Birth registration is based on annual statistical information from civil registration documents on birth. The number of newborns includes only livebirths.

Child birth (livebirth) – since 1 January 2008 the concepts of “livebirth” and “stillbirth” correspond to WHO recommendations in Kazakhstan.,The following information is used for statistical purposes from birth registration documents: characteristics of the newborn – sex, date, and place of birth, birth order, single or multiple births, livebirth or stillbirth; mother’s characteristics – date of birth, age, nationality, education level, permanent residence, income source; records on the father, information on marital status (Annex 1 on state services standards provides for the “registration of child birth, including the introduction of changes, additions, and corrections to the civil registration documents” and was confirmed  by a decision of the Ministry of Justice of the Republic of Kazakhstan on 17 April, 2015, № 219, also called “on the approval of standards of state services for civil registration and apostille,” registered by the Ministry of Justice of the Republic of Kazakhstan on 17 June, 2015, № 11374).

Crude birth rate – an indicator that determines the number of livebirths among the population of a given geographical area during a given year, per 1 000 mid-year total population of the given geographical area during the same year. Usually, this indicator is expressed as the number of births per 1 000 persons.

Age-specific fertility rates are calculated as the ratio of the number of livebirths during a year by women of a specific age group to the average annual number of women of the same age. For the under-20 years age group,  the rate is calculated using the number of women aged 15-19 years old  as the denominator. For the 15-49 age group, the numerator comprises all births to women under age of 15 and to women aged 50 years and older.

Total fertility rate shows the average number of livebirths a woman would have during her reproductive period (15-49 years) if she were subject, throughout her life, to the age-specific fertility rates observed in a given year.  Its value does not depend on the age composition of the population and instead, characterizes the average fertility rate during a given calendar period. Total fertility rate is calculated as the average number of births to a woman of reproductive age and is a more accurate indicator of the birth rate than crude birth rate.

Life expectancy at birth – the average expected number of years a newborn is expected to live if current death rates do not change.
