What drives Cairo’s History grade
On its age, its old homes and the National Register, Cairo is more historic than 98% of U.S. towns. All 3 inputs are above most U.S. towns; its National Register listings ranks highest and its age lowest.
A+
HistoryA character grade: shown, never part of Cairo’s overall grade.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Cairo’s 3,924 sits above most of its state (100% of Illinois towns have fewer) while its 660 historic buildings outnumber those of 98% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A to A+. The pre-1940 share is a Census survey estimate (±8.9 points). Two sources give 1818.

Fire insurance maps drew every building, what it was made of and what it was used for, so insurers could price the risk of fire. Pick a year, then a sheet.
Cairo was named after the Egyptian city of the same name because its location at the confluence of the Ohio and Mississippi Rivers was reminiscent of the Nile Delta.
The first municipal charter for Cairo and the Bank of Cairo were issued in 1818, but without any settlement and without any depositors. A second and successful effort to establish a town was made by the Cairo City and Canal Company in 1836–37, with a large levee built to encircle the site. However, this effort collapsed in 1840, with few settlers remaining.

The road was finished to Columbus, Kentucky, twenty miles south of Cairo, two or three or more years after the Central was finished to Cairo. The congressional land grant of September 20, 1850, was to aid in building a railroad from Chicago to Mobile, and these two railroad companies, the Central and the Mobile & Ohio, were to receive and did receive the benefits of that act; and there was, therefore, some two or three years before the Civil War a railroad from Chicago to Mobile, with the exception of the gap of twenty miles between Cairo
