What drives Jefferson’s History grade
On its age, its old homes and the National Register, Jefferson is more historic than 71% of U.S. towns, #68 of 140 in Iowa. Its share of homes from before 1940 holds the grade up; its age pulls it down.
B+
HistoryA character grade: shown, never part of Jefferson’s overall grade.
Iowa towns list more on the Register than most of the country (a typical Iowa town has 9.1 per 10,000 residents, the U.S. 2.4), so Jefferson’s 16.9 sits above most of its state (67% of Iowa towns have fewer) while its 7 historic buildings outnumber those of 73% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B− to A−. The pre-1940 share is a Census survey estimate (±6.6 points). The founding year is the first post office, not a stated founding date.

While platted and settled a few years earlier, "New Jefferson" was organized in the winter of 1855–56 and officially incorporated in January 1872. It began as a farming community and remains so today. The first settlers of the new city were the family of George S. Walton who built there in 1855. During the Civil War, Jefferson as well as Greene County contributed its sons to raising Company H, 10th Iowa Infantry (1861) and Company E, 39th Iowa Infantry (1862). The railway came to Jefferson in the decades after the Civil War. Jefferson's first mayor was Mahlon Head, elected in 1872. Jefferson's library was completed in 1904 through the generosity of the Carnegie library fund. The stretch of Lincoln Highway that runs through Jefferson was completed c. 1924.

Jefferson County appears to have been always remarkably free from the blighting influence of such lawless characters ; and, if the court records are to be taken in evidence, it may be stated as a fact that the moral character of the people, from the date of the first settlement, in 1836, to the present time, is unsurpassed by any other county in the State. Tiiere have been crimes, but, as a rule, they have been of the minor grades. So generally law-abiding were the people, that two years passed after the county was organized before any steps were taken to secure the erection of a jail. Nor do the records show any
