I played for a long time on EU and for reason I now play on NA server.  And I noticed when using the market allot of thing I can find massive amount of on the EU server I seam to find 0 of on NA server like the silver embroided Trainer´s cloth there is not a single one for sale Even Logia has 3 for sale and it seams to be like this with allot of armors and such.

So is there a special reason for it or is it becuse NA servers compared to EU is low populated ? 

Ahh i dont think this is accurate tbvh. We usually use more of the resource causing a higher demand from what i can tell nothing to do with population

Generally the meme is that there are far less lifeskillers on NA than on EU, which leads to higher demand on consumables like caphras, and many elixirs, as well as lifeskill products like silver embroidered clothes. In return, there are more "whales" that supply the marketplace with outfits.

IIRC the population on NA is slightly smaller, but not by a large margin, so it won't have too much of an influence. 

There is a lot of demand for items, so they disappear off the market fast. For example, I will craft outfits and toss them on the market on the weekends, where there are already many pre-orders at max value. When I get accessory drops, even when the list is full, I can put them at max value and they'll sell within 10-20 min. Some accessories are too common, but others get sold to max-order pre-orders or will disappear quickly because a lot of players enhance their own stuff. They need lots of stuff to blow up!
