Switch in Category of Facebook Data Used

During recent review of our estimates, we found that daily values gathered from Facebook have been unstable. As a result, there have been day-to-day fluctuations for some countries in the online model estimates. We have switched the category of Facebook data we are using to Monthly Active Users (MAUs) as these are more stable than Daily Active Users (DAUs). The data for all previous reports have been revised to reflect this change.
