As far as possible the volume index of industrial output is calculated using volume data obtained from establishments. However, in some cases an establishment may not be able provide data on the volume of its output. In these cases, the establishment is asked for data on some other variables describing output, in other words proxy variables, that are considered as indicative of its volume. Examples of proxy variables include hours worked, raw materials consumed or value of output.
