METHODS AND APPARATUS TO GENERATE AUDIENCE METRICS

Methods, apparatus, systems, and articles of manufacture are disclosed to generate audience metrics. An example apparatus includes online panel factor generator circuitry to generate an online panel adjustment factor based on television panel data and online panel data; over-the-top (OTT) factor generator circuitry to generate an OTT adjustment factor based on the television panel data and a portion of the online panel data, the portion of the online panel data corresponding to OTT panel data; independence probability factor generator circuitry to generate an independence probability adjustment factor; and a convergence circuitry to: generate an aggregated adjustment factor based on the online panel adjustment factor, the OTT adjustment factor, and the independence probability adjustment factor; and generate a deduplicated reach corresponding to a media item based on a comparison of the aggregated adjustment factor to historical data.
