This is a follow-up study to the paper presented at the 24 CIRET Conference in Wellington. The paper contains an updated and revised analysis of the applicability of survey data in monitoring systems based on barometric methods, devised to evaluate the current condition of the economy. The first part shows the use of survey data in macroeconomic barometers for Poland, developed by the author according to OECD standards. The second part compares various concepts of the synthetic indicator of business activity for Poland, filled with survey data. Some of the altemative variants refer to the EU concept of economic sentiment indicator (ESI) while other are more closely linked to the GDP concept. The choice of the most adeąuate formula requires further observation of the performance of altemative indicators over a longer time.
