EXPLANATION OF TERMINOLOGY, CONTENT AND
CALCULATION METHODOLOGY OF SOME STATISTICAL

INDICATORS ON POPULATION AND LABOUR

POPULATION

Average population is the number of people on average for an

entire period (usually a solar calendar year), calculated by the
following formula:

rt
Pt = P0 × e
Where:

- Pt: Average population of calculated year;

- P0: Base year population;

- e: Natural logarithm, e = 2.71828;

- r: Population growth rate between the calculated time as
compared to the base time;

- t: Time duration from base time to calculated time (Number of
calculated years).

Urban population is the population of the territorial units which

is designated as urban areas by the State (wards, town).

Rural population is the population of the territorial units which
is designated as rural areas by the State (communes).

Population density is the average number of people per square

kilometer of the territorial area, calculated by dividing the population
(time point or average) of a certain residential area to the area of that
territory. Population density can be calculated for each province,
district, commune, etc. to reflect the population distribution by

geography at a given time.
