The GfK Panel Household is a continual study of household habits in Croatia and more than 20 countries around the world. Using the expert approach and the saturation method, GfK uses the data collected through this research to explain the location of goods of broad support, market changes and foresee future trends. Thanks to the SmartScan application developed for the needs of the Household Panel, we can find out which products are being purchased in Croatia. Such information helps large companies make decisions about improving the quality of existing products and introducing new ones, and all that you as customers are more satisfied with. The Household Panel is a continuous research that is in Croatia for more than 17 years.
