WASHINGTON >> The U.S. economy showed last month why it remains the envy of industrialized nations: In the face of tax increases and federal spending cuts, employers added a solid 165,000 jobs in April — and far more in February and March than anyone thought.

The hiring in April drove down the unemployment rate to a four-year low of 7.5 percent and sent a reassuring sign that the U.S. job market is improving.

The economy is benefiting from a resurgent housing market, rising consumer confidence and the Federal Reserve’s stimulus actions, which have helped lower borrowing costs and lift the stock market.

The stock market soared after the Labor Department issued the April jobs report Friday. The Dow Jones industrial average closed up 142 points, or nearly 1 percent, to a record 14,973. It briefly broke 15,000 for the first time.

Coming after a poor March jobs report and some recent data showing economic weakness, the April figures helped ease fears that U.S. hiring might be slumping for a fourth straight year.

"Businesses haven’t lost confidence yet," said Sung Won Sohn, an economist at the Martin Smith School of Business at California State University. "Consumers are feeling better. The decent employment gains will add to the optimism and help lift future spending."

The Labor Department revised upward its estimate of job gains in February and March by a combined 114,000. It raised its estimate for February job gains to 332,000 from 268,000 and for March to 138,000 from 88,000.

Excluding May 2010, when the figures were skewed by temporary Census hiring, February’s gain was the most since November 2005.

The economy has created an average of 208,000 jobs a month from November through April — well above the monthly average of 138,000 for the previous six months.

The stronger job growth suggests that the federal budget cutting "does not mean recession," said John Silvia, chief economist at Wells Fargo. "It does not mean a dramatic slowdown."

The unemployment rate edged down from 7.6 percent in March and has fallen 0.4 percentage point since the start of the year, though it remains high. To help spur borrowing, the Fed has said it plans to keep its benchmark interest rate at a record low near zero at least until unemployment falls to 6.5 percent.

One cautionary note in the employment report: Most of the biggest job gains were in lower-paying fields, such as hotels and restaurants, which added 45,000 jobs, and retail stores, which added 29,000.

By contrast, construction companies and governments cut jobs. Manufacturing employment was flat.

Some higher-paying sectors added workers. For example, professional and technical services, which include jobs in accounting, engineering and architecture, added 23,000 jobs. Education and health services gained 44,000.

Average hourly pay rose. But because employees in the private sector worked fewer hours, average weekly paychecks declined.

But over the past year, total pay after adjusting for inflation is up a healthy 2.1 percent, economists said. That should help boost consumer spending in coming months.

The job growth is occurring while the U.S. economy is growing modestly but steadily. It grew at a 2.5 percent annual rate in the January-March quarter.
