determine a first census-level audience size based on the first one of the plurality of cross-demographic total census parameter values; determine a first census-level impression count based on the first one of the plurality of cross demographic total census parameter values; determine whether the first one of the plurality of cross-demographic total census parameter values satisfies a constraint based on the first census-level impression count; when the constraint is not satisfied: (a) discard the first one of the cross-demographic total census parameter values, and (b) select a second one of the cross-demographic total census parameter values, the second one of the cross-demographic total census parameter values to determine a second census-level audience size and a second census-level impression count to satisfy the constraint; and when the constraint is satisfied: store the first census-level audience size and the first census-level impression count in computer memory, and send the first census-level audience size and the first census-level impression count to a network-connected device. ### Claim 9 (depends on 8) The at least one non-transitory computer readable medium of claim 8, wherein the instructions, when executed, cause the at least one processor to determine the first census-level impression count further based on the first census-level audience size. ### Claim 10 (depends on 8) The at least one non-transitory computer readable medium of claim 8, wherein the first census-level audience size and the first census-level impression count correspond to at least one of a webpage, an advertisement, or video. ### Claim 11 (depends on 8) The at least one non-transitory computer readable medium of claim 8, wherein the instructions, when executed, cause the at least one processor to select the first and second ones of the cross-demographic total census parameter values from a range, an upper bound constraint of the range being a peak cross-demographic total census parameter value. ### Claim 12 (depends on 8) The at least one non-transitory computer readable medium of claim 8, wherein the third-party audience size and the third-party impression count are based on impressions of media, the impressions attributable to subscribers of a database proprietor. ### Claim 13 (depends on 8) The at least one non-transitory computer readable medium of claim 8, wherein the first census-level impression count corresponds to a first demographic, and the instructions, when executed, cause the at least one processor to determine that the first one of the plurality of cross-demographic total census parameter values satisfies the constraint when a sum of the first census-level impression count and second census-level impression counts corresponding to second demographics equal a census-level total impression count. ### Claim 14 (depends on 13) The at least one non-transitory computer readable medium of claim 13, wherein the census-level total impression count is based on first impressions of media logged by an audience measurement entity, the audience measurement entity separate from a database proprietor that generates the third-party audience size and the third-party impression count based on second impressions of the media, the second impressions attributable to subscribers of the database proprietor. ### Claim 15 A method to determine census-based audience metrics of media across multiple demographics, the method comprising: determining, by executing an instruction with a processor, a first one of a plurality of cross-demographic total census parameter values based on a ratio of a third-party impression count and a third-party audience size; determining, by executing an instruction with the processor, a first census-level audience size based on the first one of the plurality of cross-demographic total census parameter values; determining, by executing an instruction with the processor, a first census-level impression count based on the first one of the plurality of cross demographic total census parameter values; determining, by executing an instruction with the processor, whether the first one of the plurality of cross-demographic total census parameter values satisfies a constraint based on the first census-level impression count; when the constraint is not satisfied: (a) discarding, by executing an instruction with the processor, the first one of the cross-demographic total census parameter values, and (b) selecting, by executing an instruction with the processor, a second one of the cross-demographic total census parameter values, the second one of the cross-demographic total census parameter values to determine a second census-level audience size and a second census-level impression count to satisfy the constraint; and when the constraint is satisfied: storing, by executing an instruction with the processor, the first census-level audience size and the first census-level impression count in computer memory, and sending, by executing an instruction with the processor, the first census-level audience size and the first census-level impression count to a network-connected device. ### Claim 16 (depends on 15) The method of claim 15, wherein the first census-level impression count is determined based on the first census-level audience size. ### Claim 17 (depends on 15) The method of claim 15, further including selecting the first and second ones of the cross-demographic total census parameter values from a range, an upper bound constraint of the range being a peak cross-demographic total census parameter value. ### Claim 18 (depends on 15) The method of claim 15, wherein the third-party audience size and the third-party impression count are based on impressions of the media, the impressions attributable to subscribers of a database proprietor. ### Claim 19 (depends on 15) The method of claim 15, wherein the first census-level impression count corresponds to a first demographic, and further including determining that the first one of the plurality of cross-demographic total census parameter values satisfies the constraint when a sum of the first census-level impression count and second census-level impression counts corresponding to second demographics equal a census-level total impression count. ### Claim 20 (depends on 19) The method of claim 19, wherein the census-level total impression count is based on first impressions of the media logged by an audience measurement entity, the audience measurement entity separate from a database proprietor that generates the third-party audience size and the third-party impression count based on second impressions of the media, the second impressions attributable to subscribers of the database proprietor.
