U5MR = 5 0  1000
B

Where:

U5MR: Under five mortality rate;

5D0: Number of deaths under age 5 in the reference period;
B: Total of live births in the reference period.

Natural increase rate of population is the difference between number of live
births and number of deaths to the population in the reference period. The natural
increase rate of population is expressed as a percentage or per mille.

Formula:
B - D
NIR = × 1000
Ptb

Where:
NIR: Natural Increase Rate of population;

B: Total number of live births in the reference period;

D: Total number of deaths in the reference period;

Ptb: Average population in the reference period.

Growth rate of population (growth rate) reflects the increase/decrease of the
population in reference period due to natural increase and net-migration. Growth rate
of population is expressed as a percentage or per mille.

In-migration rate are the number of people from different territorial units
(out-migration place) in-migrate to a territorial unit in the reference period
(usually a calendar year) on an average per 1,000 population of that territorial unit
(in-migration place).
