Difference between american and worldwide navdata?

[wyman_hd 232]

When i was updating, there were options for american, european, asian, south american, and a few other types of navdata. I'm not sure what the difference is between all of these, but i chose to use worldwide navdata. 

But what's the difference between all of these?
