American football, under attack from critics in recent years, has lost some of its popularity but is still the champion of U.S. spectator sports -- picked by 37% of U.S. adults as their favorite sport to watch
Results for this Gallup poll are based on telephone interviews conducted Dec. 4-11, 2017, with a random sample of 1,049 adults, aged 18 and older, living in all 50 U.S. states and the District of Columbia. For results based on the total sample of national adults, the margin of sampling error is ±4 percentage points at the 95% confidence level. All reported margins of sampling error include computed design effects for weighting.
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. Landline and cellular telephone numbers are selected using random-digit-dial methods.
