Phew, I don't know what it is, but the only imperical data I can find is between North America, Japan, and China.

I was able to find a couple of things so people can consider this topic more "global."

"Unlike in the U.S., "anime" and "manga" in Japan are central to popular culture and everyday life. Here is a report on this market that is expected to soon amount to Y10 trillion -- a whopping US$100 billion."

Unfortunately thisd data is from before the recession, but at the time of writing, the US market was projected to grow to twice the size of that of Europe here:

"Japanese anime is expected to grow along with the spread of new media. If the size of the Japanese market is set to "100", then the size of the U.S., European, and Asian markets are estimated to grow to "200", "100", and "50", respectively."

Again, unfortunately, things still look bad for the entire worldwide market, citing from just last year:

"In Iwata’s view, there is no room for growth since Japanese animation has reached the saturation point in the global marketplace. Due to the worldwide recession and illegal net distribution, Iwata concluded that the North American marketplace is battered, the European marketplace is in grave condition, and the Japanese companies cannot rely on the Middle East, Asia, and other regions as potential new marketplaces. He added, “as it stands, we may have to go back to the way it was in the past — back to selling Japanese animation only to the Japanese marketplace.” In order to survive in the current adverse climate, TV Tokyo is proceeding with new initiatives that include animation on American video-distribution sites. "

In order to help fix this global decline, TV Tokyo turns to American websites, with the leading western market, to help aleviate some of the losses being incurred.
