Why does our generation less religious?

I was thinking about it the other day, and I was considering that my generation Y is less relgious than the prvious people.
When going to a christian church, you do not see a lot of young people besides children with their parents. You see a lot of elderly people. That is because it is how they were raised, now we are very simple with things.
We feel like we do not have enough time for religion.
What do you think? Are we less religious than our older generations?

Thanks.
