Free mobile app analytics & demographics from Quantcast

How does this differ from what Flurry provides?
Quantcast is a direct measurement provider for more accurate mobile app demographics and provides six categories of demographic segments: Household composition, Income, ethnicity and education, while Flurry has only age, gender and interests.
Seems like flurry only gives age and gender data: http://www.flurry.com/flurry analytics.html#insight
Very cool!
