Old-age dependency ratio

UN WPP

What you should know about this indicator

  • The old-age dependency ratio compares those aged 65 and over with the working-age population (aged 15 to 64).
  • This is a purely demographic measure. It does not count who is actually working or financially dependent — many people aged 15–64 are not in the labour force, and many people over 65 still are.
Old-age dependency ratio
UN WPP
The number of people aged 65 and over per 100 working-age people (aged 15 to 64).

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.

Notes on our processing step for this indicator

We compute the dependency ratios from the UN's population by age. The total dependency ratio is (population aged 0–14 plus population aged 65 and over) divided by population aged 15–64, multiplied by 100. The youth and old-age ratios use only the under-15 or 65+ numerators, respectively.
