Hamilton County’s roots are in agriculture. However after World War II, Indianapolis grew north and the county and the towns within it developed as a suburb. Many farm fields have been replaced by both residential and commercial development.
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 is the fastest growing county in Indiana out of 92. Recently, Hamilton County surpassed St. Joseph County in population, making it the fourth most populous in the state.
Geist and Morse reservoirs are two man-made lakes in Hamilton County that offer residents and visitors 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.
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 has been won by every Republican presidential candidate since Charles Evans Hughes in 1916. In 1912, Democrat candidate Woodrow Wilson had carried the county with a 3.06% majority over its Republican opponent William Taft.
Although Barack Obama got only 38.45% of Hamilton County's vote during the 2008 election, it is the highest percentage a Democrat presidential candidate has been able to get for this county since Franklin D. Roosevelt in 1936 (who himself had also lost the county).
Hamilton County's loyalty for the Republican Party is not limited to presidential elections. The county regularly rejects Democrats in gubernatorial and senatorial races, usually by giving the Republican candidate some the state's highest percentage results. Even US senator Evan Bayh, in spite of his landslide victories in 1998 and 2004, had failed to carry Hamilton County in either election.
