Under five mortality rate is the measure of mortality level of
children in the first five years of life. This rate is defined as the number
of deaths of children under age 5 per 1,000 live births in the reference
period on average.

Where:

U5MR: Under five mortality rate;
D : Number of deaths under age 5 in the reference period;
5 0
B: Total of live births in the reference period.

Natural growth rate of population is the difference between
number of live births and number of deaths compared to the average
population during the reference period, or the difference between the
crude birth rate and the crude death rate of population in the reference
period.

Where:

NIR: Natural growth rate of population;

B: Number of live births in the reference period;
D: Number of deaths in the reference period;

P: Population up to the reference time-point;
CBR: Crude birth rate;

CDR: Crude death rate.
Total growth rate of population (or "population growth rate")
reflects the increase or the decrease of the population in one period

expressed as a percentage.

In-migration rate reflects the number of people from different
territorial units (out-migration place) in-migrates to a territorial unit in
