Concept selected: Reference period of the expenses


The reference period of each good or service refers to the duration, in time, with which the observation of the expenditure on said good or service is made to correspond.
In terms of quality, it is very costly to research variables such as expenditure for a long period of time. For these reasons, reference periods are introduced.
Due to both the fatigue factor and the forgetfulness factor, this type of survey is associated with reference periods that, in general, do not ask households about all of their expenses during the entire study period, but rather, during a shorter period, in such a way that, applying a temporary elevation factor, an estimation of household expenditure throughout the study period is obtained.
