HistoryA character grade: shown, never part of Fairfield’s overall grade.
Wisconsin towns list more on the Register than most of the country (a typical Wisconsin town has 3.0 per 10,000 residents, the U.S. 2.4), so Fairfield’s 8.6 sits above most of its state (74% of Wisconsin towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±4.7 points).

What stands out about Fairfield’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The town is the location of the "sand farm" (Aldo Leopold Shack and Farm) purchased by Aldo Leopold in 1935. A family retreat from the city of Madison, Leopold's attempts to restore health to this abandoned farm, with the help of family and friends, became the inspiration for his masterpiece, "A Sand County Almanac." Leopold died near 'the Shack' while fighting a neighbor's grass fire in 1948.
