Ageing of the Population
Some communities in the Alps have a very high proportion of elder people (Source: J. HEEB).
A population is described as excessively aged when the proportion of people over 60 years of age makes up more than 15% of the total population (BÄHR 2004 in PSAC (PERMANENT SECRETARIAT OF THE ALPINE CONVENTION) 2007).
The Old Age Index provides information about the demographic structure of a region. It is defined as follows: number of people over 64 per 100 people under 15 (GAVRILOV & HEUVELINE 2003 in PSAC 2007).
In the year 2000, there was 17% of the Alpine population that was over 64 years of age. By comparison, the proportion of those over 64 in the EU-25 was 16.3%. EUROSTAT expects that the proportion of those over 64 will double in the EU by 2050. People over 64 years of age will then make up approximately one third of the population.
In the year 2000, in 63% of all municipalities in the Alpine Convention, the proportion of those older than 64 years of age was over the 15% threshold. This means that the population can be described as excessively aged in almost two thirds of all Alpine municipalities. Ageing of the population is particularly high in the cities and in the smallest communities. Of the municipalities that experienced population decrease, 82% are now excessively aged (see PSAC 2007).
The Old Age Index for municipalities in the Alpine Convention was 100.3 in the year 2000. This means that the number of people over 64 is approximately equal to the number under 15. The areas with the highest Old Age Index are in the Italian Alps (Liguria/I: 241), while those with the lowest value are Liechtenstein (63), Vorarlberg/A (64), Rhône-Alps/F (70) und Tyrol/A (73) auf (see Map 6).
The highest Old Age Index can be observed in the 'balanced' (194) and in the 'other' (187) municipalities, whilst the lowest values are in the ‘urban’ (105) municipalities. The total sample here is only 5,590 municipalities due to limited data availability
