System and method for associating individual household members with television programs viewed

A method executes at a server system with one or more processors and memory. The server receives demographic information for a plurality of household members. The demographic information includes at least age and gender. The server receives web activity information for the household. The server identifies one or more web activity sessions from the web activity information and selects one of the web activity sessions. The server identifies one or more web sites visited during the selected web activity session and accesses demographic skew data for at least a subset of the web sites visited. The demographic skew data for a web site identifies fractions of visitors to the web site from predefined demographic segments. The server associates a household member with the web activity session at least in part by correlating the demographic skew data of the web sites visited with the demographic information of the first household member.
