The world population is not evenly distributed since there are areas with high population density and areas with low population density
15
What is the density of population?
Population density is the relation between the number of inhabitants and the area they occupy.
15
Population density is calculated
by dividing the total number of people in an area by the area they occupy (in km²).
15
The most densely populated regions of the planet are:
East Asia, South Asia, Southeast Asia, the Middle East, the Gulf of Guinea, Western Europe, the East Coast of the United States, Central America and S...

Natural increase expresses
the difference between the number of births and deaths in a given period.
15
Birth rate relates
the number of births to the population of a territory and it is expressed in per mille
15
The crude birth rate (CBR) relates
the number of births to the total population in a year.
15
The fertility rate relates
the number of births to the female population of childbearing age (15-49).
15
The birth rate depends on
the fertility rate
15
The crude mortality rate indicates
the number of deaths in relation to the total population ( per mille)
15
The infant mortality rate formula relates
the number of deaths of children under one year of age in a population of one thousand registered live births.
15
Life expectancy
is the average number of years a given population lives in a certain period of time.
15
The dynamics of any population are influenced by
the natural increase and by migrations.
15
Migrations
are movements that can be domestic(within a country) or external or international (from one country to another or from one continent to another)
