Ontario County, first organized in 1789, is situated southeast of Rochester. Much of Canandaigua Lake and the northwest shore of Seneca Lake are located in Ontario County. Ontario is the second most populous county in the region after Monroe with just under 110,000 residents in 2016.
With a 9.6% increase in residents from 2000 to 2016, Ontario County is one of only two counties in the region (along with Seneca) to boast significant population growth. Ontario has a strong tourism sector, anchored by the high-end Eastview Mall, CMAC Performing Arts Center, and several wineries and breweries.
It also has the highest median income and home values in the region, along with the lowest poverty rate. Almost a third of residents hold a bachelor’s degree or higher, and the county has the lowest share of the adult population receiving less than a high school diploma in the region.
