Indianapolis, Indiana
"The fertile plains of the central agricultural zone form the second occupational region of Indiana. Indianapolis, a city designed after Versailles, France, and Washington, D.C., dominates the area; much of its growth has occurred through immigration from rural areas and annexation. A railway and highway hub, Indianapolis serves the surrounding farming belt as a distribution centre. It also is a major industrial city.
Evansville [Credit: Randella]The third region is one of mining, quarrying, and agriculture, and it spans much of the southern portion of the state. That area dominated Indiana’s early economy, which was dependent on the river traffic of the Ohio and Wabash. That dominance ended, however, with the advent of industry and railroads. The region’s major city, Evansville, continues to serve adjacent areas of Kentucky and Illinois, and between it and Terre Haute to the north lie most of the state’s oil and coal deposits. Southward from Bloomington is a vast limestone belt underlain by numerous caves, which makes the state a major limestone producer.
Hammond [Credit: John Delano]In the early 21st century more than three-fourths of the state’s residents lived in urban areas, and of these city dwellers more than one-third were concentrated in the Indianapolis metropolitan area alone. Another large segment of the population lived in the urban complex consisting of Gary, Hammond, and East Chicago. The national pattern of relocation from the central city to the suburbs has generally been evident throughout the state, with South Bend, for example, losing residents while the population of its surrounding county has grown.
Economy
For much of the 20th century, Indiana’s economy was dominated by manufacturing. The availability of labour and essential materials, the state’s location within 800 miles (1,280 km) of most of the country’s largest consumer and industrial markets, and the extensive interstate highway infrastructure all contributed to the growth of manufacturing in Indiana. Heavy industrialization, however, has made the state’s economy vulnerable to recession, and Indiana has had its share of labour strife, especially in the steel industry. By the early 21st century, manufacturing had begun to give way to services as the largest sector of the economy, and the biological sciences had become a principal focus of the state’s economic development efforts.
Agriculture
Along with forestry and fisheries, agriculture employs just a tiny segment of the labour force and generates a similarly small portion of the state’s gross product. Nevertheless, technological advances have meant that, despite drops in total farm acreage and number of farms, production has increased. The state is among the country’s top producers of corn (maize), soybeans, and mint. Tomatoes are the principal vegetable crop, but watermelons are important in the lower Wabash valley. The state also is one of the leading producers of hogs and dairy products. Other important livestock includes turkeys, ducks, and sheep.
Resources and power
Indiana is a major producer of building stone, quarried around Bedford and Bloomington in the southwest-central part of the state. Although bituminous coal from the southwest is a significant source of energy for the generation of electricity, supplies are able to meet only about half of the state’s demand. To fulfill the remaining need, coal is imported from other states. Natural gas, brought in by pipelines, emerged as an important secondary source of energy in the early 21st century, though during the 1880s Indiana’s “Gas Belt,” stretching from east-central Indiana south to the Ohio River, was the world’s largest producing field. Few attempts were made to conserve the gas, however, and by 1898 the supply was virtually exhausted.
Manufacturing
Manufacturing showed steady growth from the mid-19th to the late 20th century, during which time it emerged as a primary source of income for the state. By the early 21st century growth had slowed somewhat, but the sector still accounted for more than one-fourth of Indiana’s gross state product and employed a significant segment of the workforce. The steel and automotive industries, operating primarily out of the northwest, are the major components of the sector. The state also is a leading producer of pharmaceuticals, hardwood furniture, electrical products, caskets, and mobile homes. Elkhart, in the northeast, is well known for its production of musical (wind) instruments. Indianapolis, with a more diverse manufacturing base, is the state’s largest manufacturing city. Overall, Indiana ranks among the country’s top states in manufacturing."
