Click on graph for larger image in graph gallery.To remove the strong seasonal component for inbound traffic, this graph shows the rolling 12 month average.
On a rolling 12 month basis, inbound traffic is up 18% and outbound up 11%.
The 2nd graph is the monthly data (with strong seasonal pattern). For the month of January, loaded inbound traffic was up 13% compared to January 2010, and loaded outbound traffic was up 12% compared to January 2010 - but down compared to December 2010. This suggests the trade deficit with China (and other Asians countries) probably increased in January.
