1. An audience measurement system for correcting age-based misattribution errors, the audience measurement system comprising:
a processor; and
a non-transitory computer-readable storage medium, having stored thereon program instructions that, upon execution by the processor, cause performance of a set of operations comprising:
receiving, from a database proprietor, anonymized subscriber demographic data of a plurality of subscribers registered with the database proprietor, wherein the anonymized subscriber demographic data comprises corresponding age characteristics of the plurality of subscribers and is based on network communications received by the database proprietor from client devices of the plurality of subscribers;
storing, in a database, the anonymized subscriber demographic data;
receiving, from a client device, impression data after a media item is accessed on the client device, wherein the impression data comprises an impression request and a user identifier;
generating a demographic impression of a plurality of demographic impressions by attributing anonymized subscriber demographic data of a subscriber of the plurality of subscribers to the impression data,
wherein the demographic impression comprises an impression date and the user identifier, and
wherein the impression date and the user identifier are matched to the anonymized subscriber demographic data of the subscriber of the plurality of subscribers;
retrieving, based on the user identifier, a predicted age probability density function,
wherein the predicted age probability density function defines, for each of a plurality of age ranges, a respective probability that an actual age of the subscriber is within that age range;
updating the predicted age probability density function to generate an age-corrected probability density function; and
using the age-corrected probability density function to update the demographic impression to correct the age characteristic of the subscriber; and
outputting, using the updated demographic impression, media ratings information about the media item, wherein the updated demographic impression comprises a corrected age characteristic of the subscriber.
