Great catch.
Here's their statistics on graduation rates by degree. It's a few years old but the latest isn't going to be all that different.
http://sitemaker.umich.edu/obpinfo/files/umaa_degrsbystudyfi...
Aerospace engineering - 102
Biomedical engineering - 48
Chemical engineering - 68
Civil Engineering - 50
Earth Systems Engineering - 1
Engineering - 9
Engineering Physics - 10
Financial Engineering - 16
Nuclear Engineering - 16
Now I'm going to guess none of the above degrees are the majors we are talking about for these startups, who are looking for software developers.
More relevant:
Computer Engineering - 84
Computer Science - 158
Electrical Engineering - 170
---
Total: 412
Maybe we should throw in all the Math, Physics, Linguistics and Music majors as well? Those are fields that are often sorted through for developers. It's a small number of each that goes into programming, but not insignificant.
In any case, this is Ann Arbor only. Can the claim of 8000 engineering graduates per year be substantiated for the entire system. Seems unlikely, but we need more data, and we'd definitely have to be including every field that has any possible connection, perhaps someone had a statistic that said there were 7002 STEM degrees granted system wide per year, and that turned into "around 8000" and then "8000"?
Ah, here is a year by year summary and one that puts all forms of engineering in one category:
http://sitemaker.umich.edu/obpinfo/files/umaa_degrssummary_1...
year - # eng degrees
2006 - 1034
2007 - 1065
2008 - 1150
2009 - 1198
2010 - 1254
That is undergraduate ONLY. There are also on that list comparable numbers of graduate degrees, so double the number for all degrees altogether: 1254 + 1035 = 2289 engineering degrees conferred in 2010. It's kind of amazing that they have the same number of grad students as undergrad, that means there is a near 1:1 ratio between grad students and undergrad, so each undergrad theoretically could be taught privately by a single grad student tutor if they wanted.
So to hit 8000 we need only 3 other U. Michigan campuses the same size as Ann Arbor.
