Statistical presentation
Data description

The population and its structures are defined as of 31.12. of the respective year. The population number and structures at the end of each year are calculated based on the previous year data and data on natural and migration increase during the reference year.

In the census years, recalculations of the population are done as of the end of the respective and the previous year. The recalculations are based on the census results and the respective calculations for the natural and migration increase, received from the current demographic statistics for the reference year.

The concept "permanent population" is applied in calculation of the population and its structures. The persons are included, permanently living in the country (having current address) as of 31.12. of the respective year and who have not been absent from the country for more than 1 year period.

Demographic projections (the population perspective projections) are calculations done under settled in advance conditions for the future development of the fertility, mortality and migration. They give an idea for the population development during the projected period. Different scenarios for the population projections are used depending on the expected social-economic development of the country.

Classification system

· Classification of Territorial Units for Statistical Purposes in Bulgaria (NUTS);

· Unified Classification of the Administrative-Territorial and Territorial Units in Bulgaria (UCATTU).

Sector coverage

The data on population number and structures cover persons permanently living at the country territory no matter their citizenship and status. The population territorial distribution (by settlements, municipalities, districts and statistical regions) is done according to the country administrative-territorial division as of 31.12. of the reference year and current address officially stated address of residence.

The last demographic projection elaborated by the NSI concerns the development of population up to 2080 with a starting point - the country population as of 31.12.2016 and takes into account the number of demographic events in 2017. The projection is prepared by single ages for each year within the period. Data is published for five-year periods.

Statistical concepts and definitions

Population as of 31.12.

Persons permanently living (having current address) in the country as of 31.12. of the reference year and who have not been absent for more than 1 year period.

The population number and structures at the end of each year are calculated on the basis of the population data for the preceding year and the data for natural and mechanical movement of the population during the current year.

Average annual population

The average annual number of population is average arithmetical value of the population at the end of previous and the end of reference year.

Natural change

The difference between the number of live births and the number of deaths during the reference year.

Natural increase rate

Calculated per 1 000 population and representing the difference between the number of live births and deaths during the year and the average annual population for the same year.

Migration growth

The difference between immigration into and emigration from the area during the year.

Net international migration is the difference between immigration into and emigration from the country.

Age

The population age is calculated as of 31.12. in completed years based on date of birth, i.e. the age reached at the end of the reference year.

Population under, at and over working age

The age limits used for distribution of the population under, at and over working age defined according to the annually updated retirement age, adopted by the Council of Ministers.

Age dependency ratio

Ratio of the number of persons under 15 years of age and number of persons 65 and more per 100 persons aged 15 to 64 years calculated in percentage.

Old age dependency ratio

Ratio of the number of persons aged 65 and more per 100 persons aged 15-64 years calculated in percentage.

Rate of demographic ageing

Rate of increase of the population over working age (according to the respective age limits for male and female) compared to the previous year calculated in percentage.

Demographic replacement rate

Ratio between the number of population aged 15 to 19 years (persons entering working age) and the number of population aged 60 to 64 years (persons leaving working age) calculated in percentage.

Statistical unit

Persons

Statistical population

Total population

Reference area

Regional breakdown of the population is done according to the country administrative-territorial division as of 31.12. of the reference year - settlements, municipalities, districts and statistical regions.

Statistical presentation
Data description

The population and its structures are defined as of 31.12. of the respective year. The population number and structures at the end of each year are calculated based on the previous year data and data on natural and migration increase during the reference year.

In the census years, recalculations of the population are done as of the end of the respective and the previous year. The recalculations are based on the census results and the respective calculations for the natural and migration increase, received from the current demographic statistics for the reference year.

The concept "permanent population" is applied in calculation of the population and its structures. The persons are included, permanently living in the country (having current address) as of 31.12. of the respective year and who have not been absent from the country for more than 1 year period.

Demographic projections (the population perspective projections) are calculations done under settled in advance conditions for the future development of the fertility, mortality and migration. They give an idea for the population development during the projected period. Different scenarios for the population projections are used depending on the expected social-economic development of the country.

Classification system

· Classification of Territorial Units for Statistical Purposes in Bulgaria (NUTS);

· Unified Classification of the Administrative-Territorial and Territorial Units in Bulgaria (UCATTU).

Sector coverage

The data on population number and structures cover persons permanently living at the country territory no matter their citizenship and status. The population territorial distribution (by settlements, municipalities, districts and statistical regions) is done according to the country administrative-territorial division as of 31.12. of the reference year and current address officially stated address of residence.

The last demographic projection elaborated by the NSI concerns the development of population up to 2080 with a starting point - the country population as of 31.12.2016 and takes into account the number of demographic events in 2017. The projection is prepared by single ages for each year within the period. Data is published for five-year periods.

Statistical concepts and definitions

Population as of 31.12.

Persons permanently living (having current address) in the country as of 31.12. of the reference year and who have not been absent for more than 1 year period.

The population number and structures at the end of each year are calculated on the basis of the population data for the preceding year and the data for natural and mechanical movement of the population during the current year.

Average annual population

The average annual number of population is average arithmetical value of the population at the end of previous and the end of reference year.

Natural change

The difference between the number of live births and the number of deaths during the reference year.

Natural increase rate

Calculated per 1 000 population and representing the difference between the number of live births and deaths during the year and the average annual population for the same year.

Migration growth

The difference between immigration into and emigration from the area during the year.

Net international migration is the difference between immigration into and emigration from the country.

Age

The population age is calculated as of 31.12. in completed years based on date of birth, i.e. the age reached at the end of the reference year.

Population under, at and over working age

The age limits used for distribution of the population under, at and over working age defined according to the annually updated retirement age, adopted by the Council of Ministers.

Age dependency ratio

Ratio of the number of persons under 15 years of age and number of persons 65 and more per 100 persons aged 15 to 64 years calculated in percentage.

Old age dependency ratio

Ratio of the number of persons aged 65 and more per 100 persons aged 15-64 years calculated in percentage.

Rate of demographic ageing

Rate of increase of the population over working age (according to the respective age limits for male and female) compared to the previous year calculated in percentage.

Demographic replacement rate

Ratio between the number of population aged 15 to 19 years (persons entering working age) and the number of population aged 60 to 64 years (persons leaving working age) calculated in percentage.
