Altersquotient

Altersquotient, in demography, is a demographic indicator that measures the balance between older and working-age people in a population. In its common form, it expresses the number of people aged 65 and over per 100 people aged 20 to 64, providing a snapshot of aging pressure on society and public finances.

Calculation and data sources: Altersquotient = (P65+) / (P20-64) × 100. Data typically come from census or population estimates, using mid-year populations. Some sources may use alternative age ranges for the working-age group, such as 15-64, or adjust the old-age threshold to 60+ depending on national definitions and available data.

Interpretation and use: A higher Altersquotient indicates a larger share of elderly relative to the working-age population, implying greater potential demand for pensions, healthcare, long-term care, and a smaller base of contributors to social security. It is used in policy planning and cross-country comparisons, though comparisons depend on the chosen age thresholds and labor participation rates.

Limitations: The Altersquotient is a crude indicator of aging and dependency. It does not account for labor force participation, retirement ages, health status, or migration. It can be affected by demographic factors such as birth rates and migration patterns, and differences in retirement policies. Consequently, comparisons across countries or over time should consider these contextual factors to avoid misinterpretation.
