Population

Selected Indicators - Methodological Notes

Mid-year population is the size of the population as of July 1 of the reference year.

A live-born child is a child showing at least one of the following signs of life at birth: breathing, beating of the heart, pulsation of the umbilical cord, active movement of muscles though the umbilical cord has not been cut or the placenta has not been born. At the same time, the birth weight is

    1. 500 and more grams or
    2. 499 grams and less and the child survives 24 hours after birth.

Abortion is premature spontaneous or artificially induced termination of pregnancy including extra-uterinepregnancy where the fetus does not show signs of life and its birth weight is below 1000 grams, or the fetus shows some sign of life and its birth weight is below 500 grams but it does not survive 24 hours, or if the weight of the fetus cannot be established and duration of gestation is below 28 weeks.

Induced abortion is artificially induced termination of pregnancy including extra-uterine pregnancy.

Spontaneous abortion (miscarriage) is spontaneous termination of pregnancy, i.e. an abortion due tobiological causes, without an obvious external intervention.

Natural increase in the population shows the difference between the number of live-born children and number of the deceased.

Net migration is the difference between the number of immigrants and the number of emigrants.

Total increase is the sum of natural increase and net migration.

Ageing index is represented by the number of persons aged 65 and over per 100 persons aged 0 to 14 years.

Mean age is the weighted arithmetic mean of the number of years lived by members of a given population until a given point in time; it is a mean age of the living population.

Total fertility rate is the mean number of live-born children per one woman throughout her whole reproduction period (from 15 to 49 years of her age), provided that the fertility rate level in the reference year was kept on and the mortality rate level was represented by the value of zero.

Gross reproduction rate is the mean number of live-born girls that would be delivered by one woman throughout the whole reproduction period (from 15 to 49 years of her age), provided that the fertility rate level in the reference year was kept on and mortality rate level was represented by the value of zero.

Net reproduction rate is the mean number of live-born girls that would be delivered by one woman throughout the whole reproduction period (from 15 to 49 years of her age), provided that the levels of fertility and mortality rates in the reference year were kept on.

Life expectancy at certain age (expectation of life) is the mean number of additional years a person of a given age would live if current mortality trends were to continue.

Life expectancy at birth is the mean number of additional years a person who has just been born would live if current mortality trends were to continue.
