Economy of Chicago
News •
Besides church steeples and skyscrapers, smokestacks have long dominated the Chicago horizon. The city’s position as a rail hub and a port aided its use of the Midwest’s raw materials to produce a wide range of goods: light manufactures such as food, food products, candy, pharmaceuticals, and soap; communication equipment, scientific instruments, and automobiles; and refined petroleum, petroleum products, and steel. The city also became a major printing and publishing center. This diversity originally grew out of Chicago’s role as a transshipment point for eastbound grain and lumber as well as meat, which was smoked or packed in salt. The city assumed a new role as manufacturer of military supplies during the American Civil War, adding leather goods, steel rail, and food processing. Although railroading, steel, and meatpacking continued to be the largest employers, by the late 19th century manufacturing was branching into chemicals, furniture, paint, metalworking, machine tools, railroad equipment, bicycles, printing, mail-order sales, and other fields that were considered the cutting edge in their day. The production of most of the country’s telephone equipment made Chicago the Silicon Valley of an earlier era. Industrial diversification also depended on a skilled workforce, whose numbers were enhanced through a tradition of innovative vocational training.
Manufacturing
Although Chicago failed to attract the automobile-manufacturing dominance it sought, its other industries thrived through much of the 20th century. It became a major radio and electronics center during the 1920s. Like all manufacturing cities, Chicago was devastated by the Great Depression. The World War II boom involved more than 1,400 companies producing a wide range of military goods. Diversification, however, also made Chicago’s job market vulnerable to changes in almost any industry. In addition, the city’s abundant multistory factory buildings, which were often located in congested districts, could not compete with newer suburban industrial parks that had their sprawling single-story plants and access to expressways. Many companies sought new (and cheaper) labor markets south and west in the Sun Belt or overseas while keeping their headquarters in Chicago. Estimates of industrial jobs lost during the first four postwar decades run as high as one million, but manufacturing has remained a significant—if diminished—component of the regional economy.
Finance and other services
The drop in manufacturing’s preeminence has been mirrored by a dramatic rise in the service sector, which now employs some one-third of the city’s workforce. Notably, Chicago has fallen back on its original preindustrial role as a trading center. The city’s rapid early growth and its location as the rail hub amid the country’s farm belt made it the logical site for commodities trading. In 1848, traders created the Chicago Board of Trade to rationalize the process of purchasing and forwarding grain to Eastern markets. Over the years the scope of its trading expanded to include a number of commodities, and in 1973 it spun off an independent Chicago Board Options Exchange to regularize trading of corporate stock options. Meanwhile, in 1874 the new Chicago Produce Exchange began providing trading services for butter, eggs, poultry, and other farm product markets; in 1919 it changed its name to the Chicago Mercantile Exchange. The fourth trading institution, the Chicago Stock Exchange, was organized in 1882 to handle corporate securities; mergers with exchanges in other cities led to it being renamed the Midwest Stock Exchange in 1949, but the original name was restored in 1993. All four of these institutions—along with trading, banking, and other financial functions—have made the downtown LaSalle Street district synonymous with Chicago’s regional dominance, though the long-standing tradition of face-to-face trading that built them has experienced increased competition from electronic trading. Indeed, by the second decade of the 21st century, in-person deals in “the pits” represented just 1 percent of trading volume. The COVID-19 pandemic spelled the end of virtually all in-person trading, and, by 2022, just one trading pit remained open in Chicago’s exchanges.
Chicago, with dozens of major banks, remains second only to New York City as a national financial hub. However, local wholesaling and retailing have fallen increasingly under the control of out-of-town interests, which have either bought out or squeezed out department stores and retailers in several product lines.
Chicago’s position as a national transportation hub has long guaranteed the city a steady stream of conventions and trade shows. It has hosted numerous national political conventions since the one in 1860 that nominated Abraham Lincoln for the presidency. Older venues such as the Coliseum, the International Amphitheater, and the Chicago Stadium have given way to the United Center and the UIC Pavilion in the city and the Allstate Arena in suburban Rosemont, near O’Hare. McCormick Place, the lakefront convention complex just south of downtown, has been expanded several times to remain among the largest trade-show facilities in the country. Each year, McCormick Place alone hosts dozens of conventions and trade shows that draw many hundreds of thousands of people and pump considerable revenue into the local economy. Millions more businesspeople, tourists, and other short-term visitors come to the city annually to shop, dine, visit museums, and take in sporting and musical events, many of them staying in the region’s tens of thousands of hotel rooms.
Transportation
Chicago continues to be the country’s rail transportation hub. Each day thousands of Amtrak passengers arrive or change trains at Union Station, much as railway travelers did 150 years ago. The shift of freight carriers to containers has meant that rail yards and tracks are more likely to be filled with tractor trailers and stacks of giant boxes than boxcars and gondolas. Belt railways that circle the region still provide interchange between lines, but, as rail lines have consolidated, the corporate headquarters for much of the rail industry have left the city. Despite the preeminence of the railroads in handling freight, maritime industries survived and expanded to remain competitive in high bulk–low value hauling.
From the early days of commercial aviation, Chicago’s city government has recognized and capitalized on the advantageous flexibility of air routes over more-or-less permanent railroad tracks. During the 1920s the city established Municipal Airport on the Southwest Side, which quickly developed into one of the country’s busiest air hubs. However, by the end of the 1950s, the advent of jet airliners and their requirement of longer runways threatened to make landlocked Municipal obsolete. After long debate, the city chose to build a new facility by utilizing the old Orchard Field (hence the official acronym “ORD” used on luggage tags) in northwest suburban Park Ridge. In 1949 the new airport was named in honor of Lieut. Comdr. Edward (“Butch”) O’Hare, a wartime naval air hero, while Municipal was renamed Midway for the critical 1942 Allied naval victory in the Pacific. Long the undisputed busiest airport in the country, O’Hare more recently has competed with other large facilities across the country for the distinction, while a rejuvenated Midway became a regional hub. For decades the city has debated the issue of constructing a third major airport.
The move toward publicly operated mass transit grew out of adversity, as the Great Depression forced a collection of private streetcar and elevated-rail companies into bankruptcy. Public funding allowed the construction of a long-delayed subway system. Work began in 1938 on a north-south line under State Street that was completed in 1943, and a second, parallel route under Dearborn Street opened in 1950. These lines and the Loop elevated (“L”) structure—completed in 1897 and still the essential downtown link in the system—constitute the core of a network of rapid-transit rail lines that came to include service to O’Hare and Midway. Meanwhile, in 1945 the Illinois state legislature, the General Assembly, created the Chicago Transit Authority (CTA) to take over operation of the “L” carriers; independent bus companies were absorbed in 1952.
Although Chicago grew most rapidly while it rode “L” trains and streetcars, it also fell in love with the automobile. Chicago’s expressway system dates to the 1920s, when Lake Shore Drive was rebuilt as a divided highway. (Some claim it to be one of the country’s oldest expressways.) But the postwar rush to suburbia, automobile commuting, and the 1956 Interstate Highway Act brought about the construction of the modern network. The Congress Street (later Eisenhower) Expressway to the west, completed in 1956, was the region’s first interstate highway. During the following decade, a spiderweb of Loop-directed expressways and encircling bypass routes was superimposed on the region, which roughly followed the outlines of the original wagon-wheel pattern of settlement.
The move to the automobile left public transit in crisis. In 1973 the Illinois General Assembly created the Regional Transportation Authority (RTA) and gave it the power to levy a sales tax to support the CTA as well as a failing commuter rail system (which was unified and named Metra). Privately owned and municipal bus routes in the suburbs were similarly united under the name of Pace (1983). The RTA has revitalized the system and even expanded it, notably into areas northwest and southwest of the city not previously served. In addition, there is one independent commuter rail line, the heavily subsidized South Shore Line to South Bend, Indiana, the country’s sole surviving electric interurban line.
Occasionally, Chicagoans run the risk of being “bridged”—shut out of the Loop because bridges in the central area must be raised to allow passage of river traffic. There are several dozen movable bridges over waterways within the city. Two of the most noteworthy are the large double-deck Michigan Avenue and Outer Drive (or Link) bridges, the latter connecting the northern and southern parts of Lake Shore Drive. Although bridge raisings are now rare—confined largely to specified times to allow the passage of tall-masted sailboats—the river bustles in warmer weather with pleasure craft, sightseeing boats, and the occasional barge.
An aging remnant of Chicago’s infrastructure came to light dramatically in April 1992, when an under-river tunnel was punctured, leading to massive flooding in downtown basements. A system of freight tunnels had been constructed below Loop streets at the beginning of the 20th century to haul cargo, coal, and ashes to and from downtown buildings. Eventually abandoned after having served its original purpose, the system found new life carrying communications wiring and fell into obscurity until the flood. There are also unused remains of three vehicular tunnels downtown that were built under the river before 1900 because the river’s heavy shipping traffic so disrupted the use of the bridges.
