Hamilton County is part of the Indianapolis-Carmel-Anderson, IN Metropolitan Statistical Area. Since the beginning of the 21st century, Hamilton County has been the second most populous county in Central Indiana.
Hamilton County's roots are in agriculture. However, after World War II, Indianapolis grew north and towns in the southern part of the county developed as suburbs. Residential and commercial development have replaced many farm fields. The northern part of the county remains largely agricultural. Today, the county is one of the fastest-growing counties in the United States. According to 2007 estimates by the U.S. Census, the county's population increased from an estimated 182,740 in 2000 to 261,661 in 2007, making it the fastest-growing county in Indiana out of 92. Recently[when?], Hamilton County surpassed St. Joseph County in population, making it the state's fourth most populous. It is also the third densest in the state, after Marion and Lake Counties.
Geist and Morse reservoirs are two man-made lakes in Hamilton County that offer recreational opportunities such as boating, fishing, and waterfront living.
In June 2008, Hamilton County was named America's Best Place to Raise a Family by Forbes.com due to its strong economy, affordable living, top-ranked schools, and close proximity to Indianapolis. The city of Carmel in southwestern Hamilton County was designated CNN Money's top place to live in 2013 and in 2017, the city of Fishers was named best place to live.
The land containing Hamilton County was brought into the possession of the United States by the Treaty of St. Mary's in 1818. William Conner was the first white settler in the county. In the summer of 1822, after realizing there were enough settlers in the area, Conner and other settlers applied to the Indiana Legislature for a charter authorizing them to become a separate and independent county under Indiana law. The application was presented to the Legislature at the 1822-23 session and the act was passed and approved by the governor on January 8, 1823. The act took effect on the first Monday in April (April 7), 1823. The County Commissioners first met on May 5, 1823, at the house of William Conner. Conner's house would also serve as the County Circuit Court. The county was named after Alexander Hamilton, the first secretary of the treasury.

Hamilton County is part of Indiana's 5th congressional district; Indiana Senate districts 20, 21, 28, 29 and 30; and Indiana House of Representatives districts 29, 32, 35, 36, 38, 39, 86, 87 and 88.
Hamilton County has long been reckoned as a classic Republican suburban stronghold. It has voted for the Republican presidential candidate at every election since Charles Evans Hughes in 1916. In 1912, Democratic candidate Woodrow Wilson had carried the county with a 3.06% plurality over Republican opponent William Taft. For years, Republicans usually won the county handily even in Democratic landslides. For instance, the county rejected Franklin Roosevelt in all four of his bids for president, and Barry Goldwater easily carried the county in 1964 with 61 percent of the vote. Since Wilson carried the county in 1912, a Republican has only carried it by fewer than 10 percentage points twice–in 1932, when Roosevelt held incumbent Herbert Hoover to 53 percent of the vote, and 2020, when Joe Biden held incumbent Donald Trump to 52.4 percent of the vote.
Hamilton County's loyalty to the Republican Party is not limited to presidential elections. The county regularly rejects Democrats in gubernatorial and senatorial races, and is typically one of the Republicans' strongest counties at the state level. One of the few times in recent memory that Hamilton County has supported a Democrat for governor or Senate was in 1992, when Evan Bayh narrowly carried it with 50.48 percent of the vote in his successful gubernatorial reelection bid. However, Bayh lost Hamilton County in his three bids for Senate.
In 2016, despite his statewide dominance that year, Trump turned in the weakest showing for a Republican nominee in Hamilton County since Hoover, winning just 56% of the vote. Thus, Hamilton County voted less Republican than the rest of the state for the first time in almost 100 years. Hillary Clinton won 36.7 percent of the vote, only the third time since Harry Truman that a Democrat had won more than 35 percent of the county's vote. Eight years earlier, Barack Obama received 38.45% of the county vote during the 2008 election, the strongest result for a Democrat since Roosevelt in 1936. Joe Donnelly in his 2018 senate re-election loss also came within 10 percent of winning the county, winning 44.4% of the vote.
In 2020, Joe Biden won the largest percentage of the vote for a Democrat in the history of the county (45.6%) while Donald Trump won the second smallest percentage ever (52.4%) for a Republican. It was the first time since 1936 that a Democrat even managed 40 percent of the county's vote, and only the second time in 88 years that a Republican had won the county by fewer than 10 points. This was seen as evidence that the county was changing from a conservative stronghold to a conservative-tilting swing county similar to many other suburban areas. Biden carried both Carmel and Fishers.
According to the 2010 census, the county has a total area of 402.44 square miles (1,042.3 km2), of which 394.27 square miles (1,021.2 km2) (or 97.97%) is land and 8.17 square miles (21.2 km2) (or 2.03%) is water.
