Definitions and explanations
Population estimates from 2001 to 2020 were calculated on the basis of the 2011 Census, natural change and net migration data.
Population estimates from 2021 to 2022 were calculated on the basis of the 2021 Census, natural change and net migration data.
In the 2011 Census and 2021 Census, according to the international statistical standards, the concept of the place of usual residence is used in defining the total population. The place of usual residence is considered a place where a person normally spends the daily period of rest, irrespective of temporary absences from it (e.g. due to going on vacation, journey, medical treatment, visits etc.). According to the definition of the place of usual residence, the total population includes the following persons:
- those who have lived in their place of usual residence for a continuous period of at least 12 months before the census reference time
- those who arrived in their place of usual residence during the 12-month period before the census reference time with the intention of staying there for at least one year.
A live born child (live birth) is every child who at birth exhibits signs of life, such as breathing, beating of the heart, pulsation of the umbilical cord or definite movements of voluntary muscles.
A deceased person (death) is every live born person in whom there is a permanent disappearance of all evidence of life.
Natural increase is the difference between the number of live births and the number of deaths.
Data by age are expressed by completed years of age on the referent date. The data by age groups include persons who reached the age within the limits of an interval.
Immigrated or emigrated population is the population that changed their place of usual residence on the territory of the Republic of Croatia or that changed their country of usual residence for a period that is, or is expected to be, of a duration of at least one year.
Net migration of population (migration balance) is the difference between the number of immigrants and the number of emigrants of a particular area or country in a given period of time.
