GlobalTestMarket has a very active survey division and requires participants worldwide over the age of 14. The views of those under 14 may be sought but the invitation will go to the parent for the child to complete.

You earn "marketpoints" each time you respond to a survey request - the closer you fit the demographics for the survey, the higher the points earned but you'll usually earn 5 points even if you don't qualify at all. A typical survey of up to 20 minutes to complete will earn 50 to 100 MarketPoints. You can also earn extra points when you refer others. Each point is worth $0.05 and you need 1000 points to qualify for payment by cheque.

They seem to be fairly active. I'm receiving at least 2 or 3 surveys every week at present. For full details and registration form, visit GlobalTestMarket

Whenever you've accumulated more than 1000 points, you can request a check for cash.
