Live birth: (according to the recommendation of the UN) a foetus is live-born if it gives any sign of life after birth (e.g. respiration, heart functioning or pulsation of umbilical cord), regardless of the length of pregnancy and the length of life after birth.
Total fertility rate: it expresses to how many children a female would give birth during her life at the birth frequency by age of the given year.
Death: final passing away of all signs of life at any time after live birth at any time, i.e. cessation of all life-functions without the capability of revival.
Marriage: contracted before the registrar acting officially in the presence of two witnesses.
Infant death: death after live birth and before the completed age of one year. Still-born infant and those deceased on the anniversary of the birth are not counted among infant deaths.
Natural increase (decrease): the difference between live births and deaths.
Population number: is calculated on the basis of the population census, for further calculation we take into account the data of the natural vital events (live birth, death) statistics and the international migration. The previously estimated population number is published once a year in the vital events first release of the January–December period.
Sources of data: vital events data collection implemented in accordance with Section 30 of Act CLV of 2016, and, in accordance with its Section 28, data transfers from the Electronic Register System.
