The Hispanic population of the United States is growing fast and changing fast. The places Latinos live, the jobs they hold, the schooling they complete, the languages they speak, even their attitudes on key political and social issues, are all in flux. They now constitute this country's largest minority, but they are not an easily identified racial or ethnic group. Rather, they are defined by shared elements of Latin American ancestry and culture. In this report, the Pew Hispanic Center examines Hispanic demographic trends and labor market and educational outcomes; the center also analyze the diverse attitudes, values, beliefs and language patterns of the Latino population. [This report was originally published as a chapter in "Trends 2005," a Pew Research Center reference book.]
