Paste below lines in EXCEL, and change the data from Text to column ("," is used as separator value).
2007* means all the numbers against this year are only 33% of total PERM approval of that year.
** indicates PERM APPROVED multiplied by 2.25 to account for all derivatives:
Year,Total,ROW,Retro,India,EB3-ROW**,EB2-ROW**,EB3-Retro**,EB2-Retro**,EB3-I**,EB2-I**,Waiting2File**
2007*,28087,14002,14085,8109,15752,15752,15846,158 46,9123,9123,65690
2008,49205,22870,26335,16568,25729,25729,29627,296 27,18639,18639,122261

2010,70237,30644,39593,28930,34475,34475,44542,445 42,32546,32546,188651

Again these are numbers based on the date of PERM approval and not PERM filing. So the actual demand may shift. For example, 2010 saw large number of PERM approvals but they all were not filed in 2010.
again 2010 means Oct 2009 to Sept 2010 and so on.
Furthermore recollect what happened with family-based quota: USCIS moved the dates too slow for a number of years and many thousand visas were wasted. So Ombudsman reprimands. Then USCIS moves them too fast, there is a deluge of applications and now they retrogress two years. I would be very surprised if something different happened with employment-based applications.
Oh to pity our fate at the hands of USCIS!
