Within each contacted household reached via landline, an interview is sought with an adult 18 years of age or older living in the household who has had the most recent birthday.

This is a method pollsters commonly use to make a random selection within households without having to ask the respondent to provide a complete roster of adults living in the household. Gallup does not use the same respondent selection procedure when making calls to cell phones because they are typically associated with one individual rather than shared among several members of a household.

When respondents to be interviewed are selected at random, every adult has an equal probability of falling into the sample. Gallup's Daily tracking process now allows Gallup analysts to aggregate larger groups of interviews for more detailed subgroup analysis.

Where population information is available, sample selection is based on probabilities proportional to population size; otherwise, Gallup uses simple random sampling. In countries where telephone interviewing is employed, Gallup uses a RDD method or a nationally representative list of phone numbers.

In select countries where cellphone penetration is high, Gallup uses a dual sampling frame. Gallup makes at least three attempts to reach a person in each household. Unless an outright refusal occurs, interviewers make up to three attempts to survey the sampled household.

To increase the probability of contact and completion, interviewers make attempts at different times of the day, and when possible, on different days. If the interviewer cannot obtain an interview at the initial sampled household, he or she uses a simple substitution method.
