HistoryA character grade: shown, never part of Marlton’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 Marlton’s 2.0 sits near the middle of its state (53% of Maryland towns have fewer) while its 2 listings outnumber those of 60% 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 (±0.4 points) is firm at this size.

The story so far
Marlton, in brief
Wikipedia doesn’t have a history of Marlton yet. The photos, dates and memories neighbors add here are how it gets written.
Marlton is an unincorporated area and census-designated place (CDP) in Prince George's County, Maryland, United States. The population was 9,802 at the 2020 census. The Marlton housing development, at first briefly called "Brandywine Country", grew up along U.S. Route 301 in the 1970s, and is part of the greater Upper Marlboro community. Originally made up of only single-family homes, more recently townhouses have been added.
Between the 2010 and 2020 censuses its population grew from 9,031 to 9,802 (+9%).
