Upper Marlboro, MD
Upper Marlboro wildfire risk explained
Out of every US place USFS scores, Upper Marlboro lands at the 38th percentile for wildfire risk to structures — close to the middle of USFS's national wildfire-risk range — a figure built from its 582 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Upper Marlboro at the 38th percentile, close to its 38th-percentile risk score.
What "at risk" means for the buildings here
Most of Upper Marlboro's buildings (66.2%) sit in the Indirect zone, where wind-blown embers rather than flame front are the mechanism USFS is scoring — ember-resistant vents and non-combustible roofing are the interventions this pattern favors, more than defensible space alone.
How Upper Marlboro compares
Within Maryland, Upper Marlboro ranks higher (57th percentile) than it does nationally (38th) — one of the more fire-exposed places in a state that, overall, scores lower than that. Among the 31,521 US communities USFS scores, Upper Marlboro ranks 19,536 for wildfire risk (1 is highest) and 16,079 by building count (1 is largest). Within Maryland alone, it ranks 229 of 527 places by risk. See the full county-by-county picture for Maryland on its state page.
What this risk score means for insurance
Upper Marlboro's moderate rating (38th percentile nationally) sits outside the range where wildfire risk alone reshapes an insurance market — still, a homeowner here loses nothing by comparing rates.

More on how this number was built
Upper Marlboro's 38th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what indirect exposure implies beyond Upper Marlboro, see the exposure-zones guide.
