Saratoga County lies in the heart of eastern New York State's recognized Tech Valley, a growing center for the computer hardware side of the high-technology industry and its concomitant venture capital investment, with great strides in the nanotechnology sector, digital electronics design, and water- and electricity-dependent integrated microchip circuit manufacturing, and more recently, artificial intelligence, involving companies including IBM, GlobalFoundries, Samsung, and Taiwan Semiconductor, among others.

[8][9][10] In April 2021, GlobalFoundries, a company specializing in the semiconductor industry, moved its headquarters from Silicon Valley, California to its most advanced semiconductor-chip manufacturing facility in Saratoga County near a section of the Adirondack Northway, in Malta, New York.

This was an enormous county, including the northern part of New York, as well as all of the present state of Vermont and, in theory, extending westward to the Pacific Ocean.

The Battles of Saratoga (September 19 and October 7, 1777) marked the climax of the Saratoga campaign, giving a decisive victory to the Americans over the British in the American Revolutionary War, which convinced France that the Thirteen Colonies could win the war.

The government of Louis XVI began lending military and financial aid to the American Patriot cause.

The highway, designated Interstate 87, is the primary conduit connecting the capital of New York, Albany, northward across the Thaddeus Kosciusko Bridge into and through Saratoga County, then past Lake George in the Adirondack Park, through the Adirondack Mountains, and eventually to the Canada–United States border, where it continues seamlessly as Quebec Autoroute 15 to Montreal.

[24] Originated in 1998 to promote the greater Albany area as a high-tech competitor to regions such as Silicon Valley and Boston, it has since grown to represent the counties in the Capital District and extending to IBM's Westchester County plants in the south and the Canada–US border to the north.

[10] Tech Valley encompasses 19 counties straddling both sides of the Adirondack Northway and the New York Thruway,[24] and with heavy state taxpayer subsidy, has experienced significant growth in the computer hardware side of the high-technology industry, with great strides in the nanotechnology sector, digital electronics design, and water- and electricity-dependent integrated microchip circuit manufacturing, and more recently, artificial intelligence,[8] involving companies including GlobalFoundries in Malta and others.

Adirondack Trust Company is the largest independent community bank in Saratoga County.

Adirondack Trust's 167 full-time employees own the company, which offers banking, loans and investment services, along with insurance through its Amsure subsidiary.

[28] The Saratoga National Historical Park is located along the Hudson River in Stillwater, and features a drive-around trail where one can drive up to each station.

The park is also famous for its outstanding views of the area's natural scenery and Vermont's Green Mountains in the distance.

[29] A portion of northwestern Saratoga County lies within the boundaries of the Adirondack Park and includes Hadley Mountain.

By long-standing tradition, whoever serves as chairman of the Board of Supervisor's powerful Law and Finance Committee one year serves as chairman of the full Board the following year—a tradition that has been broken only three times in Saratoga County's history.

In 2016, Saratoga County flipped back to the Republicans, with Donald Trump capturing a narrow plurality of the vote over Hillary Clinton.

In the State Senate, the county is divided between Republicans Daphne Jordan and Jim Tedisco, while in the State Assembly Democrats John T. McDonald III and Carrie Woerner, along with Republicans Mary Beth Walsh and Dan Stec, each represent portions of the county.

In 2005, the Democrats gained a majority on the Saratoga Springs City Council after decades of Republican dominance.

The Republicans, however, reclaimed the council majority in the 2007 General Elections due to a split Democratic Party in the mayor's race.

In 2011, Democrats reclaimed the Majority on the City Council, while Republican Scott Johnson was reelected as Mayor.
