Beginning in the 20th century, much internal migration took place within the state. Higher- and middle-income whites moved to the suburbs, leaving low-income whites and African Americans within the central cities. Likewise, much economic activity, notably manufacturing and the headquarters of corporations, also moved to the suburbs. This movement of people and economic activity resulted in an urban crisis familiar across the United States: an increasing need for the cities to combat crime and other symptoms of poverty, coupled with the removal of the social and economic resources to do so. Although New York City’s population began rebounding in the late 20th century and the economic strength of the state’s large metropolitan areas generally has been growing, the cities’ poor increasingly have been unable to participate in the prosperity and seem likely to slip still farther behind.

Agriculture

Farmland covers nearly one-third of the state’s land area; about three-fifths of New York’s farmland is cropland. Dairying is the most important source of farm income, providing more than one-half of the total. Other important sources of farm income are poultry and eggs, livestock products, fruits, vegetables, and field crops. The state raises a variety of horticultural specialties, including nursery products, crops grown in greenhouses, flower bulbs, and seeds, and it competes with Vermont in the production of maple sugar. The fruit and vegetable farms supply the food-processing industry with such products as apples, cherries, peaches, currants, strawberries, tomatoes, peas, beans, sweet corn, and cabbage. There is also a long-standing winemaking tradition that began commercially in the state in the early 1800s. New York is one of the country’s largest wine producers; particularly well known for their wines are the Hudson valley and Finger Lakes regions.

Manufacturing, services, and taxation

A declining proportion of New York’s workforce is engaged in manufacturing activities. In 1947 more than one-third of the state’s employed population was in manufacturing, but by the early 21st century that proportion had dropped to only about one-tenth of the total. New York’s service and manufacturing economy remains diverse. It includes financial services; printing and publishing; fashion, apparel, and textiles; food processing; optics and imaging instruments; computer hardware and software; biomedical and chemical products; industrial, electric, and electronic machinery and systems; and transportation equipment and distribution services.

There is some economic specialization within different parts of the state. Services and activities related to finance, insurance, and real estate are more concentrated in the New York City metropolitan area than in upstate New York. Buffalo is strong in heavy industry, while Rochester dominates the manufacture of photographic and optical equipment and is primarily responsible for the state’s strong position in instrument production.

Syracuse ranks high in the state in the production of primary metals, machinery, and paper and allied products, as well as in educational employment. The Utica-Rome area specializes in machinery and primary metals, while the Albany-Troy-Schenectady area is strong in the production of paper and allied products. Albany, as the state capital, leads in government employment. Binghamton, the site of a forerunner of the International Business Machines Corporation (IBM), has a concentration of employment in the computer and business-machine field.

New York state residents pay one of the highest per capita tax rates in the United States, a system made possible by the state’s relatively healthy economic base. The state imposes income, sales, business, and excise taxes. Local revenues are derived mainly from property and sales taxes. The broad state base plus the widespread use of local sales taxes allows New York to rely less on local property taxes than do other large or heavily populated states. Since the late 20th century, the size of New York’s government has been reduced through consolidation and privatization, prompting a series of tax cuts designed to make the state more competitive economically.

Transportation

A great part of New York’s economic advantage is its location on important natural transportation routes and facilities that connect urban centres within and without the state.

The Erie Canal, opened in 1825, tied New York City and its port to Buffalo and the westward-expanding country. The main railroad system followed the route of the canal, with feeder lines that jutted north and south into the remainder of the state. After World War II the limited-access Thruway stretched from New York to the Pennsylvania state line, passing through Albany, Utica, Syracuse, Rochester, and Buffalo. The basic paths of these main transportation routes are not substantially different from those that were used by the state’s original settlers.

With the completion in 1918 of the New York State Barge Canal System (now called the New York State Canal System), which incorporated the old Erie Canal, New York had the country’s most extensive inland waterway system. The canal system stretches some 520 miles (840 km) and has more than 50 locks. Although it is an important means for moving bulk goods—particularly petroleum products, a major share of the freight hauled—the tonnage it carries annually has dropped considerably.

The railways first challenged the supremacy of the canal as a carrier of goods. Beginning in the mid-19th century with the establishment of the New York Central Railroad, a system was built that tied New York’s major cities to Chicago, Boston, Montreal, and other urban centres. Although the number of passengers carried has declined, the railroads remain important handlers of freight. Much of this freight originates via the facilities of the Port Authority of New York and New Jersey, still one of the largest and busiest port complexes in the United States, handling about one-tenth of all the country’s imports and a large proportion of all immigrants to the United States.

Central to the highway system are the limited-access highways. The Thruway connects at Albany to the Adirondack Northway, which extends northward to Canada. In central New York a major highway runs from the Pennsylvania state line to Canada, passing through Binghamton, Syracuse, and Watertown. At Syracuse this route intersects with the Thruway, maintaining the city as a transportation hub and accounting in large part for its economic viability. Another limited-access expressway extends across the southern tier of the state. On Long Island a set of east-west highways ties the island to New York City, New England, and upstate New York.

The New York City metropolitan area, with its combination of subways, buses, and railroads, has the most complex commuter system in the country. The vast New York transit system provides intracity passenger transport. Commuter railroads serve suburban Long Island, Westchester county, New Jersey, and Connecticut. Many of these transportation networks were brought under the control of a single agency, the Metropolitan Transportation Authority, in 1968.

The three largest airports in the New York City metropolitan area are John F. Kennedy International, La Guardia, and Newark Liberty International, in New Jersey. Other airports providing national and international service are located in Albany, Buffalo, Islip, Rochester, and Syracuse, among others, and the state has a number of regional and county airports.
