The Chicago-Naperville-Jolliet Metropolitan Statistical area
has over 1.7 million residents of Hispanic/Latino origin according
to estimates from the American Community Survey, 2005 (ACS05).
Nearly one in five area residents is of Hispanic/Latino origin,
making the area the third largest concentration of Hispanics/Latinos
in the US after Los Angeles and New York. Nearly 30% of the estimated
2,701,926 residents of the city of Chicago are of Hispanic/Latino origin
according to ACS05. There are 778,234 Hispanics/Latinos in the city of
Chicago proper with Mexican/Mexican Americans being the largest subgroup
(73%, n=564,853), followed by Puerto Ricans (15%, n=113,924), and other
Hispanics/Latinos (13%, =99,467) (ACS05).
While recent years have seen a trend of urban gentrification in some
traditionally Latino neighborhoods in the city and a corresponding
trend of Hispanic/Latino out-migration to the suburbs, there remain
numerous neighborhoods with substantial concentrations of Hispanics/Latinos.
The targeted area for the Chicago site is composed of such ethnically
diverse neighborhoods with several that have been majority Hispanic/Latino
for decades as well as others that were traditionally White/European-immigrant
which have experienced Hispanic/Latino in-migration only recently.
