How Does the Gallup U.S. Daily Work?

Continuously Tracks Americans' Views on Political and Economic Issues

What is the Gallup U.S. Daily?

The Gallup U.S. Daily, which began in 2008 as part of the Gallup Daily tracking survey, takes the pulse of the nation. It gauges Americans' opinions and perceptions of the most pressing political and economic issues and the current events that affect the world, the U.S., and their lives. The Gallup U.S. Daily data provide a reliable source of intelligence in a changing world and assist leaders in answering the questions that they care about most. The survey's large sample sizes -- 3,500 after a week, 15,000 after a month, and 175,000 after a year -- allow Gallup to look at extensive demographic breaks and cross-tabulations of the daily measures.

Gallup routinely incorporates additional questions into the Gallup U.S. Daily survey on a short-term basis. These extra questions cover topical issues, including Americans' election voting intentions and views of events in the news.

How are interviews conducted for the Gallup U.S. Daily?

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 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 50% cellphone respondents and 50% 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 U.S. Daily?

Gallup interviews approximately 500 U.S. adults ages 18 and older through the Gallup U.S. Daily.

How often are the Gallup U.S. Daily interviews conducted?

Since the U.S. Daily began in 2008, Gallup has been conducting the survey every day, excluding major holidays and other events, for 350 days per year.

Are the Gallup U.S. Daily 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. as a whole and individual 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.
