Northwest Arkansas

Northwest Arkansas (NWA) is a metropolitan area and region in Arkansas within the Ozarks. It includes four of the ten largest cities in the state: Fayetteville, Springdale, Rogers, and Bentonville, the surrounding towns of Benton and Washington counties, and adjacent rural Madison County, Arkansas. The United States Census Bureau-defined Fayetteville–Springdale–Rogers Metropolitan Statistical Area includes 3,213.01 square miles (8,321.7 km²) and 590,337 residents (as of 2023), ranking NWA as the 98th most-populous metropolitan statistical area in the U.S. and the 13th fastest growing in the United States.

Northwest Arkansas doubled in population between 1990 and 2010. Growth has been driven by the three Fortune 500 companies based in NWA: Walmart, Tyson Foods, and J.B. Hunt Transport Services, Inc., the University of Arkansas, as well as nearly 1,300 suppliers and vendors drawn to the region by the large businesses. There are also several large private employers like Simmons Foods in Siloam Springs. The region has also seen significant investment in amenities, including the Crystal Bridges Museum of American Art, the Walton Arts Center, the Walmart AMP, TheatreSquared, and the NWA Razorback Regional Greenway.

"We’re like five siblings, if you will, fighting for crumbs that fall off the table instead of joining together with a common voice and say the same thing that this is the No. 1 highway project in Northwest Arkansas."

The region is also sometimes known as "the 479" after the telephone area code that serves the region, though the Fort Smith metro also uses the 479 area code. Occasionally, the Fort Smith metro is included in "Northwest Arkansas", though it is within the geographically distinct Arkansas River Valley region and separated from the subject region by the sparsely populated Boston Mountains.

Northwest Arkansas is located in the Southern United States. It is within the Upper South, characterized by the Ozarks. The southern part of NWA is a high and deeply dissected plateau, full of sparsely populated oak-hickory forest, separating the region from the Arkansas River Valley to the south.

Settlements were initially founded in the 19th century and early 20th century as individual communities, with Fayetteville, Springdale, Rogers, and Bentonville serving as historic population centers in the area. Growth began during the mid-20th century, a period of suburbanization largely rooted in automobile dependency. Thus the Northwest Arkansas cities expanded toward one another along major transportation corridors, in some cases becoming seamlessly connected urban areas such as Prairie Grove and Farmington along US 62 now connected to Fayetteville's southwest side. The transition from individual communities separated by rural or agricultural lands accelerated rapidly in the 1990s and early 2000s, as the population of the region doubled. Cities began rapidly annexing unincorporated lands, especially near the four-largest focal cities, adding an additional 45.5 square miles (118 km²) or 16% of incorporated size between 2000 and 2004. The Northwest Arkansas Regional Planning Commission (NWARPC, the region's metropolitan planning organization) expanded its planning area to include all of Benton and Washington counties in 2003. Annexations along transportation corridors spurred the need for expanding roadways, including along US 62 southwest of Fayetteville and northeast of Rogers, and Highway 59 north from Siloam Springs.

The United States Census Bureau definition includes Benton, Washington, and Madison counties in Arkansas. Until 2018, the Census Bureau also included McDonald County, Missouri.

Fayetteville is the county seat of Washington County, home to the University of Arkansas, and the principal city of Northwest Arkansas. As of the 2020 census, the city had a total population of 93,949. The city is the second most populous in Arkansas and serves as the county seat of Washington County. It's also known for Dickson Street, perhaps the most prominent entertainment district in the state of Arkansas, which itself contains the Walton Arts Center. Blocks from Dickson Street is the Fayetteville Historic Square, which hosts the nation's number one ranked Fayetteville's Farmer's Market. Fayetteville was also ranked 8th on Forbes Magazine's Top 10 Best Places in America for Business and Careers in 2007. Business Insider named Fayetteville the 2nd best place to live in the South in 2016.
