Look around your office. Do you see anyone over 40? No? Yes. A couple people on my team now, most of management (including our immediate supervisor, who just recently moved up from being a normal team member), whoever's in the cubes I saw those black "40" balloons on, the people who first built some of the corporate systems (well, the ones who haven't retired yet), etc. Tech is a growing field. How big was it in 1995, compared to today? That's a decent approximation of what ratio of over 40 / under 40 you'd expect, assuming career changes aren't common enough to mess up the numbers too badly.
