We knew it wouldn’t be long before Do-No-Evil became Try-Not-To-Do-Much-Evil, but that day came and went a loooong time ago. Google buying YouTube wasn’t even that big of a deal, and now it’s just “how things are.” Though now… perhaps we were a bit hasty letting everything go unmentioned. YouTube will now show you demographic stats for videos you’ve posted, the feature was rolled out as a new part of YouTube Insights, which appeared in March.

For now, you get a bar chart representing the percentage of your audience in different age groups, and a pie chart showing the breakdown of gender. You can then filter that data by country or for a specific time frame. Additionally, YouTube has rolled out aggregate data, so you can see the combined demographics for all of your videos. The data is all anonymous.
