Austin is the capital city of the U.S. state of Texas, as well as the seat and largest city of Travis County, with portions extending into Hays and Williamson counties. Incorporated on December 27, 1839, it is the 11th-most-populous city in the United States, the fourth-most-populous city in Texas, the second-most-populous state capital city, and the most populous state capital that is not also the most populous city in its state. It has been one of the fastest growing large cities in the United States since 2010. Downtown Austin and Downtown San Antonio are approximately 80 miles (129 km) apart, and both fall along the Interstate 35 corridor. Some observers believe that the two regions may some day form a new "metroplex" similar to Dallas and Fort Worth. Austin is the southernmost state capital in the contiguous United States and is considered a Beta−level global city as categorized by the Globalization and World Cities Research Network.
As of 2021, Austin had an estimated population of 964,177, up from 961,855 at the 2020 census. The city is the cultural and economic center of the Austin–Round Rock metropolitan statistical area, which had an estimated population of 2,295,303 as of July 1, 2020, a roughly 84% increase from the year 2000. Located in Central Texas within the greater Texas Hill Country, it is home to numerous lakes, rivers, and waterways, including Lady Bird Lake and Lake Travis on the Colorado River, Barton Springs, McKinney Falls, and Lake Walter E. Long.
Austin, Travis County and Williamson County have been inhabited since at least 9200 BC. The earliest known inhabitants lived during the late Pleistocene (Ice Age) and are linked to the Clovis culture. Spanish colonists, including the Espinosa-Olivares-Aguirre expedition, traveled through the area, but few permanent settlements were created. In 1730, three Catholic missions were combined and reestablished as one mission on the south side of the Colorado River. In the 1830s, pioneers began to settle the area in central Austin along the Colorado River, but growth was stagnant due to conflicts with the regional Native Americans.
In 1835-1836, Texans fought and won independence from Mexico, becoming an independent country with its own president, congress, and monetary system. The Texas Congress formed a commission to seek a site for a new capital of the Republic of Texas to replace Houston. Mirabeau B. Lamar recommended the area on the north bank of the Colorado River, which was seen as a convenient crossroads for trade routes between Santa Fe and Galveston Bay. Edwin Waller was chosen to survey the village and draft a plan laying out the new capital. The original site was narrowed to 640 acres (260 ha) that fronted the Colorado River between two creeks, Shoal Creek and Waller Creek, which was later named in his honor.
Waller and a team of surveyors developed Austin's first city plan, known as the Waller Plan, dividing the site into a 14-block grid plan bisected by a broad north–south thoroughfare, Congress Avenue, running up from the river to Capital Square. In 1840, a series of conflicts between the Texas Rangers and the Comanches led to the Council House Fight and the Battle of Austin.
Austin, the southernmost state capital of the contiguous 48 states, is located in Central Texas on the Colorado River. Austin is 146 miles (230 km) northwest of Houston,[58] 182 miles (290 km) south of Dallas and 74 miles (120 km) northeast of San Antonio.
Austin occupies a total area of 305.1 square miles (790.1 km2). Approximately 7.2 square miles (18.6 km2) of this area is water. Austin is situated at the foot of the Balcones Escarpment, on the Colorado River, with three artificial lakes within the city limits: Lady Bird Lake (formerly known as Town Lake), Lake Austin (both created by dams along the Colorado River), and Lake Walter E. Long that is partly used for cooling water for the Decker Power Plant. Mansfield Dam and the foot of Lake Travis are located within the city's limits. Lady Bird Lake, Lake Austin, and Lake Travis are each on the Colorado River.
The elevation of Austin varies from 425 feet (130 m) to approximately 1,000 feet (305 m) above sea level. Due to the fact it straddles the Balcones Fault, much of the eastern part of the city is flat, with heavy clay and loam soils, whereas the western part and western suburbs consist of rolling hills on the edge of the Texas Hill Country. Because the hills to the west are primarily limestone rock with a thin covering of topsoil, portions of the city are frequently subjected to flash floods from the runoff caused by thunderstorms. To help control this runoff and to generate hydroelectric power, the Lower Colorado River Authority operates a series of dams that form the Texas Highland Lakes. The lakes also provide venues for boating, swimming, and other forms of recreation within several parks on the lake shores.
Austin is located at the intersection of four major ecological regions, and is consequently a temperate-to-hot green oasis with a highly variable climate having some characteristics of the desert, the tropics, and a wetter climate. The area is very diverse ecologically and biologically, and is home to a variety of animals and plants. Notably, the area is home to many types of wildflowers that blossom throughout the year but especially in the spring. This includes the popular bluebonnets, some planted by "Lady Bird" Johnson, wife of former President Lyndon B. Johnson.
Austin's skyline historically was modest, dominated by the Texas State Capitol and the University of Texas Main Building. However, since the 2000s, many new high-rise towers have been constructed. Austin is currently undergoing a skyscraper boom, which includes recent construction on new office, hotel and residential buildings. Downtown's buildings are somewhat spread out, partly due to a set of zoning restrictions that preserve the view of the Texas State Capitol from various locations around Austin, known as the Capitol View Corridors.
At night, parts of Austin are lit by "artificial moonlight" from moonlight towers built to illuminate the central part of the city. The 165-foot (50 m) moonlight towers were built in the late 19th century and are now recognized as historic landmarks. Only 15 of the 31 original innovative towers remain standing in Austin, but none remain in any of the other cities where they were installed. The towers are featured in the 1993 film Dazed and Confused.
The central business district of Austin is home to the tallest condo towers in the state, with The Independent (58 stories and 690 ft (210 m) tall) and The Austonian (topping out at 56 floors and 685 ft (209 m) tall). The Independent became the tallest all-residential building in the U.S. west of Chicago when topped out in 2018. In 2005, then-Mayor Will Wynn set out a goal of having 25,000 people living downtown by 2015. Although downtown's growth did not meet this goal, downtown's residential population did surge from an estimated 5,000 in 2005 to 12,000 in 2015. The skyline has drastically changed in recent years, and the residential real estate market has remained relatively strong. As of December 2016, there were 31 high rise projects either under construction, approved or planned to be completed in Austin's downtown core between 2017 and 2020. Sixteen of those were set to rise above 400 ft (120 m) tall, including four above 600', and eight above 500'. An additional 15 towers were slated to stand between 300' and 399' tall.
Austin is located within the middle of a unique, narrow transitional zone between the dry deserts of the American Southwest and the lush, green, more humid regions of the American Southeast. Its climate, topography, and vegetation share characteristics of both. Officially, Austin has a humid subtropical climate under the Köppen climate classification. This climate is typified by long, very hot summers, short, mild winters, and warm to hot spring and fall seasons in-between. Austin averages 34.32 inches (872 mm) of annual rainfall distributed mostly evenly throughout the year, though spring and fall are the wettest seasons. Sunshine is common during all seasons, with 2,650 hours, or 60.3% of the possible total, of bright sunshine per year.
Typical of Central Texas, severe weather in Austin is a threat that can strike during any season. However, it is most common during the spring. According to most classifications, Austin lies within the extreme southern periphery of Tornado Alley, although many sources place Austin outside of Tornado Alley altogether. Consequently, tornadoes strike Austin less frequently than areas farther to the north. However, severe weather and/or supercell thunderstorms can occur multiple times per year, bringing damaging winds, lightning, heavy rain, and occasional flash flooding to the city.
In 2020, there were 961,855 people, up from the 2000 United States census tabulation where there were 656,562 people, 265,649 households, and 141,590 families residing in the city. In 2000, the population density was 2,610 inhabitants per square mile (1,010/km2). There were 276,842 dwelling units at an average density of 1,101 per square mile (425/km2).

The median house price was $185,906 in 2009, and it has increased every year since 2004.[needs update][108] The median value of a house which the owner occupies was $318,400 in 2019—higher than the average American home value of $240,500.
The Greater Austin metropolitan statistical area had a gross domestic product (GDP) of $86 billion in 2010. Austin is considered to be a major center for high tech. Thousands of graduates each year from the engineering and computer science programs at the University of Texas at Austin provide a steady source of employees that help to fuel Austin's technology and defense industry sectors. The region's rapid growth has led Forbes to rank the Austin metropolitan area number one among all big cities for jobs for 2012 in their annual survey and WSJ Marketwatch to rank the area number one for growing businesses. As a result of the high concentration of high-tech companies in the region, Austin was strongly affected by the dot-com boom in the late 1990s and subsequent bust. Austin's largest employers include the Austin Independent School District, the City of Austin, Dell, the U.S. Federal Government, NXP Semiconductors, IBM, St. David's Healthcare Partnership, Seton Family of Hospitals, the State of Texas, the Texas State University, and the University of Texas at Austin.
Other high-tech companies with operations in Austin include 3M, Apple, Amazon, AMD, Apartment Ratings, Applied Materials, Arm Holdings, Bigcommerce, BioWare, Blizzard Entertainment, Buffalo Technology, Cirrus Logic, Cisco Systems, Dropbox, eBay, Electronic Arts, Flextronics, Facebook, Google, Hewlett-Packard, Hoover's, HomeAway, HostGator, Intel Corporation, National Instruments, Nintendo, Nvidia, Oracle, PayPal, Polycom, Qualcomm, Rackspace, RetailMeNot, Rooster Teeth, Samsung Group, Silicon Labs, Spansion, Tesla, United Devices, VMware, Xerox, and Zoho Corporation. In 2010, Facebook accepted a grant to build a downtown office that could bring as many as 200 jobs to the city. The proliferation of technology companies has led to the region's nickname, "Silicon Hills", and spurred development that greatly expanded the city.
Austin is also emerging as a hub for pharmaceutical and biotechnology companies; the city is home to about 85 of them. In 2004, the city was ranked by the Milken Institute as the No. 12 biotech and life science center in the United States and in 2018, CBRE Group ranked Austin as #3 emerging life sciences cluster.[136] Companies such as Hospira, Pharmaceutical Product Development, and ArthroCare Corporation are located there.
Whole Foods Market, an international grocery store chain specializing in fresh and packaged food products, was founded and is headquartered in Austin.
Other companies based in Austin include NXP Semiconductors, GoodPop, Temple-Inland, Sweet Leaf Tea Company, Keller Williams Realty, National Western Life, GSD&M, Dimensional Fund Advisors, Golfsmith, Forestar Group, EZCorp, Outdoor Voices, Tito's Vodka, Indeed, Speak Social, and YETI.
In 2018, Austin metro-area companies saw a total of $1.33 billion invested. Austin's VC numbers were so strong in 2018 that they accounted for more than 60 percent of Texas' total investments.
