The Virtual Australia (VOZ) service Total TV universe estimates (UEs) provide the number of people in each market across Australia, categorised by age group and gender and include people in zero TV homes. These estimates are projected for the upcoming year using the trended official Australian Bureau of Statistics (ABS) estimates of the resident population. OzTAM and Regional TAM’s large scale rolling Establishment Survey serves as a crucial source of additional population characteristics including details about people, their households, and relevant in-home technologies.
