Intuitively, a child's academic performance is likely higher if he or she has highly educated parents, and lower if the child has less educated parents. A new report confirms that's true, but reveals that American children of poorly educated parents do a lot worse than their counterparts in other countries.
Income mobility just within the U.S. has significantly declined since the mid-90s, according to a report this month by the Boston Federal Reserve. In recent years, families were more likely to stay within their income class than before -- the rich are staying rich, and the poor and middle-class are struggling to move up the economic ladder.
But the Pew Economic Mobility Project takes it a step further by asking the question, "Does America promote mobility as well as other nations?" Researchers in 10 countries took to analyzing socioeconomic advantage as a function of parental education.
Researchers found that a child's economic and educational status is more affected by parental education than in any other country studied.
Using a basic metric, researchers studied performance gaps on vocabulary tests among five-year-olds with highly educated parents, moderately educated parents and poorly educated parents. Among the English-speaking countries studied, the American gap between children with highly educated parents and poorly educated parents was the widest, while the Canadian gap proved to be the most narrow.
That disparity carries on to later years as well. The difference between the academic achievement advantage for adolescents with highly educated parents and the academic achievement disadvantage for adolescents with poorly educated parents is a staggering 85 percentage points. This is second only to Germany's advantage-disadvantage gap of 86.9 percentage points.
A report out last month by the National Center for Education Statistics provide more context for EMP's findings. In 2009, the most recent year for which data is available, the dropout rate for low-income students was five times greater than their high-income counterparts -- 7.4 percent compared with 1.4 percent.
FIGURE 2 NOTE: Scores were standardized so that comparisons could be made across countries where children with middle-educated parents were considered to be average. The scores were then converted from standard deviation differences to percentiles using a z table. The gap in children's percentile scores between those with high- and low-educated parents is statistically significantly larger in the United States than in each of the other countries, and it is statistically significantly smaller in Canada than in the UK.
