Map - Hartford City, Indiana (Hartford City)

Hartford City is a city in the U.S. state of Indiana, and the county seat of Blackford County. Located in the northeast central portion of the state, the small farming community underwent a dramatic 15-year economic boom beginning in the late 1880s. The Indiana Gas Boom resulted from the discovery and exploitation of natural gas in the area. The rural economy was transformed to one that included manufacturing. The boom attracted workers and residents, retail establishments, and craftspeople. The increased population was a catalyst for the construction of roads, schools, and churches. After the boom came a long period of growth and stability. Agriculture (and agricultural trade) remained as the basis for the economy.

From the 1920s through the 1970s, Hartford City continued to thrive. Agricultural automation and consolidation of small farms into industrial-size farms resulted in a decline in the population; the small farmer became unable to compete and fewer laborers were needed. Some workers turned to the manufacturing and construction sectors for employment in nearby cities. However, manufacturing hubs such as Muncie and Marion suffered the collapse of their economies during industrial restructuring when large factories closed. Despite the decline, Hartford City was able to retain the paper company, 3M.

The city government has concentrated on bringing manufacturing to Hartford City and has had some success in securing state funding for businesses that use recycled or agricultural materials in the manufacturing process. Younger people leave to attend college and pursue professional careers outside the scope of those available in Hartford City. Community college, private colleges, and a university are within commuting distance; however, Hartford City lacks rental housing appropriate to college students or young adults. The town's population was 6,220 at the 2010 United States Census.

Hartford City, Indiana began in the late 1830s as a few log cabins clustered near a creek. Folklore taught in local elementary schools suggests that Hartford City was originally known as “Hart's ford,” a place to cross Lick Creek. The name evolved to Hartford, and eventually to Hartford City. (This was to avoid confusion with another Hartford in the state.)

The community was designated as the county seat of Blackford County. During the last half of the 19th century, East Central Indiana consisted mostly of rural farming communities, including Hartford City. The town's population did not exceed 2,000 until after 1887, when the region began to grow because of the Indiana Gas Boom.

Hartford City's population tripled in the next decade, as manufacturers were lured to the region to take advantage of low costs for land and the natural gas. Hartford City benefited from railroad service from two railroads in addition to a natural gas supply that was thought to be unlimited. Manufacturers such as Hartford City Glass Company, Sneath Glass Company, Hartford City Paper, Utility Paper, and Willman Lumber all located or began in Hartford City during the 1890s. Although the supply of natural gas was soon exhausted, many of these businesses continued to operate into the 1950s and beyond. Hartford City leaders attracted businesses such as Overhead Door (1923) and 3M (1955) to replace the glass factories as major employers in the city.
