The first price indices that were calculated in Spain go back to 1936 and these served as a base to establish the first Quality of Life Indices System that was maintained in force until December 1960. Subsequently two new systems entered into force with base years 1958 and 1968.

This system introduced significant novelties such as the classification of consumption into eight major groups and the creation of indices for each one of the Autonomous Communities. Since then another two CPI systems have existed with base years 1983 and 1992.

In January 2002 the CPI Base 2001 system entered into force.

The first indices in base 2006 were published in January 2007. The sample of municipalities increases in 25%, the number of prices collected increases 12% and the number of articles in the shopping basket increases to 491.

Similarly, others disappear whose consumption is no longer significant, such as recordable CD and movie rentals. .
