On its age, its old homes and the National Register, Delavan is more historic than 67% of U.S. towns, #135 of 362 in Wisconsin. All 2 inputs are above most U.S. towns; its National Register listings ranks highest and its share of homes from before 1940 lowest.

From Wikipedia’s history of Delavan.
Delavan sits in the middle of what was once an inland sea. During the last ice age, the final glaciation, named the Michigan tongue, covered this region. The Michigan tongue descended along the area of Lake Michigan. The "Delavan lobe" of this glacier broke off, pushing southwest into the area of Walworth County.

The second charitable institution incorporated by the State was the " Wisconsin Institute for the Education of the Deaf and Dumb." It was originally a private school for deaf mutes, near, and subsequently in, the village of Delavan, Walworth county. By an act of the legislature approved April 19, 1852, it was made the object and duty of the corporation to establish, continue and maintain this school for the education of the deaf and dumb, "at or near the village of Delavan, to qualify, as near as might be, that unfortunate class of persons for the enjoyment of the blessings of a free government, obtaining the means of subsistence, and the discharge of those duties, social and political, devolving upon American citizens."

Each neighbor’s History grade, on the same three inputs.
Delavan is more historic than 67% of U.S. towns, #135 of 362 in Wisconsin. The History grade combines the town’s founding era, the share of homes built before 1940 and its National Register listings. It’s a character grade, so it isn’t part of the overall grade. How it works.
Two places: the Fred B. Jones Estate (listed 1974) and the A.P. Johnson House (1982).
11% of Delavan’s homes were built before 1940 (Census estimate, ±3.5 points), against a typical 12% for a Wisconsin town; the median home was built in 1973.
