" Between 2000 and 2005, the Hispanic population increased at an annual rate of 3.7 percent, no less than 14 times the growth rate for whites, and more than three times the black rate. This increase was due both to high birthrates and to immigration of about 800,000 Hispanics every year.
Much of that immigration was illegal. The Pew Hispanic Center estimated in 2009 that 12.7 million Mexican citizens were living in the United States in 2008, and that they accounted for 60 percent of the 11.9 million or so illegal immigrants in the country. The center has estimated that other Hispanics account for another 20 percent of illegal immigrants.
Most Americans believe that a willingness to learn English is a prerequisite to full participation in American life, but this does not appear to be a high priority for many Hispanics. According to a 2006 poll conducted by Investor’s Business Daily, 81 percent of Hispanics spoke mostly or only Spanish at home.
Even Hispanics who are comfortable in English prefer Spanish; according to a poll by P.C. Koch, nearly 90 percent of bilingual Hispanics get their news exclusively from Spanish-language sources.
In 2003, 44 percent of Hispanics did not speak and read English well enough to perform routine tasks, up from 35 percent in 1992. English illiteracy therefore increased for Hispanics during the decade, whereas it declined for every other major population group. "
