The document outlines various population metrics, including population density, birth rate, mortality rate, infant mortality rate, natural growth, and net migration rate. Each metric is defined by specific formulas using inhabitants, area, and annual figures. These metrics are essential for understanding demographic changes and trends.

1. Population rates

2. Population density
P.D. =
number of inhabitants
area
(in square kilometres (km2
))

3. Birth Rate
B.R. =
number of births in a year
* 1,000
total population for the year

4. Mortality Rate
(Death Rate)
M.R.
/ D.R.
=
number of deaths in a year
* 1,000
total population for the year

5. Infant Mortality Rate
I.M.R. =
number of deaths of infants
(less tan one year old)
* 1,000
number of live births in the same year

6. Natural (Population) Growth
N.G. =
births - deaths
* 100
total population for the year

7. Net Migration Rate
N.M.R. = inmigrants - emigrants
