what is the most common way that singles meet each other today?

I think a few places that are in the top ten would be: online, bars/clubs, work place, through friends/family. I have been out of the dating loop for awhile so I am not sure if it's current.

I think younger singles tend to meet most commonly in school or college, either in classes or through related social events. For older singles (and by older I'm thinking mid-20's and above) I think the most common ways to meet are through mutual friends and family, through work-related activities, and online. Of course, I know of many people who are meeting and dating through other means too. Through church, meeting in bars or clubs, and meeting others while on vacation are just a few.

Usually through common friends and in organizations i joined with.
