Twenty-eight percent of adults get into the fun at least some years by filling out a men’s or women’s tournament bracket through formal or informal betting pools. About a quarter of adults fill out a bracket for the men’s tournament every year or some years and 16% do so for the women’s tournament. A larger share of younger adults are avid participants in March Madness pools with 30% of those under 45 filling out a men’s bracket at least some years compared with 23% of older adults.
