Blockchain size right now is 6073 MB, and will be much larger on the next year because of the bitcoin population is growing larger and larger every day. Expect that in the next year, blockchain would be larger than it's size right now since the bitcoin population is rapidly growing each day that passed by because bitcoin really helps people in many ways.
du -sh ~/.bitcoin/
117G /home/[snip]/.bitcoin/
Where did you get the number 6073 Mb if i might ask? Maybe you've got a pruned blockchain?
Btw: the size of the blockchain has nothing to do with how many people use bitcoin, and everything to do with the size and number of transactions.
