4. A population is a summation of all the organisms of the
same group or species, who live in the same geographical
area, and have the capability of interbreeding.[1][2] In
ecology the population of a certain species in a certain
area is estimated using the Lincoln Index. The area that
is used to define a sexual population is defined as the
area where inter-breeding is potentially possible between
any pair within the area. The probability of interbreeding
is greater than the probability of cross-breeding with
individuals from other areas. Under normal conditions,
breeding is substantially more common within the area
than across the border.[3]
5. The demographics of India are inclusive of the second
most populous country in the world, with over 1.21 billion
people (2011 census), more than a sixth of the world's
population. Already containing 17.5% of the world's
population, India is projected to be the world's most populous
country by 2025, surpassing China, its population reaching
1.6 billion by 2050.[4][5] Its population growth rate is 1.41%,
ranking 102nd in the world in 2010.[6] Indian population
reached the billion mark in 2000.
India has more than 50% of its population below the age of 25
and more than 65% below the age of 35. It is expected that, in
2020, the average age of an Indian will be 29 years, compared
to 37 for China and 48 for Japan; and, by 2030,
India's dependency ratio should be just over 0.4.[7]
6. FACTORS AFFECTING POPULATION
THERE ARE THREE MAIN FACTORS FOR CHANGE OF
POPULATION.THEY ARE:BIRTH RATE
DEATH RATE
MIGRATION
THE NATURAL INCREASE OF POPULATION IS THE
DIFFERENCE BETWEEN BIRTH RATES AND BEATH RATES
PLUS POSITIVE AND/OR NEGATIVE MIGERATION(i.e.
PEOPLE MIGRATING INSIDE THE COUNTRY AND PEOPLE
MIGARATING OUTSIDE THE COUNTRY.
7. BIRTH AND DEATH RATES
BIRTH RATE IS THE NUMBER OF LIVE
BIRTHS PER THOUSAND IN A YEAR.IT IS A
MAJOR COMPONENT OF GROWTH BECAUSE
IN INDIA,BIRTH RATES HAVE ALWAYS
BEEN HIGHER THAN THE DEATH RATES.
DEATH RATE IS THE NUMBER OF DEATHS
PER THOUSAND IN A YEAR.THE MAIN
CAUSE OF THE RATE OF GROWTH OF
INDIAN POPULATION HAS BEEN THE
RAPIUD DECLINE IN DEATH RATES.
8. MIGRATION OF PEOPLE
MIGRATION REFERS TO THE MOVEMENT
OF PEOPLE FROM ONE PLACE TO another
in search for jobs and land
INTERNAL MIGRATION DOES NOT
CHANGES THE SIZE OF THE
POPULATION BUT INFLUENCES THE
DISTRIBUTION OF POPULATION
WITHIN THE NATION. IN INDIA, MOST
MIGRATION HAS BEEN FROM RURAL TO
URBAN AREAS BECAUSE OF THE “PUSH”
FACTOR IN RURAL AREAS.
