NCERT 9 GEOGRAPHY CHAPTER 6
6. POPULATION
- Population - the pivotal element in social studies
- Resources, calamities and disasters are all meaningful only in relation to human beings
- Census of India - official enumeration of population done periodically (for every 10 years)
- first census held in 1872, the first complete census held in 1881
POPULATION SIZE AND DISTRIBUTION
- India's population - 1210.6 million (as on march 2011) accounts for 17.5 % distributed over area of 3.28 million sq. km( 2.4 % of the world)
- Uttar Pradesh - the most populous state (199 million) - 16% of country's population
- Sikkim has a population of 0.6 million and Lakshadweep has only 64,429 people
- Rajasthan - the biggest state in terms of area, accounts only 5.5 %
- Half of India's population in 5 states - Uttar Pradesh, Maharashtra, Bihar, West Bengal and Andhra Pradesh
- Population density - Number of persons per unit area
- India - 382 persons per sq.km(densities vary from 1,102 per sq.km in Bihar to only 17 persons in Arunachal Pradesh)
POPULATION GROWTH
- change in the number of inhabitants of a country during a specific period of time
- From 1951 to 1981, the annual rate of population growth - steadily increasing (361 million to 683 million)
- Since 1981 the rate started to decline (low birth rates but the annual addition larger than ever before)
- If the total addition continue to grow, then India may overtake China in 2045 ( the most populous country in the world)
- Birth rate - Number of live births per 1000 persons in a year (always higher than death rates in India)
- Death rate - Number of deaths per 1000 persons in a year
- Till 1980, high birth rates and declined death rates resulting in higher rate of population growth
- Since 1981, birth rates also started declining, the growth rate declined (positive indicator of the efforts of birth control)
- Migration - movement of people across regions and territories.
- Migration can be internal (within the country) or international (between the countries)
- Internal migration cannot change the size of the population but change the composition (in terms of age and sex) and distribution of Population
- In India, people migrate from rural (poverty and unemployment) to urban areas (employment opportunities and better living conditions)
- Urban Population - 1951 (17.29%) to 2011(31.80%)
- From 2001 to 2011 - the number of 'million plus cities' (population with more than one million) increased from 35 to 53
- the number of people in different age groups
- Children ( below 15 years) - 34.4 %, economically unproductive, need to be provided with food, clothing, education and medical care
- Working age (15- 59 years) - 58.7%, economically productive and biologically reproductive
- Aged (above 59 years) - 6.9 %, can be economically productive (retired, some working voluntarily)
SEX RATIO
- Number of females per 1000 males
- social indicator to measure the extent of equality between males and females in a society
- Kerala - 1084 per 1000 males, Puducherry - 1038, Delhi - 866 and Haryana - 877
- According to 2011 census, literate - person with 7 years of age who can read and write with understanding in any language
- Total country's literacy rate - 73% (males - 80.9%, females - 64.6%)
- low levels of literacy - serious obstacle for economic improvement
- The distribution of population according to different types of occupation( primary, secondary and tertiary activities)
- Developed countries - their workforce in secondary and tertiary activities
- Developing countries - higher proportion of people in primary activities (64% population only in agriculture), secondary (13%) and tertiary sector (20%)
HEALTH
- affects the process of development
- Death rates declined - 1951 (25 per 1000 population) to 2011( 7.2 per 1000 population)
- Life expectancy increased - 36.7 years (1951) to 67. 9 years (2012)
- Because of improvement in public health, prevention of infectious diseases and application of modern medical practices in diagnosis and treatment of ailments
- Per capita calorie consumption is much below the recommended levels and malnutrition afflicts our population
- Still safe drinking water and basic sanitation amenities - available to only one-third of the rural population
ADOLESCENT POPULATION
- one-fifth of total Indian population
- age group of 10-19 years
- nutrition requirements of adolescents are higher than normal child or adult
- poor nutrition lead to deficiency and stunted growth
- In India, adolescent diets - inadequate in all nutrients (adolescent girls suffer from anemia)
The Family Planning Programme in 1952
- to promote responsible and planned parenthood
The National Population Policy 2000
- a people centred programme
- for imparting free and compulsory school education (upto 14 years)
