I'm looking for demographic data for mobile games.
I've looked at App Annie, SensorTower, and Apptrace. These three sources give estimates on the app store ratings, number of downloads, and rankings in each country -- but their free versions provide no information as to WHO is using these apps/games. I want to get a better idea of WHO the users are.
Data - I'm looking for information regarding players' age, sex, ethnicity, income, race, and basically anything that could assist in targeting mobile users in a more precise manner. Monetization is key. My clients, of course, are interested in targeting users who are spending money.
Region - English speaking markets (primarily North America and Western Europe)
Any format or source is acceptable. I'm looking for any kind of data regarding mobile gaming in English markets -- and I will, of course, try to assess the credibility on my own. Essentially, I'm looking for free and open estimates/analytics -- as signing up for a subscription based service is pricy for a small business.
