What is population density in Vietnam? How to calculate population density?
Based on population and population density indicators (T0102, H0102, X0102) guided in the Appendices promulgated together with Decision 05/2023/QD-TTg, population density is defined as follows:
- Population density is the average number of inhabitants per square kilometer of the territory of Vietnam.
- Population density is calculated by dividing the population (time population or average population) of a given population by its territorial area.
- The population density of each province, district and commune in order to reflect the geographical distribution of population at a certain time.
- Calculation formula: Population density (people/km2) = Number of population (people) / area (km2)
What are the regulations for subdivisions of population indicators when carrying out statistical work in the locality of Vietnam?
Based on population and population density indicators (T0102, H0102, X0102) guided in the Appendices promulgated together with Decision 05/2023/QD-TTg, the subdivision of population indicators is implemented as follows:
(1) Age
Age is the length of a person's life from the date of birth to a certain time. In the census, age is calculated as the number of round years (excluding odd days and months) and is often referred to as a round age.
The round age is determined as follows:
If the month of birth is smaller than (occurs before) the survey month:
Round Age = Year of Inquiry - Year of Birth
If the month of birth is greater than (after) or coincides with the month of the investigation:
Round age = Year of inquiry - Year of birth - 1
(2) Marital status
Marital status is determined as follows:
- Unmarried, or never married: A condition of a person who has never been married or has never lived with someone of the opposite sex as a spouse.
- Spouses: A person's status that is currently recognized by local laws or customs or customs as having a spouse or living with someone of the opposite sex as a spouse.
