What drives Georgetown’s History grade

On its age, its old homes and the National Register, Georgetown is more historic than 77% of U.S. towns, #13 of 37 in Delaware. All 3 inputs are above most U.S. towns; its age ranks highest and its share of homes from before 1940 lowest.

A−
HistoryA character grade: shown, never part of Georgetown’s overall grade.

Delaware towns list more on the Register than most of the country (a typical Delaware town has 29.4 per 10,000 residents, the U.S. 2.4), so Georgetown’s 32.6 sits near the middle of its state (58% of Delaware towns have fewer) while its 25 historic buildings outnumber those of 81% of U.S. towns.

NoteThe founding year comes from Wikidata alone; no second source gives 1791.
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 (±11.1 points).

The story

How Georgetown came to be

From Wikipedia’s history of Georgetown.

Read it all →

Lewes, sited on the Delaware Bay, was designated as the first county seat. It was the first colony in Delaware, founded by the Dutch in 1631, and it remained the only significant European settlement in the region for some time. When English colonist William Penn organized the three southern counties of Pennsylvania, which are now Delaware, Lewes was the natural choice for the location of the Sussex County's Seat of Justice.
