The longest wage index series with 1939 as the base year
From 1942 to 1994, wage growth was calculated on the basis of data from the October survey on wages and pay. From 1994, the wage index has been calculated using a new baseline. The Ordinance on the Conduct of Federal Statistical Surveys of 30 June 1993 (status of 13 July 2004) stipulates that wage growth is now based on accident statements by the Central Office for Statistics in Accident Insurance (SSUV). Thanks to the entry into force on 1 January 1984 of the Federal Act on Accident Insurances (LAA) which obliges all employees to be insured, the statistic can cover all of these persons.
Wage growth by sex
The more sustained increase in the women's nominal wage index continues a long-term trend observed since the middle of the 1960s. However, the higher level of growth of women's wages is relative. This higher growth can partly be explained by the calculation of variation. The fact that women's wages are globally lower than those of men partly explains why growth variation in women’s wages in % is higher in the long term.
