBI, completed telephone interviews with a representative sample of 10,013 adults living in the United States (5,010 respondents were interviewed on a landline telephone and 5,003 were interviewed on a cell phone). Data collection was divided equally into three phases (A, B, and C) with non-overlapping field dates. Each third of the interviews was essentially treated as a separate study with separate samples, field dates, weighting and questionnaires, although some questions were asked throughout all three phases.

Data File
Cases: 10,013
Variables: 239
Weight Variable: LLWEIGHT CELLWGHT WEIGHT
Weights were computed at the completion of each phase of data collection. The final survey dataset contains three weight variables, including the original full sample weight (WEIGHT), a weight for respondents from the landline sample (LLWEIGHT), and a weight for respondents from the cell sample (CELLWGHT). At the Pew’s request, weights are computed for respondents who completed the entire interview (n=10,003) as well as those who completed most (but not all) of the interview and reported their ZIP Code (n=10). Two-stage weighting was used to correct for different probabilities of selection associated with the number of adults in the household and the respondent’s telephone usage, and balanced to match national population parameters for sex, age, education, race, Hispanic origin, region (U.S. Census definitions), population density and telephone usage.

Collection Procedures
Landline and cell phones numbers were called as many as seven times. Refusal conversion was attempted on soft refusal cases in both the landline and cell phone sample. 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. For the landline sample, interviewers asked to speak with either the youngest male or youngest female at home at the time of the call. For the cell sample, interviews were conducted with the person who answered the phone provided they were age 18 or older. 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 U.S. For each phase of data collection, new 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. All 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 through a systematic sampling from 1000-blocks dedicated to cellular service according to the Telcordia database.
