A new study shows Hispanics now make up the largest group of children living in poverty in the United States. According to the Pew Hispanic Center, some 6.1 million Hispanic children are poor, compared with five million white children and 4.4 million black children. The poverty rate for Hispanic children was 35 percent; for black children, 39 percent; and for white children, 12 percent. Analysts say the figures underscore conclusions that Hispanics have been the hardest-hit ethnic group during the economic recession.
