Continuously Monitors Americans' Attitudes and Behaviors
What is the Gallup Daily tracking survey?
The Gallup Daily tracking survey, which began in 2008, is an unprecedented survey of approximately 1,000 U.S. adults each day, 350 days per year. Gallup Daily tracking consists of two parallel surveys: the U.S. Daily and the Gallup-Sharecare Well-Being Index. For each of the two surveys, large sample sizes -- 3,500 after a week, 15,000 after a month, and 175,000 after a year -- allow Gallup to examine extensive demographic breaks and cross-tabulations of the daily measures.
Gallup routinely incorporates additional questions into the Gallup Daily tracking survey on a short-term basis. These extra questions cover topical issues, including Americans' election voting intentions and opinions on worldwide news.
How are interviews conducted for the Gallup Daily tracking survey?
Gallup interviews U.S. adults aged 18 and older living in all 50 states and the District of Columbia using a dual-frame design, which includes both landline and cellphone numbers. Gallup samples landline and cellphone numbers using random-digit-dial methods. Gallup purchases samples for this study from Survey Sampling International (SSI). Gallup chooses landline respondents at random within each household based on which member had the next birthday. Each sample of national adults includes a minimum quota of 70% cellphone respondents and 30% landline respondents, with additional minimum quotas by time zone within region. Gallup conducts interviews in Spanish for respondents who are primarily Spanish-speaking.
How many people are interviewed as part of the Gallup Daily tracking survey?
Gallup interviews approximately 1,000 U.S. adults aged 18 and older every day. Of the 1,000 adults, Gallup interviews approximately 500 respondents through the U.S. Daily survey and approximately 500 respondents through the Gallup-Sharecare Well-Being Index survey.
How often are the Gallup Daily tracking survey interviews conducted?
Since Gallup Daily tracking began in 2008, Gallup has been conducting interviews every day, excluding major holidays and other events, for 350 days per year.
Are the Gallup Daily tracking samples weighted?
Yes, Gallup weights samples to correct for unequal selection probability, nonresponse, and double coverage of landline and cellphone users in the two sampling frames. Gallup also weights its final samples to match the U.S. population according to gender, age, race, Hispanic ethnicity, education, region, population density, and phone status (cellphone only, landline only, both, and cellphone mostly). Demographic weighting targets for the U.S. and states are based on the most recent Current Population Survey figures for the aged 18 and older U.S. population, while weighting targets for metropolitan areas and congressional districts are based on Nielsen Claritas statistics. Phone status targets are based on the most recent National Health Interview Survey. Population density targets are based on the most recent U.S. Census. All reported margins of sampling error include computed design effects for weighting.
