Population growth is driven by birth rates exceeding death rates. While birth rates are high in developing countries, death rates have declined globally due to improved healthcare. The world population grew rapidly in the late 20th century and is projected to reach over 8 billion by 2028 and 10 billion after 2200. Population growth will be concentrated in developing regions, with Asia and Africa seeing substantial increases. Rapid urbanization and increased migration are also emerging trends with impacts on business and the environment like water scarcity and habitat destruction.

IN GENERAL , A TERM FOR THE NUMBER OF PEOPLE LIVING IN AN
AREA AT A PARTICULAR TIME
HOW CAN POPULATION GROWTH BE DEFINED ???
THE CHANGE IN POPULATION OVER TIME AND CAN BE QUANTIFIED AS
THE CHANGE IN NUMBER OF INDIVIDUALS IN A POPULATION AS “PER
UNIT TIME”. THE TERM POPULATION GROWTH CAN TECHNICALLY REFER TO
ANY SPECIES , BUT ALMOST REFERS TO HUMANS AND IT IS OFTEN
INFORMALLY , FAR THE MORE SPECIFIC DEMOGRAPHIC TERM POPULATION
GROWTH RATE.

16. PASHTUN TRIBES
WORLD POPULATION IS PROJECTED TO CROSS THE 8 BILLION MARK IN
2028; THE 9 BILLION MARK IN 2054
WORLD POPULATION NEARLY STABILIZES AT JUST ABOVE 10 BILLION
AFTER 2200
IT HAS TAKEN JUST 22 YRS FOR THE WORLD TO ADD THIS MOST RECENT
BILLION PEOPLE. THIS IS THE SHORTEST PERIOD OF TIME IN THE WORLD
HISTORY FOR A BILLION PEOPLE TO BE ADDED
WORLD POPULATION DID NOT REACH ONE BILLION UNTIL 1804. IT TOOK
123 YRS. TO REACH 2 BILLION IN 1927, 33 YRS. TO 3 BILLION IN 1960, 14
YRS. TO REACH 4 BILLION IN 1974 & 13 YRS. TO REACH 5 BILLION IN 1987
HIGHEST RATE OF WORLD POPULATION GROWTH (2.04 %) OCCURRED IN
THE LATE 1960S. THE CURRENT RATE (1995 – 2000) IS 1.31 %

17. PASHTUN TRIBES
THE LARGEST ANNUAL INCREASE TO WORLD POPULATION (86 MILLION)
TOOK PLACE IN THE LATE 1980S; THE CURRENT ANNUAL INCREASE IS 78
MILLION
THE 78 MILLION PEOPLE CURRENTLY ADDED TO THE WORLD EACH YEAR,
95% LIVE IN THE LESS DEVELOPED REGIONS
80% OF THE WORLD CURRENTLY RESIDES IN THE LESS DEVELOPED
REGIONS. AT THE BEGINNING O THE CENTURY, 70% DID SO. BY 2050, THE
SHARE OF THE WORLD POPULATION LIVING IN THE CURRENTLY LESS
DEVELOPED REGIONS WILL HAVE RISEN TO 90%
THE NUMBER OF PEOPLE IN THE WORLD AGED 60 OR OLDER WILL ALSO
RISE FROM THE CURRENT ONE – OF – TEN PERSONS TO BE TWO – OF –
NINE BY 2050
CURRENTLY AROUND ONE – OF – FIVE PERSONS IN THE DEVELOPED
COUNTRIES ARE AGED 60 OR OLDER; IN 2050 NEARLY ONE – OF EVERY –
THREE PERSONS WILL BE AGED 60 OR OLDER

18. PASHTUN TRIBES
WORLD LIFE EXPECTANCY AT BIRTH IS NOW AT 65 YRS , HAVING
INCREASED BY A REMARKABLE 20 YRS SINCE 1950; BY 2050 LIFE
EXPECTANCY IS EXPECTED TO EXCEED 76 YRS. HOWEVER, IN SPITE OF
THESE IMPRESSIVE GAINS, RECENT YEARS HAVE SHOWN DEVASTATING
TOLL FROM AIDS IN A NUMBER OF COUNTRIES
IN ADDITION, IN SOME EASTERN EUROPEAN COUNTRIES, HEALTH HAS
BEEN DETERIORATING AND MORTALITY, PARTICULARLY AMONG ADULT
MALES, HAS BEEN RISING
COUPLES IN DEVELOPED COUNTRIES TODAY HAVE ON AN AVERAGE 3
CHILDREN EACH, 30 YRS AGO THEY HAD SIX. MORE THAN HALF OF ALL
COUPLES IN THE DEVELOPING COUNTRIES NOW USE CONTRACEPTION
THE NUMBER OF PERSONS WHO HAVE MOVED TO ANOTHER COUNTRY
HAS RISEN TO ABOVE 120 MILLION MIGRANTS TODAY FROM 75 MILLION
IN 1965

19. PASHTUN TRIBES
THE WORLD HAS BECOME INCREASINGLY URBAN. CURRENTLY, AROUND
46 % OF THE WORLD POPULATION LIVES IN URBAN AREAS; THE
MAJORITY OF THE WORLD’S POPULATION WILL BE URBAN BY 2006
WORLD POPULATION GROWTH WILL BE CONCENTRATED IN
DEVELOPING COUNTRIES FOR THE FORESEEABLE FUTURE
POPULATION FOR ASIA, AFRICA, SUB SAHARAN AFRICA, MIDDLE EAST,
NORTH AMERICA AND SOUTH AMERICA WILL INCREASE SUBSTANTIALLY
POPULATION FOR EUROPEAN COUNTRIES AND FORMER SOVIET UNION
TENDS TO FALL FOR THE FORESEEABLE FUTURE
NOT MUCH DIFFERENT FOR THE POPULATION FOR OCEANIA AND BALTIC
REGION
