Concept Glossary

Concept selected: Base year


The base year of an index indicates the period to which the comparisons of different situations carried out refer. This means that generally, a base year relatively close to the current period is usually chosen, given that comparisons lose meaning when the comparison periods become spread apart. For this reason, it is advisable to periodically update the information relating to the base year, in other words, to change the base year so that the index does not become obsolete and lose meaning.
