The project constists of a feasabilty study. The aim is to provide a set of different possibilites to measure the economic importance of the silver economy. As the term "silver economy" is neither clear cut nor part of any international classification system a definition is given. Available statistical information is analysed considering on the one hand differentitation opportunities and on the other hand the economic content of the silver economy. Given the available data base different quantification methods are proposed. The offered set of measures for the silver economy was finally assessed considering the usability for impact analysis, the evaluation of policy measures etc.
