Is U.S. Economic Mobility RISING?

Using...two National Longitudinal Survey data sets, I can compare children born between 1962 and 1964 to children born between 1980 and 1982, observing their parents' incomes when they were 14 to 16 and their own incomes twelve years later when they were 26 to 28.

In contrast to [President Obama's and other's claims] of declining mobility, I found that upward mobility from poverty to the middle class rose from 51 percent to 57 percent between the early-'60s cohorts and the early-'80s ones. Rather than assert that mobility has increased, I want to simply say - at this stage of my research (which is ongoing) - that it has not declined.

If I include households that reported negative or no income, the rise in upward mobility I find is only from 51 percent to 53 percent, which is not a statistically meaningful increase. But the data provide absolutely no evidence that economic mobility declined, whereas the president said it had fallen by ten percentage points.
