How to relate the census measurement data and panel data and equipment

摘要

Methods, apparatus, and systems are disclosed to correlate census measurement data with panel data. An example method includes accessing a message sent from a requesting device in response to accessing media that includes a tag causing the requesting device to send the message to a monitoring entity with an identification of a geographic location of the requesting device and media identifying information. The example method also includes determining locations of a plurality of panelist homes and comparing the geographic location of the requesting device with the locations of the panelist homes. When the geographic location of the requesting device is within a threshold distance of a first one of the panelist homes, identifying a user of the requesting device as a panelist residing at the first panelist home, and associating the media identifying information with panelist data associated with the first one of the panelist homes.
