Share of 80 years and over

Several indicators are calculated: — the share of 65 years of age and over in the total population of the entity — the dependency index: This is the ratio between the population under the age of 20 or 65 years and older (numerator) and the population aged 20-64 (denominator). An index of dependence in below 100 indicates a larger share of the working-age population. — the ageing index: The Ageing Index is the ratio between the population aged 65 and over (numerator) and the population under 20 years of age (denominator). An index above 100 indicates that the share of people over 64 in the population is higher than that of those under 20. — the index of ageing intensity: The Aging Intensity Index is the ratio between the population aged 80 and over (digital) and the population aged 65 and over (denominator). It makes it possible to measure the share of older people (with a greater risk of loss of autonomy) among those aged 65 and over.
