Population

        Demography is the study of human populations. It encompasses the study of the size, structure and distribution of populations, and how populations change over time due to births, deaths, migration and ageing.
     
 
 
 
     Population means the number of people in a particular place.
But population of the world is not stable, it is growing at an increasing rate.
World population growth in the last 100 years has ben so rapid that it has been described as a population explosion.
    The world population is predicted to peak in 2200 at about 10.4 billion people and then stabilise.

    Population growth rates are not the same across the world: Population growth is low in MEDCs, and quickly in LEDCs.

    As a whole, population problems are very different in poor developing and economically developed countries.

   
This rapid population growth can cause problems in a country (over-consumption, famines, not enough jobs, lower standars of     living, forced migration...), therefore, many countries have chosen to control their population growth by promoting family planning or more direct methods (a restrictive birth policy). 

    But... why is the world´s population growing so rapidly?Why is population growth different across the world? What are the effects of population growth? Could Earth be able to carry this growth? How can population growth and resources be brought into balance? Which are the main issues on Population today?
