Methodology
3. POPULATION
The basic figures showing the size and distribution of population are derived from housing and population censuses and from additional statistical balances on births, marriages, divorces, deaths and migration.
All the published indicators show definitive figures relating only to the population resident in the given area (irrespective of citizenship).
Mid-year population: the number of inhabitants in the given area as balanced as at 1 July of the reference year.
The population is broken down into one-year age groups, or into five-year age groups in the abridged version, or possibly into even broader ones – e.g. children under 14, working-age population between 15-59, etc. In demographic statistics, the age of a person refers to the completed age at the moment of survey, i.e. the age of the last birthday.
A live-born child is 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.
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.
In demographic statistics, abortions are premature terminations of pregnancy, classified by a physician as abortion-terminated pregnancies. Basic data on abortions are monitored by health authorities, which provide information for the CZSO through the Institute of Health Information and Statistics of the Czech Republic.
Expectation of life shows 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 is 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.
In this Yearbook, migration refers to migration of persons from their permanent residence in one administrative territory to permanent residence located in another administrative territory.
In demographic statistics, marriage refers to an event of entering into marriage reported by Registry offices by means of statistical report. Data on divorces are provi
