Methods and apparatus to correlate census measurement data with panel data

An apparatus comprising:

• a beacon handler to access a message sent from a requesting device in response to accessing media that includes a tag causing the requesting device accessing the media to send the message to the beacon handler with an identification of a geographic location of the requesting device and media identifying information;
• a location handler to identify locations of a plurality of panelist homes;
• the location handler to compare the geographic location of the requesting device with the locations of the plurality of panelist homes;
• a comparator to determine whether the geographic location of the requesting device is within a threshold distance of a first location of a first one of the plurality of panelist homes;
• and
• a panelist associator to identify a user of the requesting device as a panelist residing at the first one of the panelist homes and associate the media identifying information to panelist data associated with the first one of the panelist homes when an output of the comparator to indicate the geographic location of the requesting device is within the threshold distance of the first location of the first one of the plurality of panelist homes.
