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 experienced a 15-year economic boom beginning in the late 1880s – the Indiana Gas Boom, caused by the discovery of natural gas in the area, which transformed the area from an agricultural economy to one that also included manufacturing. The boom brought residents, retail establishments, and craftspeople. The increased population meant construction of roads, schools, and churches. After the boom came a long period of growth and stability. Agriculture (and agricultural trade) remained as the fundamental industry.
From the 1920s through the 1970s, Hartford City continued to thrive. Agricultural automation and consolidation of small farms into industrial-size farms started a decline in the population as 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 like Muncie and Marion saw the collapse of their economies when large factories closed. Despite the decline, Hartford City was able to retain its paper company, 3M. The city government has concentrated on bringing manufacturing to Hartford City and has had some success on securing state funding for businesses that use recycled materials or agricultural materials in the manufacturing process.
