Maps and Data
The Tompkins County Department of Planning and Sustainability maintains a Geographic Information System (GIS) that collects, maintains, and prepares maps of geographic data. Most of the Department's GIS function is centered on data that support the Department's ongoing planning activities. As a result, the Department of Planning and Sustainability produces a variety of maps for use by the general public. The maps are intended for citizen planners and the general public to help them plan in their communities.
Custom maps, analysis, and data services are offered by County GIS analysts by appointment.

US Census Data
American Community Survey
The American Community Survey (ACS) is an ongoing survey that provides detailed information about our community. It collects data on social, housing, and economic characteristics every year, offering a more up-to-date picture than the traditional decennial census. The ACS provides estimates for various geographic areas, including Tompkins County. For smaller areas, like census tracts and block groups, the ACS accumulates data over three- and five-year intervals to deliver reliable estimates.
Decennial Census of Population and Housing
The U.S. Census Bureau conducts a population count every 10 years. This data provides a valuable snapshot of our community at that specific time.
