Over the last seven months, the tonnage index grew a total of 6.5 percent. The non-seasonally adjusted index, which represents the change in tonnage actually hauled by the fleets before any seasonal adjustment, equaled 111.3 in April, down 4.4 percent from the previous month.
Compared with April 2009, SA tonnage surged 9.4 percent, which was the fifth consecutive year-over-year gain and the largest increase since January 2005. Year-to-date, tonnage is up 6 percent compared with the same period in 2009.
ATA Chief Economist Bob Costello says that the latest tonnage reading fits with a sustained economic recovery. “Truck tonnage volumes continue to improve at a solid, yet sustainable, rate,” Costello says. “Tonnage is being boosted by robust manufacturing output and stronger retail sales. For most fleets, freight volumes feel better than reported tonnage because the supply situation, particularly in the truckload sector, is turning quickly.”
ATA calculates the tonnage index based on surveys from its membership. The report includes month-to-month and year-over-year results, relevant economic comparisons and key financial indicators. The baseline year is 2000.
