Methods and apparatus to generate corrected online audience measurement data are disclosed. An example apparatus includes programmable circuitry to at least receive, from a server of a database proprietor, a first audience count, a second audience count, and a third audience count, the first audience count indicative of a first number of impressions corresponding to first network communications, the second network communications from second computing devices, and the third audience count indicative of a third number of impressions corresponding to ones of the first network communications and ones of the second network communications attributed to the first media category and the second media category accessed by the first demographic group, the first audience count including a server-generated duplicated audience count generated by the server of the database proprietor, and calculate a deduplication factor for the first demographic group using the first, second, and third audience counts.

Methods and apparatus to generate corrected online audience measurement data

Methods and apparatus to generate corrected online audience measurement data are disclosed. An example apparatus includes an impressions collector to receive a first audience count indicative of first impressions attributed to a first media category for a demographic group, a second audience count indicative of second impressions attributed to a second media category accessed by the demographic group, and a third audience count indicative of third impressions attributed to the first media category and the second media category accessed by the demographic group, the first audience count including a duplicated audience count; a factor generator to calculate a deduplication factor using the first audience count, the second audience count, and the third audience count; an audience calculator to determine a corrected audience count of the first media category to correct the duplicated audience count; and a ratings data generator to generate ratings information for the first media category.

Methods and apparatus to generate corrected online audience measurement data are disclosed. An example method includes determining a corrected audience count of streaming media for a demographic group by: calculating a deduplication factor for a demographic group using a first audience count, a second audience count, and a third audience count; estimating a fourth audience count for the demographic group, the fourth audience count indicative of a number of people who accessed the streaming media; estimating a fifth audience count for the demographic group, the fifth audience count indicative of a number of people who accessed text content; and applying the deduplication factor to a sum of the fourth audience count and the fifth audience count to determine the corrected audience count. The example method also includes generating ratings information for the streaming media based on subtracting the corrected audience count from the first audience count.
