A new study claims it's harder to play Pokémon Go in DC.'s black neighborhoods in comparison to its white ones.

The Urban Institute conducted the study. It found that PokéStops and Pokémon gyms were more commonly found in predominantly white neighborhoods.

The maker of Pokémon Go, Niantic, did not reveal its geographic data to the Urban Institute. But the researchers were able to figure out where PokéStops were located by examining an older Niantic game called Ingress.

Both Ingress and Pokémon Go are based off the same database. In Ingress, players could make suggestions to developers where to locate "portals," an aspect of that game similar to a PokéStop.

Those portals were typically found in business and tourist areas.

"Because Ingress players tended to be younger, English-speaking men, and because Ingress's portal criteria biased business districts and tourist areas, it is unsurprising that portals ended up in white-majority neighborhoods," the study said.

WUSA9 reached out to Niantic, but did not receive a reply.
