HistoryA character grade: shown, never part of Pasadena’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 Pasadena’s 9.3 sits above most of its state (69% of Maryland towns have fewer) while its 32 historic buildings outnumber those of 82% 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 (±0.5 points) is firm at this size.
