In the process of demographic ageing, there is a new risk facing the population of industrialized countries: The risk of needing long-term care (LTC). For example, the number of individuals aged eighty and older (who are believed to be most exposed to this risk) is predicted to grow from 6.3 mn. (1992) to 17.7 mn. by the year 2040 in the U.S.A. and from 1.65 mn. (1991) to 2.3 mn. by the year 2030 in Germany, [see Eisen (1992) and Bundesministerium der Finanzen (1990)].
