Statistical presentation
Data description

The births and the children born are surveyed. Registration is done at the moment of occurrence and the number is calculated as of 31.12 of the reference year. Live births and stillbirths are covered.

Source of data on births and children born is the Unified System for Civil registration and Administrative Service of Population. Births are registered through a common USCRASP-CDS document "Birth notification".

Regional breakdown of the fertility data is done according to the country administrative-territorial division as of 31.12 of the reference year (settlements, municipalities, districts and statistical regions) based on the current address.

Live births are used for calculation of indicators, characterizing the fertility.

Classification system

· Classification of Territorial Units for Statistical Purposes in Bulgaria (NUTS);

· Unified Classification of the Administrative-Territorial and Territorial Units in Bulgaria (UCATTU).

Sector coverage

All children born with a usual residence (current address) in the Republic of Bulgaria are included.

Statistical concepts and definitions

"Birth” is a complete expulsion or extraction from the mother of a foetus, irrespective alive or dead, that meet the following criteria: not

a) body weight at birth of 800 grams and over and / or 26 weeks of gestation;

b) body weight at birth of less than 800 grams and / or less than 26 weeks of gestation - provided that the foetus was born alive and has lived at least 3 days.

"Alive" is a foetus who shows signs of blood circulation. In absence of such signs, the foetus is considered “dead” (foetus mortuus).

“Abortion” is a loss or interruption of a pregnancy before the foetus to meet the above mentioned criteria. 

Crude birth rate is the ratio of the number of live births during the year to the average annual population in that year. The value is expressed per 1000 inhabitants.

The total fertility rate is the sum of the age-specific fertility rates for the reference year. It represents the mean number of children that would be born alive to a woman during her lifetime if she were to pass through her childbearing years conforming to the fertility rates by age of a given year.

The net reproduction rate is the ratio between the number of women who have gave a birth during the year and the daughters born during the same year taking into account the mortality. It represents the average number of daughters that will survive until childbearing ages, born to a woman if they will experience the age-specific fertility and mortality rates of the year in question, i.e. how many girls replace a mother under the reproduction conditions during the respective year.

The age of parents at birth is calculated in completed years based on the date of birth of parents and the date of event birth.

The mean age of the mother at childbearing is calculated as a weighted average within the interval between the birth of mothers generations and children birth.

Statistical unit

Children born - live born and stillborn.
