OzTAM, Regional TAM and Nielsen have designed a database to represent the Australian population, a ‘Virtual Australia’.

The Television Audience Measurement (TAM) Service uses a robust and large-scale Establishment Survey that collects data from 65,000+ interviews each year about respondents’ homes, TV viewing technologies and the demographics of their household members. In combination with Australian Bureau of Statistics official population data, the VOZ database is constructed to contain approximately 27 million synthesised ‘individuals’ to represent the profile of all Australians.
