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 16% and outbound up 8%.
The 2nd graph is the monthly data (with strong seasonal pattern). For the month of April, loaded inbound traffic was up 7% compared to April 2010, and loaded outbound traffic was up 8% compared to April 2010. Even with the decline in April, exports are near the pre-recession peak.
This suggests the trade deficit with China (and other Asians countries) probably increased in April.
