The labour cost index measures the quarterly change in average labour costs per hour worked. The statistics cover almost the whole private sector as well as the central government and local government sectors. Excluded from the statistics are agriculture, forestry and fishing. Within the local government sector, data on education are not so far included in the statistics. In addition to the actual labour cost index, the labour cost index includes three complementing indices: the index of wage costs, the index of social costs and the labour cost index without one-off and extraordinary cost components.
