Horde population?

Just curious what the Horde population is like, most of the time I see between 3-16 Alliance (not counting ‘Steel’ guild which is only 5 people around level 47 now) with few low levels on.
Just curious if the Horde has the same problem.
I also have never seen another Alliance or Horde from Angerforge in any BG (WSG) I have joined.
