(RTTNews) - Personal income in the U.S. increased by slightly less than anticipated in the month of February, according to a report released by the Commerce Department on Friday. Reflecting the continued impact of the recent government shutdown, the Commerce Department also released data on personal spending in January but not February. A reading on inflation said to be preferred by the Federal Reserve showed the annual rate of core consumer price growth slowed to 1.8 percent in January from 2.0 percent in December.
