(Source: study on 2800 phone users that played Pokemon GO. Data collected for at least 4 weeks having the first gaming session in the middle. Data was collected through an app that monitors your phone usage, no self-reported data. Will be presented at MobileHCI '17)

Initial sample size was 21k users but we've reduced it to the people that filled some questionnaire regarding demographics and personality traits. To which parameters are you referring?
