Obyvatelstvo Olomouckého kraje

Methodology

The publication “Population of the Olomoucký Region in 2007“ is aimed to inform the readers on indicators characterising the demographic area from the aspect of regions. It is based on the publication “Demographic yearbook of the Czech Republic 2007“ (publication code 4019-08). Almost all tables are of the same structure as tables in Demographic yearbook of the CR, only the data are recalculated to regions. In addition, the publication offers tables for municipalities of the region with the most sought for indicators of population and vital statistics balances in municipalities with basic indicators of age structure. To obtain the entire review of regional demographic indicators the publication offers complete life tables for the Olomoucký region.

All data refer to the resident population of the Czech Republic, irrespective of citizenship. Since 2001, the figures also include (in accordance with the Population and Housing Census 2001) foreigners with long-term stay (i.e. the stay based on visa over 90 days, as stipulated by Act No. 326/1999 Coll.) and foreigners with granted asylum status (in compliance with Act No. 325/1999 Coll.). Since 1st May 2004, in accordance with amendment No. 326/1999 Coll., the figures include citizens of the European Union with temporary stay on the territory of the Czech Republic, and citizens of other countries with long-term stay. The data contain also information on events (marriages, births and deaths) of permanent residents of CR that occurred abroad.

Selected tables (A.01, A.02, B.01, B.02, C.01, D.01, E.01, F.01 and H.01) classified by territories are broken down by data for the region, size groups of municipalities by the number of population (size population groups) districts, administrative territories of municipalities with extended powers and data for cities.



Population and vital statistics in the Olomoucký Region for 1991 - 2007
Retrospective review of population and vital statistics in the Olomoucký Region includes events taken place on the territory of the region and recalculated to territorial structure as of 1 January 2006.

A. Population and vital statistics in 2007
Tables provide absolute and relative numbers.

B. Marriages
Except table B.02, all tables are territorially classified by residence of groom.

C. Divorces
Table C.01 lists all petitions for divorce filed, while the other tables contain information on divorced marriages only.

D. Births
Decree No. 11/1988 of the Ministry of Health of the CSR of 22 January 1988 defines a live-born child as a child fully expelled or removed out of the mother's body, who gives a sign of life and whose birth weight is (a) 500 g or more, or (b) lower than 500 g, if it survives 24 hours after delivery. The signs of life include respiration, heartbeat, umbilicus pulsation or active movement of muscles, even if umbilical cord is not interrupted or placenta delivered. A stillborn child is a child fully expelled or removed out of the mother's body, not showing any sign of life and whose birth weight is 1,000 g or more.

E. Abortions
The tables listing abortions are prepared from a set of individual data taken over by the CZSO from the Institute of Health Information and Statistics of the CR. The abortion is termination of 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 decidua is removed out of the female's uterus. Considered as abortions are also cases of termination of ectopic pregnancy or induced abortions carried out as stipulated in special regulations. The former were included under induced abortions in 1987 to 1991 and under other abortions as of 1992. On 1st January 1994, the Ministry of Health of the CR introduced new printed forms with more detailed nomenclatures of the marital status and education of women and these were applied in the processing without any adjustment. Unlike the tables brought out by the Institute of Health Information and Statistics, figures in this publication include abortions of all women residing in the CR (i.e. including foreigners).

G. Deaths by cause
The tables are arranged by the primary cause of death. On 1 January 1994 the 10th decennial revision of the International Statistical Classification of Diseases and Related Problems (ICD-10) was put into use in the Czech Republic 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 Czech Republic. The number of deaths in XIX chapter is equal to the number of deaths in XX chapter, as it is different classification of deaths by external causes. In XIX chapter deaths are classified by the primary cause (table G.05), while in chapter XX (table G.06) by the mechanism of death.

H. Migration
In this publication, migration refers to persons moving from their permanent residence in one administrative territory to permanent residence located in another administrative territory.

I. Population balance and analytic indicators
The chapter includes also detailed life tables from publications “Life tables for the CR and regions“ (4002-08).

J. Population by municipalities, 2007
Act No. 234/2006 Sb., On Municipalities, became effective as on 1 July 2006. Under this act, exceptionally, two new municipalities were set up, as of 1 July 2006, by separation of a part of municipality from the existing one. In the Olomouc Region, as of 1 July 2006, Držovice municipality was established by the separation thereof from Prostějov municipality.

Indicators

All indicators included in this publication refer to one calendar year. The calculation of indicators is based on demographic events or population which refer to the same calendar year. The population used for calculation of rates is the population at mid-year, defined as population as of 1st July of a given year. In all of the sets, the ‘age' (in terms of years, months or weeks) always refers to completed age. Only the length of life in days given for deaths of infants refers to the difference between the date of birth and the date of death. In the nuptiality life tables the ´age´ means the age at the begging of a period (1 January).

Late foetal mortality rate
The number of stillbirths per 1,000 total births.

Infant mortality rate
The number of deaths under 1 year of age per 1,000 live births.

Neonatal mortality rate
The number of deaths under 28 days of age per 1,000 live births.

Perinatal mortality rate
The number of stillbirths and deaths under 7 days of age per 1,000 total births.

Fertility rate by age (Age-specific fertility rate - fx)
The number of live births born to women at particular age (age group) per 1,000 women at given age (age group).

Total fertility rate (the sum of fertility rates by age)
The average number of children that would be born alive to a woman with presumption that age-specific fertility rates of a given year remain unchanged during her childbearing period (age 15-49).


Gross reproduction rate
The average number of girls that would be born alive to a woman with presumption that age-specific fertility rates of a given year remain unchanged during her childbearing period (age 15-49).



Abortion rate by age (Age-specific abortion rate - ax)
The number of abortions of women at particular age (age group) per 1,000 women at given age (age group).

Total abortion rate (the sum of abortion rates by age)
The average number of abortions per woman assuming that age-specific abortion rates of a given year remain unchanged during her childbearing period (age 15-49).


Pregnancy rate by age (Age-specific pregnancy rate)
The number of pregnancies of women (the sum of live births, stillbirths and abortions) at given age (age group) per 1,000 women at given age (age group).

Total pregnancy rate (the sum of pregnancy rates by age)
The average number of pregnancies per woman with presumption that age-specific pregnancy rates of a given year remain unchanged during her childbearing period (age 15-49).


Mortality rate by sex and age
The number of deaths of particular sex and at particular age (age group) per 1,000 population of given sex and at given age (age group).

Mortality rate by sex, age and chapter of causes of death
The number of deaths of particular sex and at particular age (age group) by particular chapter of causes of death per 100,000 population of given sex and at given age (age group).




COMPLETE LIFE TABLES INDICATORS

The complete mortality life tables are calculated from the third main group of demographic events, separately for males and females. There are based on the numbers of people (P) by age and sex as of 1 July of a year and the numbers of deaths (D) by age and sex during an analysed year.

Death probability (qx)
The probability that an individual at the exact age of x will die in a given period, i.e. will die before the exact age of x+1.


The function qx is derived from the age-specific mortality rates (mx) according the formula above. After equalization the function is further adjusted by Gompertz-Makeham formula (method of King-Hardy).

Probability of survival (px)
The probability that an x-year-old individual will not die in a given period and will survive to the age of x+1.


Table number of survivors (lx)
The hypothetical number of individuals alive at the exact age of x out of 100,000 live births (table root - I0), given the mortality conditions of the reference period.



Table number of deaths (dx)
The hypothetical number of individuals who die at the age of x.



Table number of person-years (Lx)
The hypothetical average number of individuals alive at the age of x; calculated as the average of two subsequent table numbers of survivors (except for the age of 0).


Auxiliary indicator (Tx)
The number of years of life to be lived by the table generation (not of an individual) at a given age.



Life expectancy (ex)
Indicate the expected remaining life duration with presumption of unchangeable mortality conditions of a given year. This synthetic indicator displays mortality conditions of a given year in all age groups.
