WHAT DOES POPULATION ACTUALLY MEANS ??? 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.

INTRODUCTION

TWO THINGS THAT AFFECT THE POPULATION

SIZE OF THE WORLD

BIRTH RATES

IS THE NUMBER OF BIRTHS FOR EVERY 1,000 PEOPLE.

IN ECONOMICALLY DEVELOPING COUNTRIES, THE BIRTHRATE IS HIGH.

IN WEALTHY INDUSTRIALIZED COUNTRIES, THE BIRTHRATE IS LOW.

BIRTH RATES

DEATH RATES

IMPROVED DIET AND HEALTH CARE HAVE LOWERED THE DEATH RATE IN MANY INDUSTRIALIZED NATIONS

ARE THE NUMBER OF DEATHS PER YEAR IN 1,000 PEOPLE.

DEATH RATES

WORLD POP IS GROWING RAPIDLY BECAUSE BIRTHRATES HAVE NOT DECLINED AS FAST AS DEATH

RATES.

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 %

THE WORLD AT BILLION : EMERGING TRENDS

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

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

THE WORLD AT BILLION : EMERGING TRENDS

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

THE WORLD AT BILLION : EMERGING TRENDS

SOCIAL• SERVICES LIKE HEALTHCARE AND EDUCATION

CANT COPE WITH THE RAPID INCREASE IN

POPULATION , SO NOT EVERYONE HAS ACCESS TO

THEM.• CHILDREN HAVE TO WORK TO HELP SUPPORT

THEIR LARGE FAMILIES , SO THEY MISS OUT ON

EDUCATION.• THERE AREN'T ENOUGH HOUSES FOR EVERYONE,

SO PEOPLE ARE FORCED TO LIVE IN MAKESHIFT

HOUSES IN OVERCROWDED SETTLEMENTS. THIS

LEADS TO HEALTH PROBLEMS BECAUSE THE

HOUSES AREN'T ALWAYS CONNECTED TO SEWERS

OR THEY DON’T HAVE ACCESS TO CLEAN WATER.

• THERE ARE FOOD SHORTAGES IF THE COUNTRY

CANT GROW OR IMPORT ENOUGH FOOD FOR

THE POPULATION.

RAPID POPULATION GROWTH : EFFECTS

POLITICAL• MOST OF THE POPULATION IS MADE UP OF

YOUNG PEOPLE SO THE GOVERNMENT FOCUSES

ON POLICIES THAT ARE IMPORTANT TO YOUNG

PEOPLE E.G. EDUCATION AND PROVISION OF

THINGS SUCH AS CHILDCARE.

• THERE ARE FEWER OLDER PEOPLE SO THE

GOVERNMENT DOESN’T HAVE TO FOCUS ON

POLICIES THAT ARE IMPORTANT TO OLDER

PEOPLE E.G. PENSIONS.

• THE GOVERNMENT HAS TO MAKE POLICIES TO

BRING POPULATION GROWTH UNDER CONTROL

SO THE SOCIAL AND ECONOMIC IMPACTS OF

RAPID POPULATION GROWTH DON’T GET ANY

WORSE.• .

RAPID POPULATION GROWTH : EFFECTS

ECONOMIC

• HIGH PERCENTAGE OF SENIOR

CITIZENS IN DEVELOPED

NATIONS• DRAMATIC CHANGES IN SIZE

OF WORKFORCE• SHIFT IN CONSUMER

PREFERENCES• FINANCIAL STRAIN CAUSED BY

PENSIONS• .

RAPID POPULATION GROWTH : EFFECTS

RAPID POPULATION GROWTH : EFFECTS

EFFECTS ON BUSINESS

IMMIGRATION• CAUSED BY UNEMPLOYMENT

RESULTING FROM POPULATION GROWTH

• DEVELOPING NATIONS MAY LOSE MOST PRODUCTIVE CITIZENS

• BUSINESSES MAY EXPAND INTO DEVELOPING NATIONS• LESS EXPENSIVE LABOR FOR

BUSINESSES• PROVIDE EMPLOYMENT FOR

CITIZENS OF DEVELOPING NATIONS
