Key Gallup Surveys
The Gallup Poll Social Series includes topical questions on political, economic, and social issues and several hundred long-standing Gallup trends -- some dating back to the 1930s. Gallup initiates these surveys during the same month every year and includes a survey's core trend questions in the same order each administration. Using this consistent standard allows Gallup researchers to reliably analyze changes in trend data.
The Gallup World Poll monitors the issues that matter most to societies worldwide, such as personal safety, food and shelter, employment, well-being, and confidence in national institutions. This survey is administered face to face or by telephone in more than 160 countries and areas and in over 140 languages.
The Gallup National Health and Well-Being Index includes the most precise data available on Americans' health conditions and behaviors. The Well-Being Index measures Americans' perceptions of their lives and daily experiences, capturing the interrelated elements that make up well-being, including having a natural right fit in your life, social relationships, financial security, relationship to the community and physical and mental health.
The Gallup U.S. Daily Tracking Poll gauged Americans' opinions on and perceptions of pressing political and economic issues and current events from 2008 to 2017.
In addition to our core polls, organizations worldwide turn to Gallup to conduct custom surveys using our rigorous research standards and scientifically proven methodologies to help them solve their most pressing problems.
