Description of Datafiles 1971 through 2001

1. 1971 through 2001 Austria is providing 4 files for the following Population Census': 1971 1981 1991 2001 There are no existing data files for further counts.

2. Unified Layout The characteristics have a 3-place/part code. This gives the possibility for a characteristic to have more codes. The basis for this is:

 Gross or generalized (for example age in 1-year and 5-year cohorts)  Different definitions (for example Occupation 1 and Occupation 2)  Different classifications (for example ISCO and a national classification system)

The full characteristic structure is not provided for all counts. A unified structure is provided. In other words, the location of a characteristic is the same in each of the four files. If a characteristic does not occur in a specific count, the position is blank. This is explained in the comments for the specified count. (Some positions are blank in all counts. This occurs when the contents could not be determined technically [requires hand edit].)

3. Line description and commentary The files have the following descriptions provided:

3.1 Line description The location of each characteristic in the file

3.2 Characteristic comments All characteristics are listed in an EXCEL spreadsheet and include the following information: 1. Characteristic code 2. Official name of the characteristic 3. Exact description of the characteristic 4. Identification of the counts containing the characteristic 5. The respondent group (universe) 6. Technical/organizational instructions for constructing the characteristic 7. Additional information: definition (such as from the ECE recommendations), comments on the class.

When the space is not sufficient, the text has been written in a second sheet "Annex" in the EXCEL file. 4.
