Indianapolis is the capital of the U.S. state of Indiana. According to the 2000 Census, its population is 791,926, making it Indiana's most populous city and the 12th largest city in the U.S. The U.S. Census July 1, 2004 estimate for the Consolidated City of Indianapolis is 794,160 and the combined Metro Area (an agglomeration called the Nine-County Region) has a population approaching 2 million residents. Indianapolis is the third largest city in the midwest after Chicago and Detroit and is one of only three major cities in the midwest which had a growth rate above 5%. At the current rate, Indianapolis will be the second largest city in the midwest by 2010. Indianapolis is the county seat of Marion County. As of 2004, Marion County's population is 863,596.
According to the United States Census Bureau, "the balance" (that part of Marion County not part of another municipality) has a total area of 953.5 km2 (368.2 mi2). 936.2 km2 (361.5 mi2) of it is land and 17.3 km2 (6.7 mi2) of it is water. The total area is 1.81% water. These figures are slightly misleading because they do not represent the entire Consolidated City of Indianapolis (all of Marion County, except the four "excluded" communities). The total area of the Consolidated City of Indianapolis, which does not count the four "excluded" communities, covers approximately 966.3 km2 (373.1 mi2).
At the center of Indianapolis is the One-Mile Square, bounded by East, West, North, and South Streets. Four diagonal streets pass through the corners of the Square but stop one to five blocks (depending on the street) before reaching the Circle. Nearly all of the streets in the One-Mile Square are named after U.S. states. (The exceptions are Meridian Street, which numerically divides west from east; Market Street, which intersects Meridian Street at Monument Circle; and Capitol and Senate Avenues, where many of the Indiana state government buildings are located. The street-numbering system centers not on the Circle, but rather one block to the south, where Meridian Street intersects Washington Street -- National Road.).
Indianapolis experiences a continental climate typical of cities at this latitude which lie far from any significant body of water. It experiences hot summers, with high reaching into the 90s at times and lows in the 60s. Humidity varies, depending on the position of weather fronts and prevailing winds. Winters are rather long and cold, with significant snowstorms blowing in from the Great Lakes region. Wind chills can reach into the negative 20s, with no natural features like mountains to protect the area from the onslaught of arctic Canadian air. Spring and fall bring pleasant temperatures and the occurrence of many thunderstorms which, due to the lack of hills or mountains, often bring tornadoes.
The average July high is 86°F (30°C), with the low being 61°F (16°C). January highs average 34°F (1°C), and lows 18°F (-8°C). The record high for Indianapolis is 104.0°F (40°C), on July 14th, 1954. The record low is -27°F (-33°C), on January 19th, 1994. Snowfall varies from about 20 to 30 inches a year.

Indianapolis was founded as the state capital in 1821 by an act of the Indiana General Assembly. Prior to its official founding, Indianapolis was a sparsely settled swampy area. The first European American settler is generally believed to be George Pogue, who on March 2, 1819 settled in a double log cabin along the White River in what is now White River State Park in downtown Indianapolis. The state commissioned Alexander Ralston to design the new capital city. Ralston was an apprentice to the French architect Pierre L'Enfant, and he helped L'Enfant plan Washington, DC. Ralston's original plan for Indianapolis called for a city of only 1 square mile. Under Ralston's plan, at the center of the city was placed the Governor's Circle, a large circular commons, which was to be the site of the Governor's mansion. It was used as a market commons for over six years. Although an expensive Governor's mansion was finally constructed in 1827, no Governor ever lived in the house at Governor's Circle, as the site in the city center lacked any privacy. The Governor's mansion was finally demolished in 1857. (See History of Indianapolis and Marion County Indiana by B.R. Sulgrove, 1884). Later, Governor's Circle became Monument Circle after the impressive 284-feet tall neoclassical limestone and bronze State Soldiers' and Sailors' Monument, designed by German architect Bruno Schmitz, was completed on the site in 1901.
