3. POPULATION The basic figures showing the size and age distribution of the population are derived from population and housing censuses and from additional statistical balances on births, marriages, divorces, deaths and migration. All the published indicators show final figures on the population with permanent residence in the given area (irrespective of citizenship). The data since 2001 reflect the Housing and Population Census 2001 results and also include foreigners who were granted long-term stays (i.e., foreigners with visas over 90 days, as stipulated by Act No. 326/1999 Coll.). Using the results obtained by the processing of the Housing and Population Census 2001 a new demographic projection of the Czech Republic also including calculations for the regions has been drawn up. Its key results are given in Table 3.3. The projection for the CR’s regions does not include migration effects and thus shows hypothetical development of the size and distributions of the population in the region affected by natural population changes. Mid-year population: the number of inhabitants in a given area as balanced as at 1 July of the reference year. Age of person: In demographic statistics it the refers to the completed age at the moment of survey, i.e., the age at the last birthday. Dependency ratio: the ratio of the number of inhabitants aged 65+ to the number of children under 15. Live-born child: a child who gives at least one sign of life and whose birth weight is 500 g or more, or whose birth weight is below 500 g if it survives 24 hours after delivery. Total fertility rate: the number of live births per one female provided that the fertility rate remains the same throughout the female’s whole childbearing period as in the year given. Total abortion rate: the number of abortions per 1 female throughout her childbearing period provided the abortion rate remains the same as in a given 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 complete days of life, per 1 000 live births. Abortions: In demographic statistics, they refer to premature terminations of pregnancy, classified by physician as abortion-terminated pregnancies. The data on abortions are taken over from the Institute of Health Information and Statistics of the Czech Republic. Life expectancy: the number of years probably lived by an x-year-old person if the survivorship function established by the life table remains unchanged throughout the x-year-old person’s remaining life. Natural increase in population: the difference between the number of live-born children and the total number of deaths in the given area in the reference year. Total increase of population is the difference between the initial population and the final population. Total increase comprises natural increase plus net immigration. Migration: in this Yearbook, it refers to migration of persons from their permanent residence in one administrative territory to permanent residence located in another administrative territory. Marriages are included in the respective area according to the groom’s place of permanent residence or the bride’s place of permanent residence where the groom’s place of permanent residence is abroad. Divorces are monitored on data provided to statistical authorities by courts of justice.
