Virtual Worlds consultants and analysts KZero recently pumped out two mid-summer virtual world statistics that should get you to sit up and pay attention. They’ve provided not only a breakdown of where people are headed, but what age groups are predominant in these virtual worlds.

Admittedly, the first set up stats is slightly complex at first glance, but upon further inspection, these charts are nothing short of eye opening.

This chart visualizes ages breakdowns and the associated virtual worlds that these ages are taking part in, along with each individual world’s launch data and timeline.

If pretty circular chats with fancy blue and red dots don’t really do it for you, KZero has gone the extra mile and broken things down even more. According to their research, the Q2 2009 virtual worlds sector inhabitant count now stands at 579 million. This number represents a 38.6 percent increase over Q1, where inhabitant totals stood at 417 million.

Taking data-points of the average age of users within each world, and then allocating this data to all accounts, KZero affirms that predominant age in these worlds is 14. The majority of these VW inhabitants come from big players including Weeworld, Habbo, and Stardoll.

Having a different look at the same data, the graph below represents cumulative registered accounts by age.

There’s obviously a plethora of activity in the 5-14 age group, a moderate increase from 15-20, but after that, a relatively flat curve. For the purposes of this study, Second Life was excluded.

As KZero points out, the majority of activity, and associated monetization scramble, is happening in the 10-15 year old age group. Totaling 334 million registered accounts, over 57 percent of the entire segment, this age segment represents the largest potential for growth. Holding 19 percent of the entire segment is the 5-10 year old age group. Clearly, youth oriented virtual worlds such as CampFu are smack dab right in the middle of the majority of virtual worlds citizens’ radar.
