The Euro Spatial Diffusion Observatory (ESDO) database records face-to-face questionnaire surveys conducted between March 2002 and December 2011 in France, in December 2003 in Belgium and in December 2005 in Germany. The data provides information on the coins contained in the respondents' wallets at the time of the survey, classified by country of origin and value. A series of control variables provide information on the socioeconomic profile of the respondents and the location of their place of residence at the NUTS 3 level. In total, more than 22,500 people opened their wallets and about 300,000 coins were registered allowing the tracking of euro coins circulation from their country of introduction on January 1, 2002 (or later for countries that joined the euro zone afterwards) to their place of observation at the time of the survey.
