Main Definitions of the Population
and Demographic Statistics

The total number of usual residents in a given territory at a given point in time. The population count is calculated as of 1 January, taking into account natural increase and net migration.

The arithmetic mean of the population at the beginning and end of the year (1 January of two consecutive years).

The level of settlement of a given territory, expressed as the number of usual residents per unit of total area (per 1 km²).

A settlement in whose territory industrial enterprises, tourist and resort establishments, or medical and socio-cultural institutions are located, and which serves as a local economic and cultural centre. Urban infrastructure is not primarily oriented towards agricultural activities.

A settlement whose boundaries mainly include agricultural land and other natural resources, and whose infrastructure is primarily oriented towards carrying out agricultural activities.

The population age is calculated as of 1 January, expressed as the number of completed years from the date of birth to the reference period.

The age that divides the population into two equal halves — one half is older than the median, the other half is younger.

Indicators characterising the age structure of the population:

The complete expulsion or extraction from the mother of a product of conception, regardless of the duration of pregnancy, which after separation breathes or shows any other sign of life — such as heartbeat, pulsation of the umbilical cord, or movement of voluntary muscles — whether or not the umbilical cord has been cut or the placenta is attached. Each such product is considered live-born.

A fetus whose death occurs prior to complete expulsion or extraction from the mother, regardless of the duration of pregnancy; the fetus does not breathe or show any other signs of life, such as heartbeat, pulsation of the umbilical cord, or contraction of skeletal muscle groups.

The ratio of male to female live births, showing the number of boys born per 100 girls.

The number of live births in a given period relative to the mid-year population of the same period.

The average number of births to women in a specific age group, expressed as live births per 1,000 women in that age group.

The average number of live births per woman over her lifetime (conventionally ages 15–49), based on the age-specific fertility rates of a given year.

The average number of births to women aged 15–19, per 1,000 women in that age group.

The average age of mothers at the birth of their children. Calculated as a weighted arithmetic mean of the interval between the birth of mothers and the births of their children.

The average number of live-born daughters per woman over her lifetime (conventionally ages 15–49).

The average number of live-born daughters per woman who will survive to the age at which their mother gave birth to them, under the reproduction conditions of the respective year.

The permanent cessation of all vital functions of an organism.

The mortality of live-born children during the first year of life (0–12 months).

Death from birth up to 28 days of life (0–27 days).

Death from the 28th day of life up to one year of age (28–365 days).

The average number of years a newborn could expect to live, assuming age-specific mortality rates of the given period remain constant throughout life.

The death of a woman while pregnant or within 42 days of the termination of pregnancy, irrespective of its duration or site, from any cause related to or aggravated by the pregnancy or its management.

The act of deliberately ending one's own life.

Indicators expressing mortality levels:

The number of deaths in a given period relative to the mid-year population of the same period.

The difference between the number of live births and deaths during a given period. Natural increase is negative when the number of deaths exceeds the number of births.

The difference between the crude birth rate and the crude death rate.

A person who left the country and, over the following 12 months, accumulated a minimum of 183 days of residence outside the country, and who was a usual resident of the country at the time of departure (i.e. had spent at least 183 cumulative days inside the country in the 12 months prior to leaving).

A person who entered the country and, over the following 12 months, accumulated a minimum of 183 days of residence in the country, and who was not a usual resident of the country at the time of entry (i.e. had spent at least 183 cumulative days outside the country in the 12 months prior to entering).

The difference between the number of immigrants and emigrants during the year.

The difference between the number of immigrants and emigrants during the year.

A voluntary union of a woman and a man for the purpose of creating a family, registered at the territorial offices of the Public Service Development Agency, a legal entity of public law under the Ministry of Justice of Georgia.

The number of registered marriages in a given period relative to the mid-year population of the same period.

The average age of persons at the time of marriage for a given period, calculated as the arithmetic mean of spouses' ages at marriage.

A legally significant act constituting one of the grounds for the termination of marriage between spouses, confirmed by the relevant individual administrative-legal act.

The number of registered divorces in a given period relative to the mid-year population of the same period.

The arithmetic mean of the differences between the years of divorce and marriage.
