Latinos are now the region s biggest minority
CHICAGO S recovery from decline is measured not just in jobs and dollars, but also in people. In America, at least,
a city is considered moribund if its population is not growing. By that measure, greater Chicago is prospering; but
the story is more complicated than it seems.
The 2000 census was greeted with delight by the city. It showed that, after decades of losing people both to the
suburbs and to other parts of the country, it had increased its population by 4% since 1990. The vast conurbation
around Chicago—what the Census Bureau calls the Chicago-Naperville-Joliet metropolitan area, which includes bits
of Indiana and Wisconsin—had grown by 11.2%. And though the suburbs had been the big gainers (up 14%), even
the cities (towns of over 100,000 people) in that conurbation had grown by 6.3%. Urban life was evidently
flourishing.
The trend, though, has not been sustained. In 2000-04, the metropolitan area grew by just 3%, less than the rate
of natural increase. The big towns lost population (by 0.1%), whereas the suburbs continued to grow (by 4.6%).
Chicago itself shrank by over 1%.
The shrinkage in the towns would have been much greater, and the growth in the suburbs much smaller, but for
one thing immigration, nearly all of it fuel dispenser by Latinos. Between 1970 and 2004, Latinos accounted for 96% of the
growth of the six counties fuel dispenser round Chicag fuel dispenser o. The average increase during the 1990s was 57,000 people a year.
The accompanying changes are already dramatic. In the city itself, more than one person in four is now a Latino,
and Chicago has more Hispanics than any other city but Los Angeles. With such neighbourhoods as Greektown,
Little Italy and Ukrainian Village, Chicago has never disguised its long history as a home for immigrants, many of
whom cluster together for decades after their arrival. Native-born migrants have come, too, notably Midwes
