Map of natural increase of world population


Natural increase (RNI) is the crude birth rate minus the crude death rate of a population.Usually developing countries have a positive or high natural increase rate.

Main migration waves


The United Nations defines migrant as an individual who has resided in a foreign country for more than one year irrespective of the causes, voluntary or involuntary, and the means, regular or irregular, used to migrate. 

World population distribution

The world population is the total number of living humans on Earth.Six of Earth's seven continents are permanently inhabited on a large scale.Asia is the most populous continent, with its 4.2 billion inhabitants accounting for over 60% of the world population.

Model of population cycle


The model of demographic transition progresses in four stages:Old or preindustrial demographic regime: it is characterized by high mortality rates and birth rates.First transition: Keep the high birth rate, but mortality drops.Second transition: the birth rate begins to decline, but mortality is still down more slowly.Modern demographic regime: Mortality rates and very low birth.

Population density


Population density is the number of people per unit of area usually per square kilometer or mile (which may include or exclude cultivated or potentially productive area). Commonly this may be calculated for a county, city, country, another territory, or the entire world.The world's population is 7 billion, and Earth's total area (including land and water) is 510 million square kilometers (197 million square miles).Cities with high population densities are, by some, considered to be overpopulated, though the extent to which this is the case depends on factors like quality of housing and infrastructure and access to resources.
