Years.

For demographic data, the reference period is the calendar year.

The EU-LFS is designed as a continuous quarterly survey with interviews spread uniformly over all weeks of a quarter.  The reference week starts on Monday and ends on Sunday. From 2004, in all countries providing quarterly data, the quarterly sample is spread uniformly over all weeks of the quarter. The reference quarter is the calendar quarter except for Ireland and the United Kingdom (until 2006), which use the seasonal quarter (Dec-Feb, Mar-May, Jun-Aug, Sep-Nov). Annual results are calculated averaging quarterly data.

Estimates are calculated twice a year. The estimates for year Y are first released in summer of year Y+1. The data available at that time are the LFS data for year Y and the life tables for year Y-1. The calculation uses the life tables for Y-1 as a provisional proxy for the life tables for year Y. These estimates are revised six months later, at that time both the LFS data and life tables for year Y are available.

Not estimated.
