City allegiance map

Every U.S. city is rooting for a different World Cup.

America, Canada, and Mexico host in 2026. But inside the U.S. it plays out as dozens of home tournaments at once. This maps where each national team's pull runs deepest, from Census place-of-birth and ancestry data. Click a city to see who it actually roots for.

When Argentina or Colombia play, Miami is a home crowd for both, plus the largest Haitian community in the country. Its two biggest flags, Cuba and Venezuela, did not qualify.

The most contested cities

Most contested is not most immigrants. It is the cities where the most national teams each have a real home crowd, with no single flag running away with it.

How this was built

  1. 1Start from Census place-of-birth and ancestry by metro: the largest national-origin communities in each city.
  2. 2Keep only communities whose national team qualified for the 2026 World Cup. That alone removes Cuba, the Dominican Republic, El Salvador, Poland, Italy, Nigeria, China, India, and more.
  3. 3Rank the remaining teams by community size, then score contested-ness 0-100: high means several qualified teams each have a real crowd.
  4. 4Diaspora is an allegiance signal, not a guarantee. Plenty of people root for the USMNT or no one.

Sources & caveats

  • —Allegiance is a signal from community size, not a measured count of fans.
  • —Only teams in the final 2026 field are included. A city's largest community is often not in it.
  • —Place-of-birth data undercounts 2nd and 3rd generation fans who still carry the flag.
