About Erie County

Erie County is a large urban county along the shore of Lake Erie in the western region of the U.S. state of New York, and the most populated county in New York State outside of the NYC Metro. As of the 2020 census, the population was 954,236. In 2025 the estimated population was 946,741. The county seat is Buffalo, which makes up about 28% of the county's population. Both the county and Lake Erie were named for the Indigenous Iroquoian language-speaking Erie people, who lived in the area before 1654. They were later pushed out or assimilated by the neighboring Haudenosaunee (Iroquois) during the Beaver Wars. The county is part of the Western New York region of the state.

Background

History of Erie County

When counties were established by the English colonial authorities in the Province of New York in 1683, present-day Erie County was inhabited by the Haudenosaunee. Significant colonization by White Americans did not begin until after the United States had gained independence with the end of the American Revolutionary War in 1783. The U.S. forced the Haudenosaunee to cede most of their lands, as many had been allies of the British during the conflict. About 1800, the Holland Land Company, formed by American businessmen and their Dutch associates, extinguished aboriginal claims by purchasing the land from New York, acquired the title to the territory of what are today the eight westernmost counties of New York, surveyed their holdings, established towns and began selling lots to individuals. The state was eager to attract settlers and have homesteads and businesses developed.
