Book excerpt: Since late 2001 more than fifty percent of the babies born in California have been Latino. When these babies reach adulthood, they will, by sheer force of numbers, influence the course of the Golden State. This essential study, based on decades of data, paints a vivid and energetic portrait of Latino society in California by providing a wealth of details about work ethic, family strengths, business establishments, and the surprisingly robust health profile that yields an average life expectancy for Latinos five years longer than that of the general population. Spanning one hundred years, this complex, fascinating analysis suggests that the future of Latinos in California will be neither complete assimilation nor unyielding separatism. Instead, the development of a distinctive regional identity will be based on Latino definitions of what it means to be American.
