Population (2010 Estimate) 1,344,436

Nassau County MapNassau County is one of four counties on Long Island, though two of those counties make up the New York City boroughs of Brooklyn and Queens. Along with the far larger Suffolk County to its east, Nassau County is one of the two counties that make up what people traditionally call “Long Island.” It is among the richest counties in the United States, and has a total population larger than many cities in the country. Its coastal location and overall affluence make it a popular vacation destination, as well as a proper relocation destination for New York professionals and retirees.

Nassau’s northwest corner has become known as the Gold Coast, for its impressive expanse of mansions. Former American President Theodore Roosevelt, who owned a house on Sagamore Hill at Oyster Bay, said of Nassau County, “There could be no healthier place to bring children up.” he wrote. This truth is affirmed even today by the 1.3 million people who have made Nassau County their home.

Originally, Long Island only consisted of three counties: Kings, Queens, and Suffolk. These communities, which were mostly agricultural, experienced changes after being colonized. In 1898, when Queens County was included in greater New York, the eastern townspeople from Hempstead, North Hempstead, and Oyster Bay proposed to form their own county: Nassau. The name reflects the county’s Dutch and English colonial past. Nassau officially became Long Island’s new county in January 1899.

World War II ignited a rich aviation industry in Long Island, and particularly in Nassau, where America’s most famous warplanes were manufactured. Nassau was the home of the Roosevelt Airfield, which was located in Garden City. What makes it significant? The Roosevelt Airfield was where the historic 1927 nonstop flight of Charles Lindbergh took off, going to Paris, France. However, the Roosevelt Airfield closed in 1951, resulting in commercial development, which included a shopping mall now known as the popular Roosevelt Field Mall. The mall is easily the largest and most highly trafficked mall in the county Outlet stores surround the Roosevelt Field Mall for added value, and are popular for people throughout the New York metropolitan area.

Garden City Country Club  Garden City Country Club, founded in 1899, is home to an 18-hole golf course.

For decades, Long Island has also been home to leading scientific researches and engineering. Sperry Gyroscope and other companies were concentrated mostly in Nassau County, in the Bethpage area. The company’s high technology devices such as gyrocompasses–analog computer-controlled bombsights, became in huge demand during WW-II. Later, in the 1950‘s during the Cold War, parts of Sperry Gyroscope were moved to Phoenix, Arizona. However, Nassau’s Sperry Gyroscope branch continues to excel in aviation electronics. That’s been due to the company’s research and development on avionics systems for NASA.

From the 1980s to the 1990s, Nassau County surged on, with various business and recreational infrastructures. A strong educational system backed these locations. Additionally, retail and service employment made Nassau an economically busy county. Offices opened at lighting-speeds, and Nassau provided an attractive home for white-collar jobs. Presently, Nassau County’s total income ranks in the top ten percent of the entire United States.

Nassau County is indisputably part of the New York metropolitan area, with a western border that touches on both Queens and Brooklyn. For this reason, the county is served chiefly by the Metropolitan Transit Authority that operates the New York subways and other urban routes. Residents of Nassau are chiefly dependent on the Long Island Rail Road for transportation westward into the city, or eastward into Suffolk County and the Hamptons. Bus routes also serve the area.

Nassau County itself is located just across Long Island Sound from Connecticut on its northern border, while its southern edge borders the Atlantic Ocean. To the west is New York City, and to the east is the expansive Suffolk County that contains some of the most premiere vacation destinations for the wealthiest residents of the country. Nassau County’s proximity to both Connecticut and New York make it a popular “bedroom community” for professionals who work in the city but prefer to leave the Manhattan hustle and bustle behind after a long day of work.

Nassau County was largely a Republican stronghold for the 100 years leading up to the 1990s. During the 90s, political affiliation in the county began to shift leftward to the Democratic Party, with Bill Clinton winning the county both times during his time in office. Al Gore, John Kerry, and Barack Obama have all carried Nassau County since then, with no Republican winning the county in the race for President.
