Modern science was born around the year 1600. Scientists in Europe started to do experiments for testing their guesses and noted the results methodically. This is the Scientific Method and it resulted in rapid scientific progress. Some of the most important achievements are listed here.

Current Population of India – India, with 1,210,193,422 (1.21 billion) people is the second most populous country in the world, while China is on the top with over 1,350,044,605 (1.35 billion) people. The figures show that India represents almost 17.31% of the world’s population, which means one out of six people on this planet live in India. Although, the crown of the world’s most populous country is on China’s head for decades, India is all set to take the numero uno position by 2030. With the population growth rate at 1.58%, India is predicted to have more than 1.53 billion people by the end of 2030.

More than 50% of India’s current population is below the age of 25 and over 65% below the age of 35. About 72.2% of the population lives in some 638,000 villages and the rest 27.8% in about 5,480 towns and urban agglomerations. The birth rate (child births per 1,000 people per year) is 22.22 births/1,000 population (2009 est.) while death rate (deaths per 1000 individuals per year) is 6.4 deaths/1,000 population. Fertility rate is 2.72 children born/woman (NFHS-3, 2008) and Infant mortality rate is 30.15 deaths/1,000 live births (2009 estimated). India has the largest illiterate population in the world. The literacy rate of India as per 2001 Population Census is 65.38%, with male literacy rate at 75.96% and female at 54.28%. Kerala has the highest literacy rate at 90.86%, Mizoram (88.80%) is on the second position and Lakshadweep (86.66%) is on third.

India's Population in 2011Every year, India adds more people than any other nation in the world, and in fact the individual population of some of its states is equal to the total population of many countries. For example, Population of Uttar Pradesh (state in India) almost equals to the population of Brazil. It, as per 2001 Population Census of India, has 190 million people and the growth rate is 16.16%. The population of the second most populous state Maharashtra, which has a growth rate of 9.42%, is equal to that of Mexico’s population. Bihar, with 8.07%, is the third most populous state in India and its population is more than Germany’s. West Bengal with 7.79% growth rate, Andhra Pradesh (7.41%) and Tamil Nadu (6.07%) are at fourth, fifth and sixth positions respectively. The sex ratio of India stands at 933. Kerala with 1058 females per 1000 males is the state with the highest female sex ratio. Pondicherry (1001) is second, while Chhatisgarh (990) and Tamil Nadu (986) are at third and fourth places respectively. Haryana with 861 has the lowest female sex ratio.

Some of the reasons for India’s rapidly growing population are poverty, illiteracy, high fertility rate, rapid decline in death rates or mortality rates and immigration from Bangladesh and Nepal. Alarmed by its swelling population, India started taking measures to stem the growth rate quite early. In fact India by launching the National Family Planning programme in 1952 became the first country in the world to have a population policy. The family planning programme yielded some noticeable results, bringing down significantly the country’s fertility rate. In 1965-2009, the contraceptive usage more than tripled and the fertility rate more than halved. The efforts did produce positive results, however, failed to achieve the ultimate goal and the population of India since getting independence from Britain in 1947 increased almost three times. Whereas India has missed almost all its targets to bring the rate of population growth under control, China’s ‘One Child Policy’ in 1978, has brought tremendous results for the latter. The policy claims to have prevented between 250 and 300 million births from 1978 to 2000 and 400 million births from 1979 to 2010.

Major Changes Expected in UPSC Exams

3
upsc exam changes

UPSC is likely to bring some changes in Civil Services Exams, as various newspapers are reporting. The possibility of some key changes may be about optional subjects and upper age limit in this exams.

This news began with a reply to RTI query. The department of personnel and training (DoPT) said in response to an RTI query filed by a PTI correspondent that “The Baswan Committee’s report along with UPSC’s recommendations on it has been received on 20 March 2017, and the same is under examination.”.

Earlier, Minister of State for Personnel Jitendra Singh had told Rajya Sabha in a written reply in November last year that “The recommendations made by the committee including on pattern of civil service examination and age limit are presently under consideration of the UPSC”.

What is Baswan Committe?

The Union Public Service Commission (UPSC) had constituted an expert committee under the chairmanship of former human resource development secretary and retired IAS officer B.S. Baswan to review the scheme of civil service examination in August 2015.

Other Members of the Committee were:

  • R.K. Barik (Professor, IIPA)
  • Akber Ali (research Officer, IIPA),
  • Pankaj Kumar Singh (Research Officer, IIPA).

Game Changers Reccomendations UPSC

It is yet to be approved , announced and confirmed; but some likely changes as reported by various news agencies through their sources are related to Optional Subjects, Age limit etc.

1. The optional paper that the aspirants have to appear for may be completely done away with. This is being touted as a huge reform.

2. The committee is understood to have recommended a reduction in upper age limit of 32 years to appear in the civil service exam.

3. The UPSC has fixed a seven-day time frame for candidates to report mistakes or discrepancies in questions asked in the various examinations conducted by it.

It has been reported that it is widely believed in the official circles that the above key recommendations may be accepted.

Why these changes are important?

There is a huge difference in the award of marks in the optionals, scheme of awarding marks, while some subjects have innate advantages, and also, the availability of resouces such as coaching and study material, make some subjects more popular.

Possible uproar among apirants

  • Major contest may be seen on the age reduction issue as it has happened earlier.
  • Some aspirants feel the removal of optionals may work to the advantage of urban youngsters.
  • Also after removal of optional paper the exam would test their general knowledge and would be on other governance-related subjects like public administration and law.

Lakhs of aspirants appear in the civil service exam conducted annually by the UPSC in three stages–preliminary, main and interview–to select officers for Indian Administrative Service (IAS), Indian Foreign Service (IFS) and Indian Police Service (IPS), among others. From time to time various committees came with their recommendations to make it more competitive and updated.

Alagh Committee

Removal of Optional subjects would provide a level-playing field for all the aspirants since the cross-domain movement would reduce drastically. In fact, the Alagh Committee report in 2000 also suggested the same.

Alagh Committee recommended that the optional subject be removed from the mains while continuing the same in prelims. It also suggested that the Civil Services Aptitude Test (CSAT) be introduced.

Khanna Committee

The CSAT was introduced after the Khanna Committee report recommended the same in 2010. However, it was made just a qualifying exam after an uproar that urban aspirants and those educated in English medium had an edge in the CSAT.

Age Reduction in UPSC Exam

“The upper age limit has always been based on political expedience than the technical considerations.” – The Hindu

For many years, the upper age limit was 30 years for general category candidates, 33 years for OBCs and 35 years for SC and ST candidates.

But after the CSAT introducation uproar, upper age limit was increased to 32, 35 and 37 respectively for General, OBC and SC/ST categories. And also two additional attempts were awarded.

What aspirants expect from UPSC and DoPT?

The government  must give sufficient time window to existing aspirants is before reducing the age limit or changing the exam pattern. An advance notice is expeted from UPSC or DoPT. The change in pattern or age limit must not come all of a sudden in exam notification only.
