POPULATION GROWTH, SIZE AND DISTRIBUTION

POPULATION SIZE AND DISTRIBUTION

•    People are themselves resources with varying qualities.
•    Population is the point of reference from which all other elements are observed and from which they derive significance and meaning like resources, calamities, disasters etc.
•    The Census of India provides us with information regarding the population of our country.
•    Census is an official enumeration of population done periodically. In India census is held every 10th year.
•    Uttar Pradesh accounts for about 16 per cent of the country’s population.
•    India’s population as in March 2001 stood at 1,028 million accounting for 16.7 per cent of the world’s population.
•    Almost half of the India’s population lives in just five states. These are Uttar Pradesh, Maharashtra, Bihar, West Bengal and Andhra Pradesh.
•    Population density is calculated as the number of persons per unit area.
•    Population density is affected by relief of the area.

Population Growth   

•    The numbers, distribution and composition of the population are constantly changing. Hence population is a dynamic phenomenon.
•    Growth of population refers to the change in the number of inhabitants of a country/territory during a specific period of time.
•    Since 1982 India’s population growth rate is on the decline.
•    When more than a billion people increase even at lower rate, the total numbers added becomes very large.
•    The declining trend of the growth rate is indeed a positive indicator of the efforts of birth control.
•    The natural increase of population is the difference between birth rates and death rates.
•    The number of deaths per thousand persons in a year is the Death Rate.
•    Migration is the movement of people across regions and territories.
•    Migration can be internal and international.
•    Migration changes not only population size but also the population composition of urban and rural populations in terms of age and sex composition.
•    Pull and push are the factors responsible for migration.
