OVERVIEW

The Australian Census and Migrants Integrated Dataset (ACMID), 2011 TableBuilder product is single-level file that counts persons and has data items as collected at the 2011 Census of Population and Housing.

The ACMID, 2011 TableBuilder contains linked data from the 2011 Census of Population and Housing and from the Department of Immigration and Border Protection's (DIBP) Settlement Database (SDB). Census data items include; age, sex, relationship in household, geographic area (place of usual residence, place of enumeration, place of work), country of birth, birthplace of male/female parent, Australian citizenship, proficiency in spoken English, religious affiliation, year of arrival, ancestry, language spoken at home, labour force status, level of education attainment, non-school qualifications, voluntary work etc. The SDB data items relating to a person's migration event include:

• VISAP: Visa class of a person's entry into Australia
• VLOCP: The location of where a person's visa was granted i.e. onshore or offshore
• VPAFP : A person's applicant status i.e. main applicant or secondary.

The data items included in the ACMID, 2011 TableBuilder are grouped under broad headings and subheadings. A complete data item list can be accessed from the Downloads page.


MULTI-RESPONSE FIELDS

Only one Census data item, Ancestry, allowed respondents to provide one or two responses. Each response category for a 'multi-response question' (or data item) is treated as a separate data item.

The Ancestry variable allows respondents to report up to two ancestries on their Census form. Respondents do not have the option of ranking their answers to the ancestry question, so where a respondent reports two ancestries, those two ancestries have equal standing. The basis for allocating ancestries to the variables ANC1P and ANC2P is administrative only and is determined by the order in which they are processed.

An example of differences in counts of responses for ANCP 1 and ANCP 2 can be found in section Using the Dataset in TableBuilder.

It should be noted that the sum of individual multi-response categories can be greater than the population or number of people applicable to the particular data item as respondents are able to select more than one response.
NOT APPLICABLE CATEGORIES

Most data items included in the microdata include a 'Not applicable' category. The classification value of the 'Not applicable' category, where relevant, are shown in the data item lists in the Downloads tab.
