Gallup takes several steps to draw a representative sample of the population: they use dual-frame random-digit-dial sampling that includes cell phones; they follow a random selection method to choose one respondent within a household; and they provide Spanish-language interviewers for respondents who speak only Spanish. Gallup also provides sample weights to compensate for disproportionalities in selection probabilities and non-response,so that the weighted sample matches the national distribution in terms of age, sex, region, gender, education and race. We utilize the sample weights in all of our analyses.
