- The NBA has the youngest audience, with 45 percent of its viewers under 35. It also has the highest share of black viewers, at 45 percent—three times higher than the NFL or NCAA basketball.
- Major League Baseball shares the most male-heavy audience, at 70 percent, with the NBA.
- The NHL audience is the richest of all professional sports. One-third of its viewers make more than $100k, compared to about 19 percent of the general population.
- Nascar’s audience has the highest share of women (37 percent) and highest share of white people (94 percent).
- The Professional Golfers Association has the oldest audience by multiple measures: smallest share of teenagers; smallest share of 20- and early 30-somethings; and highest share of 55+ (twice as high, in the oldest demo, as the NBA or Major League Soccer).
- Major League Soccer has the highest share of Hispanics by far (34 percent; second is the NBA at 12 percent) and the lowest income of any major sports audience. Nearly 40 percent of its fans make less than $40k.
- The NCAA demographics for football and basketball are practically identical but they are surprising old (about 40% over 55+) and surprisingly white (about 80%), which clearly has as much to do with who owns a TV rather than who follows the sports.
There are much smaller demographic differences – say across gender as all of these sports have primarily male viewers – and larger ones, particularly across race and ethnicity, income, and race.
I wonder if this could all be easily deduced by watching the commercials that play during the games. While the average fan may not be aware of these demographic splits, advertisers most certainly are and target the audience accordingly. Yet, I can’t say I quickly can name notable advertisement differences between the NFL, NBA, MLB, and NHL off the top of my head in the same way I quickly notice a difference in advertisements when turning on the network news at night (a very rare occurrence).
