Methods and apparatus for audience and impression deduplication

At least one non-transitory computer readable medium comprising instructions that, when executed, cause at least one processor to at least:

• determine a subunion of at least first and second marginal audiences of media based on panel data and census data, the panel data including a panel impression count and a panel audience size, and the census data including a census impression count;
• determine a census audience size of the at least the first and second marginal audiences based on the panel impression count and the panel audience size;
• determine a subunion census audience size based on the census audience size, the subunion census audience size corresponding to an overlap between the at least the first and second marginal audiences;
• and
• generate a report including the census audience size and the subunion census audience size, the census audience size indicative of audience members represented in the census data that accessed the media, and the subunion census audience size indicative of audience members represented in the census data of the subunion of the at least the first and second marginal audiences that accessed the media.
