Dependency index

Several indicators are calculated: - the share of persons aged 65 and over in the entity's total population - the dependency index: This is the ratio between the population aged under 20 or 65 and over (numerator) and the population aged 20-64 (denominator). An index of dependency 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 aged under 20 (denominator). An index above 100 indicates that the share of those over 64 in the population is higher than that of those under 20. - the intensity index of ageing: The age intensity index is the ratio of the population aged 80 and over (numerator) to the population aged 65 and over (denominator). It measures the share of older people (at greater risk of loss of autonomy) among those aged 65 and over.
