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

                            Number of households

                            Household is a social unit, comprising either one person living alone or
                        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.
