The difference in life expectancy at birth among separate years is due to relatively small number of population and deaths in some statistical regions and the different age structure of the deceased in each year.
Razlike v pričakovanem trajanju življenja ob rojstvu med posameznimi leti so posledica relativno majhnega števila prebivalcev in umrlih v nekaterih statističnih regijah ter različne starostne sestave umrlih v posameznem letu.
