Purpose

This indicator reflects the relative weight of the population aged 65 years and over in the general population of a country or geographic area and is required to estimate a series of demographic indicators, such as the dependency ratio.

The indicator reflects the state of health and the degree of aging of a given country or geographical area.

The information is used for planning, management and evaluation of public policies related to health and social security, especially for older adults.

Method of estimation

For countries with a population greater than 90 thousand inhabitants, the figures are estimates from the United Nations, based on data that represent values estimated as of July 1st, obtained by linear interpolation of the corresponding five-year population projections of the United Nations, using the medium-variant projections.

For countries with less than 90 thousand inhabitants, the figures are estimates from the US Census Bureau International Database. The US Census Bureau population projections are based on the cohort component method.

For the proportion of the Population 65 and over by sex, the rate is calculated with the total population of the respective sex. The rate was calculated by PAHO.

Interpretation example

According to 2018 data, 5.4% of country A were 65 years or over, that is, for every 100 people residing in this country during 2018, five were 65 years or over.

Disaggregation  
Limitations

The international comparability of this indicator may be affected by the periodicity of population censuses and demographic surveys. Population censuses are generally carried out every 10 years and surveys have a frequency that varies between different countries, and the sampling error also influences quality. The value of the indicator also depends on the adequate coverage of the civil registration system (greater than 90%), on the fact that deaths and births are registered in the information system in a timely manner, and on the integrity of the national registry.

Estimated figures of this indicator may differ from the statistics made by countries due to factors such as methodological differences, for example, to produce population estimates and projections.
