Question
What are the three basic phases of population growth? Explain with reference to the theory of demographic transition.

Answer

There are three basic phases of population growth:
  1. The first stage is that of low population growth in a society that is underdeveloped and technologically backwards. Growth rates are low because both the death rate and the birth rate are very high so that the difference between the two is low.
  2. The third stage is also one of low growth in a developed society where both the death rate and the birth rate have been reduced considerably and the difference between them is again small.
  3. Between the two stages is a transitional stage of movement from backwards to an advanced stage and this stage is characterised by very high rates of growth population.

Read the passage given below and answer the following questions:
Population growth always outstrips growth in production of subsistence resources; hence the only way to increase prosperity is by controlling the growth of population. Unfortunately, humanity has only a limited ability to voluntarily reduce the growth of its population (through ‘preventive checks’ such as postponing marriage or practicing sexual abstinence or celibacy). Malthus believed therefore that ‘positive checks’ to population growth- in the form of famines and diseases- were inevitable because they were nature’s way of dealing with the imbalance between food supply and increasing population. Malthus was also criticized by liberal and Marxist scholars for asserting that poverty was caused by population growth. Critics argued that problems like poverty and starvation were caused by the unequal distribution of economic resources rather than by population growth.

Hospital deliveries on the rise, maternal deaths dip
New Delhi: Institutional deliveries, where children are delivered at health centres or hospitals, have picked up in India over the last five-odd years. Around 60 lakh more infants were born in safe confines of health care centres in 2010-11 as compared to 2005-06.
Experts say one main reason for this spurt is the Janani Suraksha Yojana (JSY), which was launched in April 2005, to reduce India’s shamefully high maternal and infant mortality rates. The JSY promoted institutional delivery among would-be mothers by providing cash assistance.
Emboldened, the Ministry has launched the Janani Shishu Suraksha Karyakaram (JSSK) this year. The initiative entitles all would-be mothers free delivery, free drugs and free diagnostics.
