Human Mortality Database (HMD)

Summary

The HMD is a clear and succinct database on mortality indicators, perfectly suitable for conducting studies on changes in life expectancy and longevity. One of the main advantages of the HMD is the standardisation and international comparability of the data. For the sake of comparability, general principles described in the Methods Protocol (available online) are followed for all populations in the HMD. However, exact uniformity of methods is not always possible because data at the required level of detail are not available in all situations. Therefore, in a few special cases, special methods to accommodate the realities of the available data were developed. Information on these special methods is accessible via the webpage.

Coverage of main and cross-cutting topics
The Human Mortality Database (HMD) was created to provide detailed mortality data to researchers, students, journalists, policy analysts, and others interested in the history of human longevity. The HMD contains original calculations of death rates and life tables for national populations, as well as the input data used in constructing those tables. The input data consists of death counts from vital statistics, plus census counts, birth counts, and population estimates from various sources. The data allows for comparative studies of mortality and analyses of time trends in mortality decline. It is also possible to use the data for assessing mortality risk among specific populations (i.e. by country, sex, age), as well for making mortality and population projections.

Linkage

Despite the different sources used (national providers), all the datasets are subjected to the same harmonisation criteria.
