The post-World War II housing boom and new jobs brought growth to the city. The population increased from 2,400 in 1940 to 22,000 in 2000. The city has expanded to the north by annexing several sizable suburbs. By 1981 the State of Indiana changed statutes to convert the managing board of trustees to a council with members rather than trustees. In 1990 voters approved expansion of members of the Town Council from five to seven following the area growth. Clarksville is now the major shopping hub of Southern Indiana, with the hub area centered on Lewis and Clark Parkway and nearby Veterans Parkway.
