The purpose of the series is to document the national practices used in the collection of various types of labour statistics in order to assist users in assessing their suitability for particular needs, as well as evaluating their quality and comparability. The methodological descriptions can consequently be seen as companions to the ILO Year Book of Labour Statistics, the Bulletin of Labour Statistics and the ILO's statistical Web site, http://laborsta.ilo.org.

The descriptions in this section provide methodological information on national statistics of strikes and lockouts. Information about new developments and corrections received in the ILO are introduced regularly in the data base.

The descriptions are produced by the ILO Department of Statistics.
