A nation counts for a given year if at least one rider with that nationality participated in a race of that class. Race tiers follow the UCI classification system.
The globalization trend shows how international mountain bike racing has become at every tier of the UCI calendar. For each UCI class code (Olympic Games, World Championships, World Cup, Continental Championships, Hors Class, Class 1/2/3, etc.) we plot the number of different nations represented per year. Together, the charts paint a picture of how the sport has expanded geographically since 2009.
Each chart is one race tier. The bar height is the count of distinct nations participating that year. A nation counts if at least one rider with that nationality started a race of that class. Reading them top to bottom — Olympic Games at the top, Test Events at the bottom — gives you a sense of how globalization differs by tier: top-tier events tend to attract a stable, broad set of nations, while developmental tiers are where you spot expansion (or contraction).
Globalization is a key health indicator for any sport. A growing number of participating nations at the World Cup or World Championships means the sport is reaching new markets; a flat or shrinking count at the entry tiers may flag stagnation in grassroots development.
