How evaluate astro data for vocational indicators?

Hi I have the birthdates of about 100 computer programmers

Whats the best way to analyze the data to come up with similarities in their charts??

I cant post the URL because I dont have enough posts

I decided to do aspects first, these are game programmers not business software programmers so there maybe some artistic indicators in there

Something common was venus trine or conjunct neptune
also venus square or opposite uranus
Jupiter trine or conjunct sun

Ive only done about 40 so I still have another 70 to go

These are only the people who participate in the forums, so maybe the jupiter - sun thing is more indicative of someone who would join and participate in forums?
