Data on population fertility and mortality provide information on number of births (in breakdown by sex, age of a mother, ethnicity, marital status of parents, etc.) and number of deaths (in breakdown by age, sex, ethnicity, citizenship etc.).

Definitions

The mean level of mortality in a given age group of population.

It is computed as a ratio of the annual number of deaths occurring at a given age during a year to the average annual number of persons at a given age.

It is usually expressed per 1000 population.

The average level of fertility of women at a definite age group.

It is calculated as the ratio of the annual number of births to women in a given age group over the average annual number of women of this age.

For the calculation of the birth rate for the age group up to 19 years, the denominator is the annual average number of women aged 15 to 19 years. For the calculation of the birth rate for the age group 15–49 years, the number of children born to women under and of 14 years of age, as well as for those of and over 50 is also included. It is usually calculated per 1000 women.

The ratio of the number of live births to the average number of population.

The rate is usually expressed per 1 000 people. 

The ratio of the number of deaths to the average number of population.

The ratio is usually expressed per 1000 people. 

Infant deaths are deaths that occur within the first year of life.

Beginning in 1991, data on infant mortality are given according to the World Health Organization (WHO) methodology, which slightly differs from the methodology used before. 

Age in the tables indicating number of deaths in breakdown by age has been calculated only basing on the birth year, thus number of deaths at age 0 differs from the number of deaths shown in the tables on infant deaths.

Natural increase is the difference between the number of births and the number of deaths in a given period of time.

Number of births registered in the Republic of Latvia during a year, if at least one of the parents is a permanent resident of the Republic of Latvia.

Starting from 2000 the number of births has been recalculated including also children born outside Latvia to mother (permanent resident of Latvia) temporarily being abroad. In compliance with the methodology of the Statistical Office of the European Union (Eurostat) these children should also be included in the number of children born in Latvia. 

Number of deaths registered in the Republic of Latvia during a year.

This number is not specified, if person in a longer time period is declared to be dead.

A foetus born dead after full 22 weeks of gestation.

The total fertility rate represents the average number of children that would be born to one woman during her lifetime if the age-specific fertility rate observed for that year would apply for her whole life.

Classifications

Information on fertility and mortality of population is compiled and published in compliance with:

  • Classification of Administrative Territories and Territorial Units of the Republic of Latvia (CATTU);
  • Classification of Ethnicities;

Data collection

Survey method and source data

Data on population fertility and mortality are acquired from the Information System for Registration of Civil Status Documents of the Office of Citizenship and Migration Affairs. 

Statistical processing

Calculation methods

Fertility and mortality demographic coefficients are calculated per 1000 average population of the corresponding period. If the total indicators are small, the rates can be calculated per 10 000 or 100 000 population.

Starting from 2000 the number of births includes also children born outside Latvia to mother (permanent resident of Latvia) temporarily abroad. In compliance with the methodology of the Statistical Office of the European Union (Eurostat) mentioned children should be included in the number of children born in Latvia.

Number of infant deaths includes children that have died during their first year of life. Data on infant mortality, starting from 1991, are given according to the WHO methodology, which slightly differs from the methodology used before. In tables on number of deaths the breakdown by age has been calculated basing on the birth year of the person, thus number of deaths at age 0 differs from the number indicated in infant mortality tables.

Data revision

In the second quarter of the following year monthly natural increase data of the previous year are updated in accordance with the specific date of event (during the year published in accordance with the registration date).  

Comparability

Comparability over time

Data on population fertility and mortality are comparable since 1946.
