In some cases it's that it is too hard to vote. The locations change, people are removed from rolls, after moving, you have to re-register etc. 

In places like NYC where voting is frankly pretty easy, often there isn't much to vote about. Close elections are rare, so a lot of the low turn out is from very blue or red areas where showing up doesn't change much.
