ஏழு ஆண்டுகளுக்கு முன்பே தமிழ்நாட்டில் வந்து குடியேறிய அயல் மாநிலத்தவர் எண்ணிக்கை சற்றொப்ப 44 லட்சம்(எந்த ஆவணங்களுமின்றி இங்கு வசிப்போர் இதில் அடக்கமில்லை).
மாணிக்கவாசகம் சீனி. அவர்களே நான் கீழே கொடுத்துள்ள தரவுகளில் எண்ணிக்கையில் தவறு இருந்தால் உரிய சான்றுகளோடு நிறுவுங்கள். போகிறபோக்கில் கதைவிடுகிறார்கள் என்று சொல்வது எவருக்கும் எளிது.
நான் அளித்துள்ளவைகள் பொய்யான தரவுகள் என்று தாங்கள் நிறுவிவிட்டால் வெளியார் சிக்கல் குறித்து பேசுவதையே நிறுத்திவிடுகிறேன்.

In 2001 the population is around 6.20 crores...
Decadal growth rate in TN is about 15%
So,
In 2011 the population should be around 7.10 crores.
2011 census almost reflects this...
In your calculation, you have used birth rate / death rate and calculated at simple interest rate for a decade.
Actually, you should calculate on compound rate on a year to year basis....

2001ல் மக்கள்தொகை சுமார் 6.20 கோடி..
பத்தாண்டு கால மக்கள்தொகை வளர்ச்சி சுமார் 15%
இதை 6.20 + (6.20 x 0.15) என்று கணக்கிட வேண்டும்...
2011ல் சுமார் 7.10 என்று சரியாக வரும்...்
நீங்கள் வருடாந்திர (பிறப்பு - இறப்பு) என்று சுமார் 0.8% என்று கணக்கிட்டு, மொத்தமாக சுமார் 8% என்று பத்தாண்டுகளுக்கு கணக்கிட்டு இருக்கிறீர்கள்.
இது தவறான கணக்கு.
நீங்கள் கணக்கிட்டு இருப்பது simple interest rate,
இது தவறு.
இதை compound rate of interest ல் வருடாவருடம் கணக்கிட்டு கூட்ட வேண்டும்....
புள்ளியியல் படித்வர்களிடம் கேளுங்கள்...
விளக்குவார்கள்....

How IT, auto boom made TN a cosmopolitan state
Updated: Jul 25, 2018, 10:41 IST
CHENNAI: Have you noticed the ‘October Fest’ in Besant Nagar and some other pockets of the city? The long queues in front of pandals, the smell of the delicious Kolkata street food, the poetry sessions going late into the night — a hint of Bengal right at the heart of Chennai. The seemingly ‘foreign’ environment is an indicator of the growing influx of Bengalis. Data on mother language released recently by Census 2011 shows the Bengali population in
Tamil Nadu has increased by 160% between 2001 and 2011. Since then, the trend has only accelerated.
Contributing to Tamil Nadu’s cosmopolitan tapestry of culture, languages and foods, the census showed that during the 10-year period people the number of Bengalis increased from 8,805 to 22,969. Following close behind were Hindi speakers, whose numbers went up from 1.89 lakh in 2001 to 3.93 lakh in 2011. Since the migration of people from West Bengal, north and northeast states is due to availability of employment, the trend in migration is an indicator of the state’s good economic health and its ability to create job opportunities in a range of industries and positions.
The boom in information technology and automobile industries brought in a large number of educated middle-class to the city. Since construction of IT parks and private establishments accelerated, daily wage workers in the realty sector also found work here. "The migration is not just from Kolkata or nearby districts, but from over West Bengal as well as from north-eastern states. And jobs have been available for all strata of society. A small indicator is that now I find non-Tamil waiters in almost all hotels in Chennai," said Madhumita Chatterjee, executive member of South Madras Cultural Association. While people employed in big companies settle in Chennai or other Tier-II cities on their own, workers in hotels or in the construction sector come through contractors.
According to a migrant worker survey in 2016, 20.9% of migrant workers in Tamil Nadu live in Chennai and Kancheepuram, being employed in firms such as Ford, Hyundai, BMW and Nissan. The top three districts —Kancheepuram, Chennai and Tiruvallur — are home to 51.3% of the migrant worker population.
Since textile and allied industries too are the other popular sectors, employing 1.5 lakh workers, Coimbatore has 12.1% and Tirupur 9% of the state’s migrant population. Manufacturing companies, real estate projects and metro rail work have also attracted workers in the past few years. Workers from north and eastern states are preferred, especially in construction business, say contractors. "While local workers start work at 9.30am and complete it at 5.30pm and get a pay of Rs800 per day. Workers from states like Uttar Pradesh, Bihar, Jharkhand and West Bengal work from 7am till 7pm, get Rs500 per day and food. They are also allowed to stay on the premises," said Ponn Kumar former head of Construction Workers Welfare Board.
The arrangement is mutually beneficial, as despite the relative lower pay migrant workers still get more than what they make back home. "We work for six months and send home not less than Rs8,000 to Rs10,000 per month. After six months we go back to our native place," said M Barman, a construction worker from North 24 Parganas in West Bengal.
Though the numbers of non-Tamil native speakers may have increased, the Tamil population percentage has not changed in the past decade. "Many people from southern districts of Tamil Nadu have migrated to Chennai and suburban areas and are employed in white as well as blue collar jobs, Similarly Tamils from other states who went for jobs there have also returned to their native," said international population expert P Arokiasamy.

MIGRATION patterns in India are increasingly reflecting the economic divide in the country, with more migrants over the last decade heading to the southern states, which have grown at a faster clip during this period.
According to Census data released on Thursday, southern states, especially Tamil Nadu and Kerala, have shown the highest increase in migrant population. With 45.36 crore migrants in India, every third citizen of the country is a migrant. Of these, 69 per cent are women, majority of whom have cited marriage or having migrated with their husbands as the reason for their translocation.

Watch what else is making news:
Migrants constitute 37.8 per cent of India’s 121.03 crore population. Over the last decade, the total number of migrants in India rose by 44.35 per cent from 31.45 crore in 2001. During the same period, India’s population grew 17.64 per cent.
The present study considers migrants by place of last residence — those who have last resided at a place other than their place of enumeration are deemed to be migrants. The study, however, does not point out whether these are interstate or intrastate migrants.
Tamil Nadu’s migrant population surged 98 per cent from 1.58 crore in 2001 to 3.13 crore in 2011. During the same period, the population of the state grew by 15.6 per cent. Migrants now constitute 43.4 per cent of the state’s population compared to 25.44 per cent in 2011. Kerala’s migrant population has grown by 77 per cent – from 0.92 crore in 2001 to 1.63 crore in 2011. The state’s population in the same period grew by 4.9 per cent. In Kerala, nearly 49 per cent of the population called themselves migrants as against 28.93 per cent in 2001.
Karnataka too has shown a 50 per cent increase in its migrant population – from 1.66 crore to 2.50 crore. Only Andhra Pradesh, with a 40 per cent rise in migrant population, has shown a growth below the national average — its migrant population increased from 2.34 crore to 3.32 crore during this period.
“The socio-economic development of the southern states is considerably higher and that attracts people. Another factor is that because of better education levels and awareness, local residents of these areas get drawn towards better economic opportunities. This vacuum that gets created gets filled up by people from outside. These developed areas face a crisis of manpower, especially for low-skilled jobs, which leads to migration,” says Dr Abdul Shaban, chairperson of the Centre for Public Policy, Habitat and Human Development at the Tata Institute of Social Sciences.
The only other states which have shown a higher growth of migrant population are Meghalaya and Manipur, where the number of migrants have grown by 108 per cent and 97 per cent respectively. For Jammu and Kashmir, it was 55 per cent and Assam 52 per cent.
While globally, migration is attempt by people to survive and prosper, in India, marriage appears to be the biggest reason why people migrate. Of the total 45.36 crore migrants, 22.39 crore or 69 per cent people referred to marriage being the reason for their migration. Only 5.07 crore (11.17 per cent) of the migrants termed work and business as causes, a marginal increase over 2001, where economic migrants stood at 10.39 per cent of the total.
While marriage remains the primary reason for women to migrate, the Census data shows that Indian women are also migrating for work and education. The number of Indian women who are economic migrants — moving for the sake of work, business or education — has grown by 129 per cent: from 0.51 crore in 2001 to 1.17 crore in 2011. During the same period, the number of male economic migrants grew by 51 per cent — from 3.09 crore to 4.7 crore.
