MEGAN MCARDLE: Department of Awful Statistics: Income Inequality Edition. “To put it another way, the apparent clustering of income along the rich right tail of the distribution is just an artifact of the way that the Census presents the data. If they kept running through $5,000 brackets all the way out to A-Rod, the spreadsheet would be about a mile long, and there would only be a handful of people in each bracket. So at the high end, where there are few households, they summarize. Meanwhile, there’s no evidence that the middle class is getting poorer.”
