| The figures showing the size and structure of the population are derived from decennial population censuses and from additional information on population balances and changes. The latter is obtained by processing statistical reports on marriages, divorces, births, deaths and migration, which are provided by registries, district courts, stay registration offices, and aliens' registration office. Differences in the mid-year population figures for the years 1980-1981, 1990-1991 and 2000-2001 are due to differences between population and housing censuses and current balances. The figures on abortions are supplied to the Czech Statistical Office by the Institute of Health Information and Statistics of the CR. Notes on tables The tables include the population resident on the territory of the Czech Republic, irrespective of citizenship. Since 2001, the figures take account of the Population and Housing Census 2001 and include foreigners with the so-called long-term stay (i.e., the stay based on visas over 90 days, as stipulated by Act No. 326/1999 Coll.). Included are also marriages, births and deaths of the population residing in the Czech Republic, which occurred abroad. Table 4-1. Population and vital statistics Mid-year population: the number of inhabitants (males and females) as balanced as at 1 July of the reference year. Infant mortality: the number of children who died within 1 year of age per 1 000 live births. Neonatal mortality: the number of children who died within 28 days of age (i.e. at the age of 0 to 27 completed days of life) per 1 000 live births. Tables 4-10 and 4-12. Births The definition of a live birth is stipulated in Decree 11/1988 of the Ministry of Health of the CR: a live-born child child is a child who gives a sign of life (respiration, heartbeat, umbilicus pulsation, active movement of muscles) and whose birth weight is 500 g or more, or whose birth is below 500 g if it survives 24 hours after delivery. A stillborn child is a child not showing any signs of life, whose birth weight is 1 000 g or more. Table 4-11. Reproduction rates: by age of female Fertility rate by age: the number of live-born children per 1 000 females of a given age. Total fertility rate: the number of live-born children per 1 female throughout her whole childbearing period provided that the fertility rate remains the same as in the given year. Gross reproduction rate: the number of girls that would be live-delivered to 1 female throughout her childbearing period (from 15 to completed 49 years of age), provided that the fertility rate level remains the same in individual (normally single-year, in the table five-year) age groups as in a given year. Net reproduction rate: the number of girls that would be live-delivered to 1 female throughout her childbearing period (like in the gross reproduction rate above) and would live to see their mother's age in the years they were born. In order to maintain a stationary population into the future, the net population rate must be kept at 1 000. Abortion rate by age: the number of total abortions (i.e., of induced plus spontaneous abortions) per 1 000 females of a given age. Total abortion rate: the number of abortions per 1 female throughout her childbearing period provided that the abortion rate remains the same as in a given year. Pregnancies by age: the number of all pregnancies - i.e. the sum of live births and stillbirths and all abortions (induced and spontaneous) per 1 000 females of a given age. Total pregnancy rate: the number of pregnancies per 1 female, provided that her total fertility rate and her total abortion rate remain the same throughout her entire childbearing period as in a given year. Table 4-13. Abortions Decree 11/1988 of the Ministry of Health of the CR defines the abortion as the termination of a pregnancy in which:
a) the foetus does not show any sign of life and its birth weight is below 1 000 g or cannot be measured, if the pregnancy takes less than 28 weeks,
b) the foetus shows at least one of the signs of life and its birth weight is below 500 g, but it does not live longer than 24 hours after delivery,
c) the foetal egg without a foetus or gestational deciduas is removed out of the female's uterus.
Considered as abortions are also all cases of termination of pregnancy carried out as stipulated by Act 66/1986 (or by Act 68/1957 before 1987). Tables on abortions have been derived from source materials from the Institute of Health Information and Statistics of the CR.Table 4-15. Deaths: analysed by cause On 1 January 1994 the 10th decennial revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10), formerly the International Classification of Diseases, Injuries and Causes of Death (ICDICD), was put into use in the CR by Act 278/1992 of the Czech National Council. The organization responsible for its use in practice is the Institute of Health Information and Statistics of the CR. Unlike its 9th revision, the ICD-10 uses a four-character alphanumerical code consisting of one letter and three digits. However, a three-character alpha numerical code is employed for basic statistical treatment. The range of the causes of death has been considerably expanded, and the names and the order of causes of death have been changed, too. There is no full comparability between ICD-9 and ICD-10. Table 4-17. Expectation of life Expectation of life (ex) shows the number of years probably lived by an x-year-old person, providing that the survivorship function established by the life table remains unchanged throughout the x-year-old person's remaining life. Table 4-18. Internal migration: by type A change in a municipality of residence (or a district of residence in the case of Prague) within the territory of the Czech Republic is considered to be internal migration. Table 4-19. External migration: by country External migration refers to a change in the country of residence (or the long-term stay of foreigners), irrespective of citizenship.
The figures in the time series are comparable. All relative rates are calculated from actual figures without balancing.

Key population indicators resulting from the Population and Housing Census were published in the Statistical Yearbook 2002. Current figures on the number, structure and demographic migration of the population, including territorial breakdown by region and district, are shown in the following CZSO publications brought out according to the CZSO Catalogue of Publications 2003 (group 4 - POPULATION, ELECTIONS, subgroup 40 - Demography and subgroup 41 - Population and Housing Census): - "Population of the Czech Republic" (Czech-English version), quarterly, after the preliminary processing of results is finished
