How Biological factors that affect human population growth ? 

We have a look at some of the ways in which biological factors affect human population growth our. 

The biological loss underlying all the phenomena of population one society in advanced level of Technology in culture it is more meaningful explain what is sampling in terms of sociological economic and political influence. 

The study of population statistics in themselves is called demography all advanced countries now collect to detailed statistics on both marriages and deaths and every few years of Sciences of the population was taken in England these figures are published by the general register office in London world figures for population changes are much more difficult to come file because many under developed countries do not keep complete records however a very detailed list of the available statistics is published every year in the United Nation demographic year book .

From a careful study of these figures demographic save work out a description of what they think I found in the history of population of a modern industrial Nation throughout most of the women they believe man has had a very hard that great and the high birth rate the high death rate may have been due to in suicide a field in a disease or starvation but it was types of traditional tribal and present society was balanced by large numbers of birth the size of the population remained stable modern population in Africa and much of America and Asia examples of what may have been Universal in the past in these countries the very last for the portion of the population belong m's to an age group capable of becoming parents. This means, that compared with modern industrial countries the birthdate will be ready hai not only because human hair weave their families but because the proportion of an incredible of having children is also much higher. 

Please is the stage of high potential growth because of the death rate should be reduced the population would increase very rapidly in about 150 of the world .Modern medicine has reduced the death rate and hear the population explosion is greatest south-eastern Europe .Some South American countries and India are all more or less if the system is almost certain that many more countries will arrive at this situation by the end of the century the available statistic suggest that the modern industrial nuisance of the best passed through a face like this in the 19th century after this transitional growth stage III change to place in the Western Nations the birth rate begin to drop and by the 1937 North European countries had reached a new table level with low birth rate ke combined with low that in some countries the population declined and governments actively encouraged people to have more children. 

The three stage in the transition can be summarised in a graph listing Karenge India case there is very low level of productivity in the standard of living is very low at the middle is state agriculture becomes more productive that doesn't not always keep up with population growth and distribute Division III stage has a very high standard of living great efficiency and universal sophisticated Technology.
