Abstract: A group of households associated with known content viewing behavior may be determined. The group of households may be compared to at least one household with unknown content viewing behavior, based on a plurality of characteristics. Based on the comparison, a subset of the group of households that is associated with characteristics most similar to characteristics associated with the at least one household with unknown viewing behavior may be determined. A predicted content viewing behavior associated with the at least one household with unknown content viewing behavior may be determined based on the known content viewing behavior of the subset of the group of households.

Abstract: Systems, methods, and devices relating to determining viewership data are described herein. In a method, viewing data associated with a household is received. A first portion of the viewing data is indicative of video programming associated with a first video device and a second portion of the viewing data is indicative of video programming associated with a second video device. One or more characteristics associated with the first and second portions of the viewing data are determined. Based on the one or more characteristics and a comparison of the respective video programming associated with the first and second video devices, it is determined that the first portion of the viewing data is duplicative, at least in part, with the second portion of the viewing data.
