Alexandria is an independent city in the Commonwealth of Virginia in the United States. As of 2010, the population was 139,988, and in 2020, the population was estimated to be at 159,200. The city's estimated population has grown by 1% percent annually since 2010 on average. Located along the western bank of the Potomac River, Alexandria is approximately 7 miles (11 km) south of downtown Washington, D.C. Like the rest of Northern Virginia, as well as Central Maryland, modern Alexandria has been influenced by its proximity to the U.S. capital. It is largely populated by professionals working in the federal civil service, in the U.S. military, or for one of the many private companies which contract to provide services to the federal government. One of Alexandria's largest employers is the U.S. Department of Defense. Another is the Institute for Defense Analyses. In 2005, the United States Patent and Trademark Office moved to Alexandria, and in 2017, so did the headquarters of the National Science Foundation. The historic center of Alexandria is known as Old Town. With its concentration of boutiques, restaurants, antique shops and theaters, it is a major draw for all who live in Alexandria as well for visitors. Like Old Town, many Alexandria neighborhoods are compact and walkable. It is the 7th largest and highest-income independent city in Virginia. A large portion of adjacent Fairfax County, mostly south but also west of the city, has Alexandria mailing addresses. However, this area is under the jurisdiction of Fairfax County's government and separate from the independent city. The city is therefore sometimes referred to as the "City of Alexandria" to avoid confusion (see the "Neighborhoods" paragraph below). Additionally, neighboring Arlington County was formerly named "Alexandria County" before it was renamed by the Virginia General Assembly in 1920 to reduce confusion with the city.
National Harbor is situated on the banks of the historic Potomac River, just minutes from the nation’s capital. Featuring 350 acres of waterfront resort space, National Harbor is a destination unlike any other.
