U.S. homebuilding surged to a 13-year high in December as activity increased across the board, suggesting the housing market recovery was back on track amid low mortgage rates, and could help support the longest economic expansion on record.

Housing starts jumped 16.9% to a seasonally adjusted annual rate of 1.608 million units last month, the highest level since December 2006. The percentage gain was the largest since October 2016. Data for November was revised higher to show homebuilding rising to a pace of 1.375 million units, instead of advancing to a rate of 1.365 million units as previously reported.

Economists polled by Reuters had forecast housing starts would increase to a pace of 1.375 million units in December.

Housing starts soared 40.8% on a year-on-year basis in December. An estimated 1.290 million housing units were started in 2019, up 3.2% compared to 2018.

Building permits fell 3.9% to a rate of 1.416 million units in December after hitting their highest level in more than 12-1/2 years in November.
