Denver has 78 statistical neighborhoods. Statistical neighborhoods were established in 1970 by the city with the help of the Denver Regional Council of Governments (DRCOG). Statistical neighborhoods are largely consistent with U.S. Census tracts, and, like census tracts, the boundaries collectively cover the entire city and do not overlap.
Neighborhood organizations that register with the city are permitted to choose their own boundaries. Some RNOs choose boundaries that are consistent with statistical neighborhood boundaries, but many do not. RNO boundaries often overlap each other and cover multiple statistical neighborhoods. In many cases a statistical neighborhood is represented by multiple RNOs.
