Both nonfarm payroll employment, at 138.1 million, and the unemployment rate, at 4.9 percent, were essentially unchanged in January, the Bureau of Labor Statistics of the U.S. Department of Labor reported. The small January move- ment in nonfarm payroll employment (-17,000) reflected declines in construction and manufacturing and job growth in health care. Average hourly earnings rose by 4 cents, or 0.2 percent, over the month.
