NBC News and the Commonwealth Fund will be polling likely U.S. voters throughout this election season about their thoughts on health care and the presidential candidates. Stay tuned to see how their views evolve.
How We Conducted This Study
The NBC News/Commonwealth Fund Health Care Poll was conducted by SSRS from January 28 through February 16, 2020. The survey consisted of telephone interviews conducted among a random, nationally representative sample of 2,303 adults, age 18 and older, living in the United States, and included an oversample of African Americans and Hispanics. Overall, 686 interviews were completed via landline and 1,617 were conducted via mobile phone. For this analysis, the sample population was limited to adults who reported they would definitely vote in the 2020 presidential election (“likely voter”). The final sample size among likely voters was 1,594.
This is the first poll in a series to track public sentiment on a range of health care issues during the 2020 presidential election season. Data were collected through the SSRS Omnibus. The SSRS Omnibus uses a fully-replicated, stratified, single-stage, random-digit-dialing (RDD) sample of telephone households, and randomly generated cell phones.
Each SSRS Omnibus insert was weighted to provide nationally representative and projectable estimates of the adult population 18 years of age and older. The weighting process took into account the disproportionate probabilities of household and respondent selection because of the number of separate telephone landlines and cell phones answered by respondents and their households, as well as the probability associated with the random selection of an individual household member. The sample was poststratified and balanced by key demographics such as age, race, sex, region, and education. The sample was also weighted to reflect the distribution of phone usage in the general population, meaning the proportion of those who are cell phone only, landline only, and mixed users. The weighting procedures adjusted for the oversampling of African American and Hispanic respondents.
The margin of error is +/– 2.4 percentage points at the 95 percent confidence level. The landline portion of the survey achieved a 5.4 percent response rate and the cellular phone component achieved a 3.1 percent response rate. The overall response rate was 3.8 percent.
