Sources and processing

This data is based on the following sources

Human Mortality Database

The Human Mortality Database (HMD) is a research resource that provides detailed mortality and population data for national populations with high-quality vital statistics. It includes original calculations of death rates and life tables, as well as the underlying data — such as birth counts, death counts, and census-based population estimates — used to produce these metrics.

Its scope is limited to countries with virtually complete death registration and census coverage, mostly wealthy and industrialized nations. The database’s core mission is to document the historical rise in human longevity and support research into its causes and implications. HMD follows a rigorous, uniform methodology focused on transparency, reproducibility, and comparability, while acknowledging limitations such as age misreporting and data coverage issues.

Each country’s dataset is curated and quality-checked by dedicated researchers, ensuring reliability for demographic and public health analysis.

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

The birth data is constructed by combining data from multiple sources:

  • Before 1950: Historical estimates by Human Mortality Database (2024).

  • 1950-2023: Population records by the UN World Population Prospects (2024 revision).
