Life expectancy data are calculated basing on summary mortality rates of males and females in 5-year age groups (number of deaths per 1 person at corresponding age and of corresponding sex). Life expectancy indicators are calculated with the help of software Mortpak-Lite developed by the United Nations Statistics Division.


Life expectancy at a defined age is the mean number of years to be lived by the survivors to a defined age, provided that the mortality conditions remain the same as in the year when the calculation was made.

Life expectancy at birth is the mean number of years an infant may expect to live if the mortality rates for each population group in the given year remained constant. The data is obtained from the mortality and life expectancy tables.

Data collection

Survey method and source data

Data on life expectancy of population are acquired with the help of calculations based on the CSB information on population mortality, average annual number of usually resident population as well as sex and age structure of the population.

Statistical processing

Calculation method

Life expectancy estimates are based on crude, male, and female death rates in breakdown by five-year age groups (number of deaths per one resident of the respective gender and age). Until 2000, age of the person at death was calculated according to the birth or calendar year (death year minus birth year). As more statistical information is available, since 2000 the age of the person passed away is calculated in full years (from the birthday until the day of death). Starting from 2000, the death rate and life expectancy statistics calculations are based on the age of the person passed away in full years. The life expectancy estimates are made by using the Mortpak-Lite software developed by the United Nations Statistics Division.

Data are verified by comparing indicators on longer time period, observing trends of indicator changes and using graphical analysis.


Comparability over time

Comparable data on life expectancy of population are available since 1958.

International comparability


The Statistical Office of the European Union (Eurostat) compiles and publishes on its website demographic statistics on the EU and on each individual country: Statistics/ Population and social conditions/ Population/ Data/ Main tables.
