FIRST MONTH OF SELECTION IN SURVEY

This identifier is an unique ID number for the first month that someone was selected to participate in the Labour Force Survey (LFS).

It has the same format as Survey month ID [ABSMID], where the last 2 digits relate to the calendar month and the leading digit or digits relate to the year.

Each person from a private dwelling has only one First month of selection in survey and it is the same for all records of data.

The First month of selection in survey may not necessarily be the same month as the first record of data, as the respondent may not have been available in the first month of selection, or the dwelling may have been vacant. This is revealed when comparing this identifier to Survey month ID.

Refer to Longitudinal structure for more information.

People in special dwellings (see Residence Status [URSTATC]) only have one record of data, and the First month of selection in survey is the same as the Survey month ID (i.e. the month that the data was collected). This is regardless of whether the actual dwelling itself was selected in prior months, as data collected from special dwellings are assembled as cross-sectional ('point-in-time') measurements at the Person level rather than the Household/Dwelling level (see Household ID [ABSHID]).
