"And even big tech companies have pretty even gender ratios"

Thats very false. Here is a sample of companies and their ratio:

Google: Median Age 29 years Gender Male 65% Female 35%

Yahoo:

Median Age 32 years Gender Male 66% Female 34%

Facebook:

Median Age 27 years Gender Male 68% Female 32%

Sun:

Median Age 37 years Gender Male 74% Female 26%

eBay:

Median Age 32 years Gender Male 62% Female 38%

Non Tech:

UC Berkeley (employees):

Median Age 29 years Gender Male 51% Female 49%

City of San Francisco:

Median Age 32 years Gender Male 62% Female 38%

I work in one of these companies and Im surprised to see this. But then again Im an engineer. These numbers are bloated by the HR/customer service/sales people I guess. If you are a tech in tech company,the split is like 90-10.

I also work in one of these and I'm not terribly surprised, but my own observations are that it's a bit less lopsided than that. I already mentioned that both my team and my cube are split 3-4, so 42% female. The other team I work with is 6 females and 9 males, so 40% female. That's in engineering - UI design and UX research seem to be even more balanced, and HR of course is virtually all female. At a rough guess, the numbers I see in the cafes are maybe 60-40 male/female.

Agreed. A company is a miniature snapshot of the city it's in. If the girls in marketing in HR aren't into engineers in general (or vice versa) it doesn't matter that they work in the same building.

You can search for companies profile in linked in. (I actually I friends that work there, and they complain the same, no women).

Linkedin. Median Age 33 years Gender Male 70% Female 30%

Ps. While that counts only people that have a linkedIn profile, I would remind you Facebook has more women that guys, so I would assume that women are very familiar with social networks, and not afraid of them.

I'd think women would be way over represented in that, at least, when I was at Google, it was the recruiters and HR people flocking to LinkedIn, not the engineers. FWIW, I was on four teams at Google. I was the only woman on all of them except for Orkut, which was about half women.

As a personal anecdote, the m/f ratio in a company (one of the biggest ISPs in my country) a friend worked was supposed to be 67-33, according to LinkedIn. When I told him that, he said that certainly it wasn't the case. He worked in their HQs, along with as much as 90% of their employees, and one of the first things that made an impression on him was that women were so much more than men. By the way, there are profiles of 183 employees of that company in LinkedIn, with the error margin not sufficient to explain the discrepancy.

So, you are concluding that linked-in is more popular amongst men.
