Increasing housing prices and the stock market's posting all-time highs haven't helped the plight most Americans. The average U.S. household has recovered only 45 percent of the wealth they lost during the recession, according to a report released yesterday from the Federal Reserve Bank of St. Louis. This finding is a very different picture than one painted in a report earlier this year by the Fed that calculated Americans as a whole had regained 91 percent of their losses. The earlier number is based on aggregate household-net-worth data [which] isn't adjusted for inflation, population growth or the nature of the wealth. Much of recovery in net worth is because of the stock market, which means most of the improvement has been a boon only to wealthy families. Clearly, the 91 percent recovery of wealth losses portrayed by the aggregate nominal measure paints a different picture than the 45 percent recovery of wealth losses indicated by the average inflation-adjusted household measure," the report said. "Considering the uneven recovery of wealth across households, a conclusion that the financial damage of the crisis and recession largely has been repaired is not justified," the researchers said. Almost two-thirds of the increase in aggregate household wealth is due to rising stock prices. This has disproportionately benefited the richest households: About 80 percent of stocks are held by the wealthiest 10 percent of the population.
