With the issuance of a bond ordinance for a series of roads connecting nearby settlements, the establishment of the University of Louisiana System's Lafayette campus, and the continued diversification of its economy, Lafayette and its metropolitan area have experienced population growth since the 1840 census and was promptly nicknamed "The Hub City." The city and parish of Lafayette are also known as the "Heart of Acadiana."
