History grade
What drives Silver Spring’s History grade
On its age, its old homes and the National Register, Silver Spring is more historic than 55% of U.S. towns, #76 of 261 in Maryland. Its National Register listings hold the grade up; its age pulls it down.
B−
HistoryA character grade: shown, never part of Silver Spring’s overall grade.
Few Maryland towns list much on the Register (a typical Maryland town has 0.9 per 10,000 residents, the U.S. 2.4), so Silver Spring’s 3.6 sits near the middle of its state (59% of Maryland towns have fewer) while its 29 historic buildings outnumber those of 81% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to B+. The pre-1940 share (±1.1 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1887 falls in the same era, so the grade doesn’t depend on which one is used.
