WASHINGTON (AP) - U.S. employers added just 88,000 jobs in March, the fewest in nine months and a sharp retreat after a period of strong hiring. The slowdown may signal that the economy is heading into a weak spring.The Labor Department said Friday that the unemployment rate dipped to 7.6 percent, the lowest in four years, from 7.7 percent. But the rate fell only because more people stopped looking for work. People who are out of work are no longer counted as unemployed once they stop looking for a job.
The percentage of working-age adults Americans with a job or looking for one fell to 63.3 percent in March, the lowest such figure in nearly 34 years.
Stocks plummeted after the report but narrowed their losses later in the day. The Dow Jones industrial average was down about 76 points in midafternoon trading. Broader indexes also declined.
March's job gain was less than half the average of 196,000 jobs in the previous six months. The government said hiring was even stronger in January and February than previously estimated. January job growth was revised up from 119,000 to 148,000. February was revised from 236,000 to 268,000.
Several industries cut back sharply on hiring. Retailers cut 24,000 jobs in March after averaging 32,000 in the previous three months. Manufacturers cut 3,000 jobs after adding 19,000 in February. Financial services shed 2,000.
Some economists said retailers might have held back on hiring because March was colder than normal. That likely meant that Americans bought fewer spring clothes and less garden equipment. Clothing stores shed 15,000 jobs, and building material and garden supply stores shed 10,000.
In March, average hourly pay rose a penny, the smallest gain in five months. Average pay is just 1.8 percent higher than a year earlier, trailing the pace of inflation, which rose 2 percent in the past 12 months.
"This is not a good report through and through," Dan Greenhaus, chief economic strategist at brokerage firm BTIG, said in a note to clients.
The Labor Department uses a survey of mostly large businesses and government agencies to determine how many jobs are added or lost each month. That's the survey that produced the gain of 88,000 jobs for March.
The government uses a separate survey of households to calculate the unemployment rate. This survey found that the number of people either working or looking for work fell by nearly 500,000. It was the sharpest such drop since December 2010. And the number of Americans who said they were employed dropped nearly 210,000.
The percentage of working-age adults in the labor force is a figure that economists call the participation rate. At 63.3 percent, it's the lowest since 1979. Normally during an economic recovery, an expanding economy lures job seekers back into the labor market. This time, many have stayed on the sidelines, and more have joined them.
Longer-term trends have helped keep the participation rate down. The vast generation of baby boomers has begun to retire. The share of men 20 and older in the labor force has dropped as manufacturing has shrunk.
Some who have left the job market are getting by on government aid, particularly Social Security's program for the disabled. The share of women working or looking for work has plateaued, and fewer teenagers are working.
Heidi Shierholz, an economist at the liberal Economic Policy Institute, said the labor force participation among those ages 25 to 54 - "prime age" workers - has dropped to 81.1 percent. It hasn't been lower since 1984.
Gary Burtless, senior fellow in economic studies at the Brookings Institution, noted that some Americans have likely stopped looking for work because their unemployment benefits have run out. People must be looking for a job to qualify for unemployment benefits.
"If people aren't collecting benefits, they have one less reason to be out pounding the pavement looking for a job," Burtless said.
This could be the fourth straight year that the economy and hiring have shown strength in winter and early spring, only to weaken afterward.
An intensifying European financial crisis depressed hiring in 2010 and 2011. Japan's earthquake and tsunami also disrupted U.S. manufacturing in 2011. Last year, an unusually warm winter caused employers to do more hiring earlier in the year than usual. Job gains averaged 262,000 a month from January through March last year, then fell to a pace of 108,000 in the April-June quarter.
This year, steep government spending cuts that began taking effect March 1 could have the same effect. But some economists say they expect any weakening this spring to be milder. The economy has a stronger foundation now. Housing is recovering, and consumers are spending more.
Rising home prices and near-record-level stock prices are making consumers feel wealthier. Construction firms have also added 169,000 jobs in the past six months as home building has accelerated.
"The recovery is on much better footing this year than in the last few springs, and the recovery in the housing market will do much to support growth," said Sophia Koropeckyj, an economist at Moody's Analytics.
Economists also cautioned against reading too much into a one-month slowdown in hiring. The higher revised job totals for January and February suggest that some hiring might have again occurred earlier in the year than usual. Job gains have averaged 168,000 in the past three months, close to the trend of the past two years.
Sluggish hiring could embolden the Federal Reserve to keep borrowing costs low for the long run. The Fed has said it plans to keep short-term interest rates at record lows at least until unemployment falls to 6.5 percent - and Chairman Ben Bernanke has said a 6.5 percent rate is a threshold, not a "trigger," for any rate increase. The Fed wants to see sustained improvement in the job market.
Most analysts think the economy strengthened from January through March, helped by the pickup in hiring, a sustained recovery in housing and steady consumer spending. Consumers stepped up purchases in January and February, even after Social Security taxes increased this year.
At the same time, some small businesses say they've grown more cautious about hiring. The government spending cuts could cut into sales at companies with federal contracts and at small retailers located near government facilities. And small business owners worry about increased health insurance costs next year, when the government's health care overhaul is fully implemented.
A survey released Wednesday by the National Federation of Independent Business showed that fewer small businesses plan to hire.
Some smaller employers are also wary about hiring before an expected fight over an increase in the federal minimum wage. President Barack Obama has proposed raising the minimum wage to $9 an hour from $7.25.
As federal agencies and contractors cut back in coming months, Nariman Behravesh, chief economist at IHS Global Insight, expects jobs growth to average 100,000 to 150,000 a month, down from an average 212,000 from December through February.
"The good news is that this is happening at a time when the private economy is gaining momentum," Behravesh said. He expects hiring to pick up after mid-year.
Craig Alexander, chief economist with TD Bank Financial Group (NYSE:TD) , said the economy isn't growing fast enough to generate many jobs. He expects the economy to grow around 2 percent this year, a sluggish pace. He thinks it would be growing faster, perhaps at a 3 percent annual rate, if not for the Social Security tax increase and the federal budget cuts.
"Fiscal austerity is having an impact," Alexander said.
