According to the Census Bureau records through 2007, Peoria Heights lies in three counties (Peoria, Woodford, and Tazewell). While neither Tazewell nor Woodford counties consider Peoria Heights to be within their jurisdiction, the state of Illinois does show that across Peoria Lake from the rest of the village, a small, uninhabited area exists both within Peoria Heights and Woodford County. However, the Census Bureau claim that Peoria Heights is also within Tazewell County is unsupported by any state, county, or municipal websites.
