The counties of Erie and Niagara exhibit significant inequalities in household income across their communities. High-income enclaves in East Amherst, Clarence, Orchard Park, East Aurora, and the City of Buffalo are contrasted against entrenched poverty and a persistent underclass in the inner-cities of Buffalo and Niagara Falls, as well as in outlying rural towns. Median incomes levels, as well as the absolute and relative levels of poverty and wealth, are presented by zip code.
