What is the CDMF?

The Collection District Master File contains basic counts and associated geographic codes for every Collection District (CD) in Australia. This information allows simpler aggregation to higher level geographic areas and facilitates comparisons with previous census data.

The record for each CD includes geographic area codes for State, Census Division, Census Subdivision, 1981 CD, LGA Section, Commonwealth Electoral Division, State Electoral Division, Statistical Division, Statistical Subdivision (District), Locality, Section of State, State Area, State Suburb, Postcode, 1976 LGA, 1981 LGA, 1976 CD indicative, 1971 CD indicative, CD Serial Number, Confidential CD, Study Area, Latitude, Longitude, and Area in hectares. These are used both in their own right and to produce higher level aggregates for the population and dwelling data: counts for males, females and total persons, and occupied, unoccupied and total dwellings. The record also contains comparability indicators to the 1971 and 1976 Census CDs.

There are 26,759 logical records, each of 128 characters in length, containing 31 cells of CD information.

For some basic information about the way Census 81 was planned, designed, executed and processed, information on the person and dwelling characteristics included in statistical output and some guidance to other census products, see "Making Sense of Census 81".
