According to the Public Statistical Surveys Program for 2020 and international practice, retail price levels do not include the category of result data from price surveys and consumer services, therefore, from the beginning of 2020, we stop publishing price results. This will also apply to annual data. The source of information on retail prices of goods and services presented are quotations conducted by interviewers at selected points of sale, in selected areas of research prices. Prices of goods and services are collected once a month, with the exception of fruits and vegetables, for which quotations are conducted twice a month (until 2010 - three times a month). Average monthly prices in the voivodship / country is calculated as the arithmetic mean of the quotations in the whole voivodship / country. Data not available for regions.
