Specialist products

Microdata are small samples of data for whole households and individuals.

Microdata products include some associated census characteristics but no information that could identify a household or individual.

Microdata products enable researchers to look at combinations of characteristics that are not generally available from the standard census tables, and to perform different types of analyses not possible from standard tabulations.
