New Data Byte: Tobacco usage in India is highest among older people, by @nileena_suresh About one in four Indians over the age of 15 reported smoking or using some form of tobacco as of 2021, according to the National Family Health Survey 2019-21. However, there is a significant divide in tobacco consumption between younger and older adults. Across the population, over one in three Indians in their 40s and 50s consume tobacco, compared to just half that share among those in their 20s. The gap is particularly striking among men. Over half of Indian men in their 30s and 40s consume tobacco, whereas the share is just over a quarter among men in their 20s. Tobacco consumption is much less common among women. Overall, just 4% of women consume tobacco in some form. However, even among women, prevalence increases with age, reaching about 17% among women aged 50 and above. Tobacco is consumed in many forms, the most common being paan masala or gutkha, followed by cigarettes, khaini and bidis. Across age groups, chewing tobacco like gutkha, paan masala and khaini is more common than smoking. About two-thirds of tobacco users consume these products, while around half smoke bidis or cigarettes. Regardless of the form, tobacco has serious health consequences and is a major risk factor for serious non-communicable diseases, like cancers, heart disease and respiratory illnesses. This generational gap is observed globally. Across most countries, younger people are less likely to use tobacco than their older counterparts. #Tobacco #Gutkha #Health #India #DataForIndia

Climate across India is influenced by factors such as latitude, elevation, land use, proximity to the coast and atmospheric circulation. These geographical differences mean that warming affects different seasons and regions differently. Using daily gridded temperature data from the India Meteorological Department (IMD), we analyse mean temperature anomalies across India for the 2015-2025 period relative to the 1991-2020 climatological baseline. Since temperatures naturally vary across India, anomalies offer a more consistent way to compare warming across regions and over time. Negative anomalies (shown in blue) indicate temperatures cooler than the baseline average, while positive anomalies (shown in red) indicate warmer-than-baseline conditions. Winter in India shows the most geographically widespread warming of all four seasons, with positive anomalies across almost the entire country. This means that our winters are becoming warmer, and nearly all states show temperatures above the 1991-2020 average. Warming is strongest in north-western India. Parts of Rajasthan, Gujarat, Punjab, Haryana, Himachal Pradesh, Jammu and Kashmir, and Ladakh show anomalies exceeding +0.5°C, locally approaching +1.1°C. The central and southern states, including Maharashtra, Telangana, Andhra Pradesh, Karnataka, Tamil Nadu and Kerala, show smaller increases of around +0.2°C to +0.5°C. Warmer winter conditions have important implications for rabi agriculture, which is particularly sensitive to rising temperatures. They can also increase crop water stress and alter irrigation requirements. #Heat #GlobalWarming #Winter #Temperature #India #DataForIndia

🧵 Data For India was at @IndiaFOSS in Bengaluru this September! Over the two days of the conference, we spoke with over a thousand free and open source software enthusiasts about our work and making public data easier to understand and use. At our booth, @nileena_suresh and @TheDataAreClean guided visitors through hands-on activities, inviting them to make guesses about India and compare their answers with the data. The responses opened up many conversations about the gap between data being publicly available and being useful to people. #FOSS #OpenSource #DataForIndia

As incomes rise and access to education and healthcare improves, women around the world have chosen to have fewer children. India, too, has seen a stunning decline in family sizes over the last 50 years. In the early 1990s, over a quarter of Indian mothers had more than five children. By 2021, this share was down to 10%, with most mothers having two or fewer children. This shift is also reflected in the decline in India’s Total Fertility Rate (TFR), a demographic indicator that estimates the average number of children that a woman will have in her lifetime. In 1971, India’s TFR was 5.2, meaning that a woman in India was expected to have 5.2 children on average over her lifetime. India’s TFR had dropped to 1.9 by 2023. As a result of this falling fertility, large families are increasingly rare in India. Families with a larger number of children are more likely to be poorer, and mothers in these families are more likely to have lower levels of education. This suggests that as incomes continue to rise and access to education continues to grow, the share of large families will fall further. #Population #Fertility #TFR #India #DataForIndia

In 1950, a child born in India could expect to live only until the age of 41. By 2024, life expectancy at birth in India had risen to 72 years. Life expectancy is the average number of years a person would live if they were exposed to the sex- and age-specific death rates prevailing at that time. This data for India and other countries comes from the World Population Prospects, 2024 Revision, published by the United Nations Population Division. Across the world, women tend to live longer than men owing to a combination of biological and social factors. Girls are more likely to survive infancy and early childhood, while men are more likely to die from accidents in young adulthood and non-communicable diseases in old age, partly because of differences in health behaviours. However, this global trend did not hold true in India in the first few decades of Independence. In the 1950s, Indian men lived longer than women. That male advantage was reversed only in the early 1980s. By 2024, a newborn girl could expect to live more than three years longer than a boy born in the same year. This female advantage is large and well established only in India’s richer states. In poorer states, it is smaller and more recent. #LifeExpectancy #Ageing #Population #India #DataForIndia

Six in ten workers in India are self-employed, making up the largest category of workers. India's labour statistics define the self-employed as persons who operate their own farm or non-farm enterprise, or are engaged independently in a profession or trade on their own, or with one or a few partners in household enterprises. Unlike salaried and casual workers, the self-employed are not paid wages, but their earnings come from the profits of the enterprise. Workers with lower levels of education are much more likely to be self-employed, while those with a higher education are more likely to be in salaried work. Among workers who have a higher education, 40% are in self-employment, while nearly 60% are in salaried work. Among illiterate workers, on the other hand, 66% are self-employed while just 7% are in salaried work. Self-employed people may be own-account workers who run their own enterprise without employees, employers who run the enterprise by hiring paid employees, or unpaid helpers who work in a household enterprise for no wages. #Employment #SelfEmployment #Work #India #DataForIndia

When a country’s Total Fertility Rate (TFR) drops to 2.1 children per woman, demographers say it has reached “replacement fertility”. This is a key milestone for a country, indicating that the population will eventually stop growing and replace itself. If fertility falls further, the population will decline in absolute numbers over time. India's fertility rate has dropped to 1.9 children per woman as of 2023. In the global conversation around falling birth rates, choices made by women around education and work are usually seen as the leading cause. However India shows that this theory does not hold universally.    In North America, Europe and East Asia, falling fertility could in part be explained by the opportunity costs faced by women who leave the workforce to have children. But most adult women in India do not work for pay outside the home. Yet India’s birth rate is now comparable to Viet Nam’s, where the labour force participation rate for women is two times that of India. The age at which women have their children is also lower in India than in East Asia, North America or Europe, meaning that women delaying childbirth for their careers is also not an explanation for falling fertility here.  In their 2025 book, After the Spike: Population, Progress, and the Case for People, economists Dean Spears and Michael Geruso argue against a grand theory for this trend. Instead, they suggest that many types of improvements in people’s lives have raised the opportunity cost of having children. These may include economic opportunities, but they may also include more leisure, and more ways to spend one’s time.  #Fertility #Births #Population #India #DataForIndia

New Data Byte: More pre-teens in India have used the internet than people in their 40s, by @akwaghmare Internet usage in India is heavily concentrated among younger people. Of the 60% of Indians who had used the internet as of 2025, most are in their teens and twenties. Internet usage among people in their thirties and forties, on the other hand, is much lower. Fewer than half of people in their 50s, and fewer than a quarter of people over the age of 60 use the internet. In contrast, nearly all Indians in their late teens and in their twenties use the internet.  This data comes from the Comprehensive Modular Survey - Telecom, a nationally representative survey conducted by India's National Statistics Office. The survey asked people who reported they had used a phone or a computer whether they were able to use the internet, and whether they had used the internet at least once in the three months preceding the survey. A substantial number of children have also used the internet. More than half of children between five and nine years of age (54%) reported having used the internet at least once in the three months preceding the survey. Children between five and nine years of age are more likely to have used the internet than people in their fifties. Access to the internet increased sharply during the COVID-19 pandemic, particularly among children and teenagers, likely as a result of lockdowns and online schooling.  #Internet #Teenagers #LivingConditions #India #DataForIndia

Infant mortality, or the death of a child before her first birthday, is a key measure of public health. It reflects the conditions into which children are born, including access to healthcare, nutrition and sanitation. Infant Mortality Rate (IMR) is the number of deaths of children under the age one for every 1,000 live births in a given year. India's IMR in 2023 was 25 deaths for every 1,000 live births, which is nearly 638,000 infants under the age of one who died in India in that year. Within infancy, it is the first week that is the most precarious. Over half of all infant deaths occur in the first week after birth, or in the early neonatal period. While both neonatal (within the first month) and post-neonatal (from the infant's second month to the end of the first year) mortality have declined in India, the decline in mortality rates after the child's first month has been sharper. The share of deaths within the first month has increased from 61% in 2003 to 73% in 2023, meaning that infant deaths are fewer, but are increasingly concentrated in the earliest days of life. #Infant #Deaths #Mortality #Health #India #DataForIndia

New Data Byte: A higher education is associated with a significant wage premium in India, by @akwaghmare One in six Indian workers is a salaried or a regular wage worker. Labour statistics define salaried or regular wage employment as the working arrangement in which employees who work in enterprises owned by others are paid their wages on a regular basis, generally from the same employer.  The wages of salaried workers between 25 and 50 years of age gradually increase with each new year of completed formal education. Here, formal education begins in Grade 1, and a child completes one year in formal education when she successfully clears the first grade. But this increase in wages comes in distinct stages. For workers with zero to seven or eight years in formal education, there is little change in earnings. This means that completing the primary level of education does not raise income levels. The first significant increase in wages is seen for workers who spent 11 or 12 years in education, equivalent to completion of high school. Beyond that, wages continue to gradually rise for workers with every additional year of completed education, meaning that they are enrolled in a higher education programme. The largest increase in wages, however, is for workers with 16 or more years of education. This is equivalent to the completion of a four-year undergraduate programme. Salaried workers with a higher education earn twice that of those with secondary education, and thrice that of those with only primary education.  #Education #Salary #Work #India #DataForIndia

Access to mobile phones and the internet has grown rapidly in India, but many people still lack the technical skills needed to communicate, learn and work effectively using these technologies. More than half of Indian adults can send messages, including on WhatsApp, but only a quarter can send emails. One in five can install or configure software and hardware, or transfer files between devices. More advanced skills are far less common. Fewer than one in ten Indian adults can use spreadsheets or create presentations. Only 1% of Indians report the ability to code.  These trends in ICT skills may partly reflect India’s mobile-first digital adoption. More than eight in ten adults can use mobile phones, but only two in ten can use computers. India is a signatory to the United Nations Sustainable Development Goals (SDGs), one of which is to substantially increase the proportion of young people and adults with information and communication technology (ICT) skills by 2030. The Indian National Statistics Office's 2022-23 Comprehensive Annual Modular Survey (CAMS) collects this data on the prevalence of nine ICT skills listed in the SDGs.   #ICT #Technology #DigitalIndia #India #DataForIndia

New Data Byte: The gap in life expectancy between India and the UK has halved since Independence, by @Rukmini In 1950, a child born in India could expect to live only until the age of 41, while a child born in the United Kingdom the same year could expect to live to 69 years. Life expectancy at birth is the average number of years a newborn would live if they were exposed to the sex- and age-specific death rates prevailing at that time. This is a hypothetical measure that assumes current mortality rates will remain constant throughout the individual's life, providing a snapshot of a population's overall health and mortality conditions at that time. Data on life expectancy for the countries of the world is periodically estimated by the United Nations Population Division. In 1950, India was one of the world's poorest and least developed countries. By 2024, not only had life expectancy in India gone up to 72 years, but the gap between India and the UK had also narrowed substantially, to now being less than a decade apart. The only recent time that life expectancy in India slid backwards was during the COVID-19 pandemic, when life expectancy fell in most countries, reflecting the prevailing health conditions at the time. By 2022, life expectancy was back to its pre-pandemic levels, & on the path to growth, once again.  #Population #LifeExpectancy #DataByte #India #DataForIndia

India's informal sector has remained large over the last two decades despite economic growth. Nine in ten workers in India work in the informal sector, defined as either share of employment outside the formal sector or as informal employment. Most sectors in India still rely largely on informal workforces. The agricultural sector employs the largest number of workers but is almost entirely informal. However, a few sectors, mainly in services, are relatively more formalised.  Public administration, including defence, and information and communication services have the highest share of formal employment, with over four in five jobs in these sectors being formal. A majority of jobs in health and education, as well as in real estate and financial and professional services, are also formal. On the other hand, more than 50 million jobs in manufacturing are informal, compared to nearly 13 million formal jobs. Along with manufacturing, the construction sector and trade enterprises such as commercial shops and wholesale traders have the highest number of informal workers, with over 70 million workers each. #Jobs #InformalSector #Work #India #DataForIndia

New Data Byte: Most tobacco consumption in India is of gutkha, not cigarettes, by @nileena_suresh The majority of tobacco use in India is of chewing tobacco products such as paan masala, gutkha, or khaini. Gutkha is pre-mixed paan masala with tobacco. Paan masala is also sold separately and mixed with tobacco later to be consumed. Since most tobacco consumption in India is by men, we look at the type of tobacco usage by men. About 40% of men aged 15-49 use tobacco in some form, compared to just 5% of women, according to the National Family Health Survey, 2021. Tobacco use in India as measured by the NFHS includes smoking cigarettes or bidis, as well as chewing tobacco products such as khaini (tobacco leaves mixed with slaked lime), paan masala, gutkha, and other similar preparations. Since respondents may use tobacco in more than one form, the NFHS does not measure consumption of these products as discrete categories. More than a quarter of men chew tobacco products, while under one in five men smoke bidis or cigarettes. Tobacco usage is higher in rural areas, and the form of usage also differs, with cigarette smoking more prevalent among urban men. Both forms of tobacco have major health impacts, including life threatening conditions like cancer of the oral cavity, oesophagus and liver, as well as heart diseases and respiratory illnesses.  #Tobacco #Gutkha #Health #India #DataForIndia

🧵 The term 'demographic dividend' refers to a boost in economic growth that a country with a large share of its population in the working age can expect to benefit from, provided the right policies are in operation. This dividend comes not just from the size of the working-age population, but, more importantly, from its relative share in the total population. Two demographic shifts have been reshaping India. First, as fertility rates fall, the share of children (0-14 years) in the population is declining. Second, the elderly population is growing in size. Together, these trends have expanded India’s working-age population (15–60 years) – the only age group that, in economic terms, generates resources and drives growth. But that window is now closing. The working-age population according to Indian demographic statistics makes up over 60% of the population, and is projected to reach its peak over the next three to four years, after which it is projected to decline. In some parts of India, this decline has already begun; in the decade ahead, the southern states will see their working-age populations begin to shrink, even as the north-central states will see their working-age populations continue to grow. #Births #Deaths #Fertility #Population #India #DataForIndia
