Time series and chain-linking

Time series

Price trends have been monitored and measured in Austria since the 18th century. A weighting scheme was first calculated in 1912 in conjunction with a consumer survey among employee households in Vienna.

The Retail Trade Price Index 1938 (RPI) was actually only calculated from the year 1948 onwards and continued until February 1959. The weightings were based on the expenditure of a working-class family of four in Vienna. The consumer basket was divided into nine main groups. After that new CPI series were compiled in 1966, 1976, 1986, 1996, 2000, 2005 and 2010 each based on a Household Budget Survey conducted in the year t-1. With the publication of the CPI 2015 thirteen different index series based on the national concept are available. For the CPI 2015 a revised basket with weights was built. The data of Household Budget Survey 2014/2015 will be ready in autumn 2016 afterwards they will be added to the basket and weights of the CPI 2015 starting at the beginning of 2017.


Pre-existing CPI series are traditionally chained so that historical time series can be directly compared with actual price trends. In this way price index series for long time periods are established enabling users to observe historical price trends and to apply them for indexation of long-term contractual monetary claims. Specifically, this means that the familiar CPI series continue to be calculated along the lines of the CPI 2015 and the given chaining coefficients (available only on the German Website).
