Methods and apparatus to compensate for server-generated errors in database proprietor impression data due to misattribution and/or non-coverage

A non-transitory computer-readable medium comprising instructions that, when executed, cause an audience measurement computing system to perform operations comprising:

• receiving, via a network interface of the audience measurement computing system and via a first network connection with media devices located at a plurality of households, first network communications indicative of impressions of media;
• receiving, from a database proprietor server located remotely from the audience measurement computing system, and via the network interface and a second network connection with the database proprietor server, second network communications indicative of demographic information associated with the impressions;
• based on the first network communications and the second network communications, logging, in a database, impression data comprising the impressions and the associated demographic information, wherein the impression data comprises a computer-based impression count error for a media device, wherein the computer-based impression count error is an error in which a first member and a second member of a household simultaneously viewed a presentation of the media by a media device of the household, but the audience measurement computing system only logged one impression corresponding to that presentation of the media in the database, wherein the impression is attributed to a first demographic group of the first member;
• determining a co-viewing probability that the first member and the second member simultaneously viewed the presentation of the media;
• and
• based on the co-viewing probability, correcting the computer-based impression count error in the impression data for the household by logging, in the database, an additional impression of the media, attributed to a second demographic group of the second member of the household, wherein the determining and correcting are performed without using panelist metering software installed on the media devices located at the plurality of households that collects data about media access by respective members of the plurality of households and without communicating with the media devices to obtain the data about the media access, thereby reducing usage of computational resources at the media devices and conserving network bandwidth of the audience measurement computing system.

A method performed by an audience measurement computing system, the audience measurement computing system comprising a network interface, a processor, and memory, the method comprising:

• receiving, via the network interface and a first network connection with media devices located at a plurality of households, first network communications indicative of impressions of media;
• receiving, from a database proprietor server located remotely from the audience measurement computing system, and via the network interface and a second network connection with the database proprietor server, second network communications indicative of demographic information associated with the impressions;
• based on the first network communications and the second network communications, logging, in a database, impression data comprising the impressions and the associated demographic information, wherein the impression data comprises a computer-based impression count error for a media device, wherein the computer-based impression count error is an error in which a first member and a second member of a household simultaneously viewed a presentation of the media by a media device of the household, but the audience measurement computing system only logged one impression corresponding to that presentation of the media in the database, wherein the impression is attributed to a first demographic group of the first member;
• determining a co-viewing probability that the first member and the second member simultaneously viewed the presentation of the media;
• and
• based on the co-viewing probability, correcting the computer-based impression count error in the impression data for the household by logging, in the database, an additional impression of the media, attributed to a second demographic group of the second member of the household, wherein the determining and correcting are performed without using panelist metering software installed on the media devices located at the plurality of households that collects data about media access by respective members of the plurality of households and without communicating with the media devices to obtain the data about the media access, thereby reducing usage of computational resources at the media devices and conserving network bandwidth of the audience measurement computing system.
