New York's position at the mouth of the Hudson River enabled rapid development
of the port area and associated industries. It's importance increased in 1825,
with the opening of the Erie Canal, allowing the city became the gateway between
the Great Lakes and the agricultural Great Plains and to overtake Boston and
Philadelphia in economic terms. Immigrants from central Europe and the Orient
contributed to the development of a thriving textile industry during the 19th
century. The city experienced a boom in the 1920s, as evidenced by the number
of sky-scrapers and grand public buildings dating from this era. The stock market
crash of 1929 and an overall economic downturn led to the Great Depression of
the 1930s. Unemployment in some areas soared to 20% and in many sectors took
decades to fully recover.
Since the 1950s, port activity in New York Harbour has all but ceased and freight
is now handled at Port Newark-Marine Terminal in New Jersey, at the north of
Staten Island. During the 1960s and 70s, a crisis hit the industrial areas of
the Bronx and Queens and many factories, struggling against competition from
overseas, closed down or relocated their operations. Between 1953 and 1992,
New York lost some 700,000 jobs in the industrial sector. Recent years have
seen something of a renaissance, with industry centred on printing, chemicals,
textiles and electronics. Today, there are over 230,000 jobs in New York's industrial
sector.
New York is home to the headquarters of many international companies. The United
Nations is based in New York, as is the head office of the charity UNICEF. The
New York Stock Exchange is the largest in the world in terms of dollar volume
and the city has a deserved reputation as a financial centre, housing many major
banks and financial institutions. The New York film industry is the second largest
in the US, after Hollywood. The estimated Gross Product of New York City, at
$450 billion, is higher than the GDP of Switzerland and the Gross State Product
of the New York metropolitan region exceeds that of every U.S. state except
California.
