The slight rise in median household income, to $46,326, is the first in six years. That’s the good news. But the rest of the Census Bureau report makes for grim reading. For one thing, wages are actually shrinking relative to inflation, which suggests that incomes are rising only because more household members are working at more lousy jobs. The number of people without health insurance rose slightly, to a record 46.6 million. So did the number of uninsured children. The proportion of Americans living in poverty held roughly steady, at 12.6 percent, but of that group nearly half were really poor, earning less than half of the poverty-line cutoff of $20,000, ’the highest such percentage ever recorded,’ an analyst tells the NYT.
