Methods, systems, and apparatus, including computer programs encoded on computer storage media, for determining geo-locations of users from user activities. One of the methods includes obtaining information associated with multiple client devices located at multiple geographic locations; identifying a group of client devices based on network addresses assigned to the client devices; obtaining a prediction that the client devices are in a first geographic location; and determining a probability distribution that the client devices are distributed across multiple locations including or adjacent to the first geographic location. |
