The United States is recovering slowly from a deep recession and many sectors of the economy have yet to show clear signs of improvement, dpa quoted a regional survey as releasing by the Federal Reserve today. Most parts of the country said their economies had stabilized or improved slightly since the Fed"s last Beige Book survey in September. But the US central bank said businesses typically qualified the recovery as very limited. Residential housing and manufacturing sectors showed signs of improvement. But consumer demand remains mixed, labour markets are weak and the commercial real estate sector is still deteriorating. "Reports of gains in economic activity generally outnumber declines, but virtually every reference to improvement was qualified as either small or scattered," the Fed"s report said. The United States is believed to have pulled out of its worst recession in decades over the summer months. But unemployment remains at a 28-year high of 9.8 per cent and could well rise above 10 per cent in 2010.
