Methods and apparatus to correlate a demographic segment with a fixed device

An apparatus comprising:

• a monitoring instructor to:
• transmit, to a manufacturer of a fixed device, first instructions, which, when executed, cause the fixed device to report a record indicating a first Internet Protocol (IP) address used by the fixed device to a server;
• and
• transmit, to a media provider, second instructions, which, when executed, cause a mobile device to transmit a monitoring data record to the server, the monitoring data record including a second IP address used by the mobile device;
• a demographic segment estimator to estimate a demographic segment of a user of the mobile device;
• and
• a probability estimator to:
• determine a baseline probability that the user was present at the fixed device during a time segment based on the demographic segment;
• in response to determining the first IP address matches the second IP address during the time segment, increase the baseline probability to reflect a stronger likelihood the user was present at the fixed device during the time segment;
• and
• in response to determining the first IP address does not match the second IP address during the time segment, negatively bias the baseline probability to reflect a weaker likelihood that the user was present at the fixed device during the time segment.

An apparatus comprising:

• at least one memory;
• instructions;
• and
• at least one processor to execute the instructions to at least:
• transmit, to a manufacturer of a fixed device, first instructions, which, when executed, cause the fixed device to report a record indicating a first Internet Protocol (IP) address used by the fixed device to a server;
• and
• transmit, to a media provider, second instructions, which, when executed, cause a mobile device to transmit a monitoring data record to the server, the monitoring data record including a second IP address used by the mobile device;
• estimate a demographic segment of a user of the mobile device;
• and
• determine a baseline probability that the user was present at the fixed device during a time segment based on the demographic segment;
• in response to determining the first IP address matches the second IP address during the time segment, increase the baseline probability to reflect a stronger likelihood the user was present at the fixed device during the time segment;
• and
• in response to determining the first IP address does not match the second IP address during the time segment, negatively bias the baseline probability to reflect a weaker likelihood that the user was present at the fixed device during the time segment.

A non-transitory computer readable medium comprising first instructions, which when executed, cause a processor to at least:

• transmit, to a manufacturer of a fixed device, second instructions, which when executed, cause the fixed device to report a record indicating a first Internet Protocol (IP) address used by the fixed device to a server;
• and
• transmit, to a media provider, third instructions, which when executed, cause a mobile device to transmit a monitoring data record to the server, the monitoring data record including a second IP address used by the mobile device;
• estimate a demographic segment of a user of the mobile device;
• determine a baseline probability that the user was present at the fixed device during a time segment based on the demographic segment;
• in response to determining the first IP address matches the second IP address during the time segment, increase the baseline probability to reflect a stronger likelihood the user was present at the fixed device during the time segment;
• and
• in response to determining the first IP address does not match the second IP address during the time segment, negatively bias the baseline probability to reflect a weaker likelihood that the user was present at the fixed device during the time segment.
