on February 13, 1905. Arkansas is known for extreme weather and frequent storms. A typical year brings thunderstorms, tornadoes, hail, snow and ice storms. Between both the Great Plains and the Gulf States, Arkansas, receives around 60 days of thunderstorms. Arkansas is located in Tornado Alley, and as a result, a few of the most destructive tornadoes in U.S. history have struck the state. While sufficiently far from the coast to avoid a direct hit from a hurricane, Arkansas can often get the remnants of a tropical system, which dumps tremendous amounts of rain in a short time and often spawns smaller tornadoes. Cities and towns Little Rock has been Arkansas's capital city since 1821 when it replaced Arkansas Post as the capital of the Territory of Arkansas. The state capitol was moved to Hot Springs and later Washington during the American Civil War when the Union armies threatened the city in 1862, and state government did not return to Little Rock until after the war ended. Today, the Little Rock–North Little Rock–Conway metropolitan area is the largest in the state, with a population of 724,385 in 2013. The Fayetteville–Springdale–Rogers Metropolitan Area is the second-largest metropolitan area in Arkansas, growing at the fastest rate due to the influx of businesses and the growth of the University of Arkansas and Walmart. The state has eight cities with populations above 50,000 (based on 2010 census). In descending order of size, they are Little Rock, Fort Smith, Fayetteville, Springdale, Jonesboro, North Little Rock, Conway, and Rogers. Of these, only Fort Smith and Jonesboro are outside the two largest metropolitan areas. Other cities in Arkansas include Pine Bluff, Crossett, Bryant, Lake Village, Hot Springs, Bentonville, Texarkana, Sherwood, Jacksonville, Russellville, Bella Vista, West Memphis, Paragould, Cabot, Searcy, Van Buren, El Dorado, Blytheville, Harrison, Dumas, Rison, Warren, and Mountain Home. Demographics Population The United States Census Bureau estimated that the population of Arkansas was 3,017,804 on July 1, 2019, a 3.49% increase since the 2010 United States census. At the 2020 U.S. census, Arkansas had a resident population of 3,011,524. From fewer than 15,000 in 1820, Arkansas's population grew to 52,240 during a special census in 1835, far exceeding the 40,000 required to apply for statehood. Following statehood in 1836, the population doubled each decade until the 1870 census conducted following the American Civil War. The state recorded growth in each successive decade, although it gradually
