–      deals with social characteristics of the population and their development through time

·         World Population Projections

o   has reached 7 billion on October 31, 2011

o   is projected to reach 8 billion by 2025

o   has doubled in 40 years from 1959 (3 billion) to 1999 (6 billion)

o   is currently growing at a rate of around 1.15 % per year

o   growth rate reached its peak in the late 1960s, when it was at 2%

o   growth rate is currently declining and is projected to continue to decline in the coming years

o   average annual population change is currently estimated at over 77 million

o   a tremendous change occurred with the industrial revolution: whereas it had taken all of human history up to the year 1800 for world population to reach 1 billion, the second billion was achieved in only 130 years (1930), the third billion in less than 30 years (1959), the fourth billion in 15 years (1974), the fifth billion in 13 years (1987), the sixth billion in 12 years (1999) and the seventh billion in 12 years (2011). During the 20th century alone, the population in the world has grown from 1.65 billion to 6 billion.

·         Properties of Population


1.genetically-based attributes of man

·         Human population geneticists have traced the origins and migration and invasion routes of modern humans, Homo sapiens. DNA comparisons between the present peoples on the planet have pointed to an African origin of Homo sapiens. Tracing specific forms of genes has allowed geneticists to deduce probable migration routes out of Africa to the areas colonized today. Similar studies show to what degree present populations have been mixed by recent patterns of travel.





2. sex composition


4. geographical distribution


6.birth and death rates
