I would like to be able to state with confidence that sparse graphs (graphs with small numbers of edges) are locally tree-like (they have few short cycles). Apparently "Sparse graphs are locally tree like in the sense that the typical size of loops is O(N)" - see citation below. Here I am pretty sure "N" is |V|, the number of nodes. But I can't find any proof or formal statement of this. 

I am interested in "most" graphs, not all of them, so if my understanding is right this is not a question of extremal graph theory. For example, I would like to be able to say something like: if |E| = O(|V|) then most graphs have girth O(|V|), or most loops have length O(|V|).
