GPT-3.5 is significantly worse with facts than GPT-4, by the way. GPT-3.5 hallucinates a lot, GPT-4, notably, is accurate enough to pass many common exams.

Explanation:
1. Wisconsin is a state in the northern part of the Central United States (not western).
2. As of 2021, Wisconsin was the 23rd largest state by total area and the 20th most populous, but this may have changed by 2023.
3. The borders of Wisconsin are correctly described.
4. The bulk of Wisconsin's population is not along the shores of Lake Superior, but is more densely populated in the southeastern part of the state.
5. Milwaukee is the largest city in Wisconsin, not Madison. Madison is the second largest, followed by Green Bay.
6. Madison may be the second-most-populated and fastest-growing city in Wisconsin, but this requires updated data beyond 2021 to confirm.
7. Wisconsin is divided into 72 counties, not 71. As of the 2020 census, Wisconsin had a population of over 5.8 million, not 2.9 million.
