Geography
Hagerstown–Martinsburg, MD–WV Metropolitan Statistical Area (MSA) covers an area of 1,019 square miles (2,640 km).
The MSA is roughly bordered to the east by South Mountain, to the west by Sideling Hill, to the north by the Mason–Dixon line, and to the south by Northern Virginia. Elevations run from about 250 feet (76 m) above sea level in low-lying valleys to approximately 1,250 feet (380 m) above sea level at Sideling Hill. The Potomac River runs from west to east through the heart of the metro area with tributaries including Sideling Hill Creek, Conococheague Creek, and Antietam Creek. Terrain in the region is very well-suited and used for dairy farming, cornfields, and fruit orchards. Some undeveloped deciduous forestry also exists, especially in the mountainous portions of the area. However, much of the region's land is becoming increasingly threatened by urban sprawl.
Hagerstown and Martinsburg are situated in the transition between the humid subtropical climate zone (Köppen Cfa) and the humid continental climate zone (Köppen Dfa), with hot, humid summers and cool to moderately cold winters where average annual snowfall is around 20 inches and temperatures below 15 °F (−9 °C) are annual occurrences.
Demographics
The metropolitan area's population in 2000 was 222,771. The 2008 estimate is 263,753, making Greater Hagerstown-Martinsburg the 169th largest metropolitan area in the United States. The growth rate from 2000 to 2008 is +18.4%, meaning that the metro area is the 48th fastest growing MSA (out of 363 total MSAs) in the entire country and the most rapidly growing in Maryland and West Virginia from 2000 to 2008. Metropolitan Hagerstown-Martinsburg also registered a higher net numerical population gain from 2006 to 2007 than Baltimore-Towson, MD MSA during the same time period. Much of the growth is due to the influx of people from Washington, D.C. and, to a lesser extent, Baltimore.
