The American Trucking Associations' advanced seasonally adjusted For-Hire Truck Tonnage Index fell 3.6 percent in January after surging a revised 6.2 percent in December.
ATA recently revised the index back five years, which resulted in a slightly better 2006 than previously reported, although the index was still down for the year. ATA's index fell 1.7 percent compared with 2005 rather than the originally reported 3.0 percent drop. December's tonnage level, meanwhile, actually increased 6.2 percent instead of a previously reported 3.8 percent. ATA annually revises the index as part of its calculation for the upcoming year's seasonal factors.
On a seasonally adjusted basis, the tonnage index fell to 110.9 (2000 = 100) in January from 115.1 in December. Additionally, the index decreased 5.0 percent versus a year earlier, marking the seventh consecutive year-over-year decline. The not seasonally adjusted index advanced 6.5 percent from December to 108.0.
