New Census Data Confirms the Rich Getting Richer and Everyone Else, Poorer

The new Census Bureau report on income is out, and the New York Times has some interesting analyses. Here are a few of them summarized:

For the first time since the Census has been keeping records, median income is less than it was ten years ago. And even though the top quintile of workers' incomes increased, the decrease in the other four quintiles was significant enough to make the median income in 2008 less than it was in 1998. In short, the rich have gotten richer, and everyone else, poorer.

In terms of the relation between family income and SAT test scores, the Times analyis shows the statistical relation a monstrous direct correlation (.95). This same correlation, by the way, can be found in any set of state test scores for elementary school children, too. Poor kids do worse on high-stakes standardized tests, so let's keep them poor and contained by using these tests to determine who gets a chance for the best teaching, the best colleges, and the best jobs. Simple. The rest will get the corporate welfare apartheid charter schools with minimally-qualified missionaries from Teach for America, along with no libraries, no art, music, athletics, or even cafeterias. And thus, The New Eugenics in Action.

As family income and wealth goes, so go the test scores, so let's blame, once again, the schools and the teachers for the flat or diminishing test scores, rather than the corporate exporters of jobs over the past decade or the greed of CEOs or the enemies of workers' rights or the anti-educational curriculums of the testocrats.

Much has been written about the relationship between SAT scores and test-takers’ family income. Generally speaking, the wealthier a student’s family is, the higher the SAT score.

Let’s take a look at how income correlated with scores this year. About two-thirds of test-takers voluntarily report their family incomes when they sit down to take the SAT. Using this information, the College Board breaks down the average scores for 10 income groups, each in a $20,000 range.

First, here are the individual test sections:

Here are all three test sections next to each other (zoomed in on the vertical axis, so you can see the variation among income groups a little more clearly):

A few observations:

• There’s a very strong positive correlation between income and test scores. (For the math geeks out there, the R² for each test average/income range chart is about 0.95.)
• On every test section, moving up an income category was associated with an average score boost of over 12 points.
• Moving from the second-highest income group and the highest income group seemed to show the biggest score boost. However, keep in mind the top income category is uncapped, so it includes a much broader spectrum of families by wealth.
