At the beginning of recorded time, the area that we today call Tompkins County was home of the Cayugas, one of the five nations of the Haudenosaunee or the “People of the Longhouse,” also known as the Iroquois Confederacy.
In 1817, the State of New York approved the creation of Tompkins County with Ithaca as the county seat. The county was named for Daniel D. Tompkins, then governor of New York and soon to be vice president of the United States from 1817 until 1825.
As of the 2010 census, the population was 101,564 with the City of Ithaca still serving as the county seat. View more demographic information about Tompkins County.
