Spending on construction tumbled 0.6% in June, with declines spread evenly across the private and public sectors, the Commerce Department said Monday. That was well below forecasts. Economists surveyed by Econoday had expected a 0.6% increase. Outlays are still 6.2% higher for the first six months of the year compared to the same period in 2015. Housing seems to be holding its own: private residential construction was up 2.6% during the month, making it one of the strongest categories.
