Calculation of Retail Sales Volume Index
Indices measuring retail sales are produced as both value (current prices) and
volume (constant prices) terms. As volume measurement is adjusted from
price effects, evaluated as Retail Sales Volume Index.
In calculation of Retail Sales Volume Index, Turnover Indices at current prices
are deflated by price relatives. For this purpose, CPI results produced at
"Classification of Individual Consumption by Purpose (COICOP)“
level are calculated according to NACE Rev.2 level. "Household Budget
Survey" data is used for this transition.
As a result of deflating current price Turnover Index by price relatives at
appropriate levels, Retail Sales Volume Index with constant prices is reached.
