Home construction is near a three-year high. And factory output has risen in three of the year's first four months.
The data released Wednesday suggest growth in the April-June quarter is off to a good start, helped by falling gas prices and solid hiring gains. Fears of a spring slump are easing.
"It's all very encouraging," said Paul Ashworth, chief U.S. economist at Capital Economics. "Things look good at the moment."
Builders broke ground in April at a seasonally adjusted annual pace of 717,000 homes, the Commerce Department said. That nearly matches January's pace, the best since October 2008.
Construction rose for both single-family homes and apartments.
Some economists have noted that a warm winter led companies to move up some hiring and accelerate other activity — including homebuilding — that normally wouldn't occur until spring. That gave the appearance that the economy had strengthened in January and February and weakened in March.
But Ashworth noted that the overall trend in housing starts has been running at roughly the same annual pace — approximately 700,000 — over the past six months. That's 100,000 more on average than the pace for the previous six months.
Ashworth said the higher level suggests demand is increasing and the mild winter had less effect than some economists had thought.
"We expect starts to strengthen further this year," Ashworth wrote in a note to clients.
Even with the gains, the rate of construction for all homes is only about half the 1.5 million annual pace that most economists consider healthy. But the increase, along with rising builder confidence and stronger job growth, is a sign that the home market may finally be starting to recover nearly five years after the housing bubble burst.
Single-family home construction is now 39 per cent higher than its recession low. And developers are also anticipating more sales. Permits for single-family home construction rose 2 per cent last month.
The growth in single-family home construction is important because those homes make up roughly 70 per cent of the market. Since the recession, homeownership has declined while demand for apartments has surged.
Economists say continued job gains could quickly reverse that trend.
"Homebuilders are reporting stronger demand," Ian Shepherdson, an economist at High Frequency Economics, said in a note to clients. "And while rental demand means the multi-family sector is much stronger than single family, that will change as the labour market improves further."
U.S. manufacturing, one of the strongest areas of the economy since the recession ended nearly three years ago, also rebounded in April after a March lull.
Factory output is now 18.3 per cent higher than its low hit in June 2009, the month the recession ended. It's only 6.1 per cent below its pre-recession peak.
Factories are busier in part because automakers are selling more cars and trucks. Half of April increase in factory output reflected a 3.9 per cent jump in the production of motor vehicles and parts. That was the fifth straight gain at auto plants.
Production also rose at a wide range of companies in April, from makers of computers and electronics to aerospace and furniture factories.
The modest gain shows that U.S. manufacturers aren't cutting back in the face of Europe's financial crisis and slower growth in China.
Faster output at U.S. factories has been a key reason employers have added 1 million jobs over the past five months. It's also helped lower the unemployment rate from 9.1 per cent in August to 8.1 per cent last month.
Manufacturing companies have added 167,000 jobs in that stretch. That's roughly 17 per cent of the job gains, even though manufacturing represents less than 10 per cent of the economy.
More jobs, along with record-low mortgage rates and low home prices, are making home buying more attractive to some Americans.
And gas prices have dropped in the past month after surging earlier this year. So consumers have more money for other purchases. The average price of a gallon of gas was $3.73 on Wednesday, according to AAA. That's 18 cents less than a month ago.
Some hurdles to a smooth recovery remain: Builders are struggling to compete with deeply discounted foreclosures and short sales. (Short sales occur when a lender accepts less than what's owed on a mortgage.)
And many would-be buyers are struggling to qualify for home loans or can't afford larger down payments that banks require.
Though new homes represent just 20 per cent of the overall home market, they have an outsize impact on the economy. Each home built creates an average of three jobs for a year and generates about $90,000 in taxes, according to the National Association of Home Builders.
