Montgomery County is a county located in the U.S. state of Pennsylvania, in the United States. As of 2010, the population was 801,543, making it the third most populous county in Pennsylvania (after Philadelphia and Allegheny counties). The county seat is Norristown.

The county was created on September 10, 1784, out of land originally part of Philadelphia County. It is believed to have been either named in honor of Richard Montgomery, an American Revolutionary War general killed in 1775 while attempting to capture Quebec City, Canada, or for the Welsh county of Montgomeryshire (which was named after one of William the Conqueror's main counselors, Roger de Montgomerie), as it was part of the Welsh Tract, an area of Pennsylvania settled by Quakers from Wales. Early histories of the county indicate the origin of the county's name as uncertain.

Montgomery County is a suburban county northwest of Philadelphia. It is part of the Delaware Valley and marks the region's northern border with the Lehigh Valley region of the state. It is the 20th wealthiest county in the country (measured by personal per-capita income) and was named the 9th Best Place to Raise a Family by Forbes.[1]

Montgomery County is a suburb of Philadelphia and consequently, many of its residents work in the city. However, Montco is also a major employment center with large business parks in Blue Bell, Lansdale, Fort Washington, Horsham and King of Prussia which attract thousands of workers from all over the region. The strong job base and taxes generated by those jobs have resulted in Montgomery County receiving the highest credit rating of 'AAA' from Standard & Poor's, one of fewer than 30 counties in the United States with such a rating.

Major employers include:

Population growthEdit

Montgomery County's population grew about 10.6% as of the 2000 census with much of the growth in the western part of the county. Much of the growth is attributable to population shifts in the region. The county especially saw an increase of Asian American immigrants [5] as well as in Mexican immigrants. Also, Montgomery County receives a large amount of immigrants, and many migrants from other urban areas, looking for cheaper real estate compared to their areas. Montgomery County provides many expressways to Philadelphia, New Jersey, and many other places in Pennsylvania. Census Bureau projections show a slowing of the growth this decade. Part of the slowing of the growth is attributed to the massive emigration of native born residents.

While Republicans have dominated county politics, the Democratic Party has made substantial gains in the county over the last 20 years and gained the registration edge early in 2008. After voting for the Republican Presidential nominee for six consecutive elections from 1968 to 1988, the Democratic Presidential nominee has carried Montgomery for the past five consecutive elections by progressively increasing margins. Most county-level offices were held by Republicans until after the 2007 election, when Democrats picked up control of five row offices. Democrats have also won significant elections for the Pennsylvania General Assembly in recent years, including two GOP-leaning State House districts in 2004, the 148th with Mike Gerber and the 153rd with Josh Shapiro.

In the 2004 US Senate election, Republican Arlen Specter won the county over Montco resident Joe Hoeffel, but Democrat Bob Casey, Jr. out-polled Rick Santorum in the 2006 Senate election. In 2006, Democrat Rick Taylor unseated incumbent Republican Eugene McGill in the 151st and, in 2008, Democrat Matthew Bradford unseated incumbent Republican Jay Moyer in the 70th. Six out of twelve of the 12 Montgomery State Representative seats are now held by Democrats, but Daylin Leach is the only Democrat in a Montgomery State Senate seat, the 17th. All four statewide Democratic candidates carried Montgomery in 2008, with Barack Obama receiving 60% of the county's vote.

Montgomery County is governed by a three-person County Commission. The current composition is two Republicans and one Democrat. By law, the County Commission must have one member of a minority party represented.

The current commissioners are:

The county row officers are:

  • Clerk of Courts - Ann Thornburg Weiss (D)
  • Controller - Diane Morgan (D)
  • Coroner - Walter Hoffman (D)
  • District Attorney - Risa Vetri Ferman (R)

  • Recorder of Deeds - Nancy Becker (R)
  • Register of Wills - D. Bruce Hanes (D)
  • Sheriff - Eileen Whalon Behr (R)
  • Treasurer - Thomas Jay Ellis (R)

The new officials took office in January 2008.
