Population density is the average population per square kilometer of
the territory.
Population density is calculated by dividing the population (at time
point or average population) of a certain residential area to the area of that
territory.

Population density can be calculated for the entire country or region (rural,
urban, socio-economic region), for each province, district, commune, etc.
in order to reflect the population distribution by geography at a given time.

Formula:

Populationn density = Population
2
(persons/km ) Territory area

Number of households

a group of people living in the same dwelling and sharing meals together.
For households with 2 persons or over, its members may or may not share a
common budget; or be related by blood or not; or in combination of both.

Sex ratio of the population reflects number of males per 100 females.
Sex ratio of the population is determined by the following formula:

Sex ratio Total of males
of the population = Total of females × 100

Crude birth rate

Crude birth rate indicates that for every 1,000 people, how many live
births are in the reference period.

Formula:
B
CBR (‰) = × 1000
P tb

Where:
CBR: Crude birth rate;
B: Total live births in the reference period (total of children were born
alive in the reference period);
P tb: Population up to the reference time-point.
