One explanation is the disparity in income that exists between African Americans and Whites. This school of thought argues that the origin of this "wealth gap" is the slavery and racism that made it extremely difficult for African-Americans to accumulate wealth for almost 100 years after slavery was abolished. A comparable history of discrimination created a similar gap between Hispanics and Whites. This results in many minority children being born into low socioeconomic backgrounds, which in turn affects educational opportunities.[191] Another explanation has to do with family structure. Professor Lino Graglia has suggested that Blacks and Hispanics are falling behind in education because they are increasingly raised in single-parent families.[192][193] Other explanations offered for the racial achievement gap include: social class, institutional racism, lower quality of schools and teachers in minority communities, and civil injustice. Most authors mention several such factors as influential on outcomes, both in the United States[194] and worldwide.[195] International comparison In the OECD's Programme for International Student Assessment 2003, which emphasizes problem solving, American 15-year-olds ranked 24th of 38 in mathematics, 19th of 38 in science, 12th of 38 in reading, and 26th of 38 in problem solving.[196] In the 2006 assessment, the U.S. ranked 35th out of 57 in mathematics and 29th out of 57 in science. Reading scores could not be reported due to printing errors in the instructions of the U.S. test booklets. U.S. scores were behind those of most other developed nations.[197] US fourth and eighth graders tested above average on the Trends in International Mathematics and Science Study tests, which emphasizes traditional learning.[198] The United States is one of three OECD countries where the government spends more on schools in rich neighborhoods than in poor neighborhoods, with the others being Turkey and Israel.[199] Poor education also carries on as students age. The Organization for Economic Co-operation and Development's (OECD) administer another survey called the Survey of Adult Skills, which is a part of its Programme for the International Assessment of Adult Competencies (PIAAC). In the most recent survey done in 2013, 33 nations took part with adults ages 16 to 65 in numeracy, literacy and problem-solving. The Educational Testing Service (ETS) found that millennials – age from teens to early 30s – scored low. Millennials in Spain and Italy scored lower than those in the U.S., while in numeracy, the three countries tied for last. U.S. millennials came in last among all 33 nations for problem-solving skills.[200] Wider economic impact Current education trends in the United States represent multiple achievement gaps across ethnicities, income levels, and geography. In an economic analysis, consulting firm McKinsey & Company reports that closing the educational achievement gap between the United States and nations such as Finland and Korea would have increased US GDP by 9-to-16% in 2008.[201] Narrowing the gap between white students and black and Hispanic students would have added another 2–4% GDP, while closing the gap between poor and other students would have yielded a 3-to-5% increase in GDP, and that of under-performing states and the rest of the nation another 3-to-5% GDP. In sum, McKinsey's report suggests,
