A burst of hiring last month added 236,000 U.S. jobs and reduced the unemployment rate to 7.7 percent from 7.9 percent in January. The robust gains suggested that the economy can strengthen further despite higher taxes and government spending cuts.

The February jobs report issued Friday provided encouraging details: The unemployment rate is at its lowest level in four years. Job growth has averaged more than 200,000 a month since November. Wages rose. And the job gains were broad-based, led by the most construction hiring in six years.

The unemployment rate had been stuck at 7.8 percent or above since September. The rate declined last month because the number of unemployed fell 300,000 to just over 12 million, the fewest since December 2008.

More than half the decline occurred because 170,000 of the unemployed found jobs. An additional 130,000 stopped looking for work. People who aren’t looking for jobs aren’t counted as unemployed.

The unemployment rate is calculated from a survey of households. The job gains are derived from a separate survey of employers.

Stock prices rose as trading began at 9:30 a.m. Eastern time, an hour after the jobs report was released. Another day of stock gains would give the Dow Jones industrial average its fourth straight record close.

Employers did add slightly fewer jobs in January than the government had first estimated. Job gains were lowered to 119,000 from an initially estimated 157,000. Still, December hiring was a little stronger than first thought, with 219,000 jobs added instead of 196,000.

Robust auto sales and a steady housing recovery are spurring more hiring, which could trigger more consumer spending and stronger economic growth. The construction industry added 48,000 in February; it’s added a solid 151,000 since September. Manufacturing gained 14,000 jobs last month and 39,000 since November.

Retailers added 24,000 jobs, a sign that they anticipate healthy consumer spending in the coming months. Education and health services gained 24,000. And the information industry, which includes publishing, telecommunications and film, added 20,000, mostly in the movie industry.

The economy is also benefiting from the Federal Reserve’s drive to keep interest rates at record lows. Lower borrowing rates have made it easier for Americans to buy homes and cars and for companies to expand.
