Is it time to celebrate India's 'improved' sex ratio? Reasons to question NFHS data

By Aditi Chaudhary*
The recently published National Family Health Survey (NFHS) factsheet brought cheers amongst the public and the government. With Child Sex ratio (number of females per 1000 males in the age group 0 - 6 years) and overall sex ratio (the total number of females per 1000 males), both showing an improvement, NFHS-5 (2019-21) got applauded by all around.
The World Health Organization (WHO) recommends the sex ratio to be 952 females per thousand males. An ideal scenario of sex ratio tends to be 1:1 owing to various factors such as natural selection at birth and others. The child sex ratio increased from 919 in NFHS-4 (2015-16) to 929 females per 1000 males in NFHS-5 (2019-21). Further, there is also an improvement in the Sex ratio of the total population from 991 females to 1020 females per 1000 males.
It is unprecedented and commendable for India to overcome all the biases and discrimination that women face and acquire a healthy sex ratio. The numerical excess of women over men while facing social evils like female foeticide, female infanticide and dowry deaths is welcome. This increase is the paradigm shift that the government and stakeholders have strived for.
However, the sex ratio mentioned by NFHS-5 cannot be truly considered to show the actual change. The 2011 Census had reported the sex ratio to be 940 females per 1000 males, and NFHS-5 shows 1020 females per 1,000 males.
Some reasons to question the phenomenal increase in sex ratio in the last decade are as follows:
First of all, one should understand the national-level survey's definition to calculate the sex ratio. It uses modified de facto enumeration It enumerates people based on “where they spent the last night prior to the day of enumeration”.
Here, we cannot deny the possibility of rural men and women being away from their homes on the last night of the enumeration. Men not present at the time of the survey, presumably for work or other reasons, could have also led to inflation of the sex ratio.
Then, NFHS is a well-designed, comprehensive survey that calculates sample size using probability proportion to size. However, inevitable systematic errors and disturbances during data collection due to the pandemic could have also fuelled the ratio. More females also appeared because the survey was conducted around the COVID-19 period and in two phases (pre-pandemic and second wave).

Also, one cannot rule out more males getting infected and succumbing to COVID-19. Men tend to migrate and go out more than women for work, and hence, the chances of getting infected increase. A considerable number of men also lost their lives while returning to their native place during the first phase of the pandemic.
Lastly, NFHS-5 shows that the child sex ratio is still low in Goa 838, Himachal Pradesh 875 and and Telangana 894. Alternatively, some states and UTs have also shown a decline in overall sex ratio from NFHS-4 to 5 viz Andaman and Nicobar, Himachal Pradesh, Jammu and Kashmir, Ladakh, Chhattisgarh and Chandigarh.
The map shows States with lower overall sex ratios are Arunachal Pradesh, Gujarat, Haryana, Jammu & Kashmir, Maharashtra, Madhya Pradesh, and Punjab. This univocal pattern compels us to conclude that while there has been a specific increase, the magnitude nevertheless is highly questionable.
Hence, considering the various possibilities, there is still time and a lot to be done before settling and celebrating the increase in numbers. The accurate picture can only be shown by the upcoming Census of 2022 because undoubtedly, it is the biggest, most dependable, and complete population enumeration for any country.

Very thoughtful and well-written article.
However, unsure of the reliability of the news sources, I came across a few where it was stated that the Census is India, 2021 is cancelled and the next census in India would be conducted in 2031. Do you think, we may not have access to a complete data of the Indian demography for another 10-12 years?

Plastic burning in homes threatens food, water and air across Global South: Study

By Jag Jivan In a groundbreaking study spanning 26 countries across the Global South , researchers have uncovered the widespread and concerning practice of households burning plastic waste as a fuel for cooking, heating, and other domestic needs. The research, published in Nature Communications , reveals that this hazardous method of managing both waste and energy poverty is driven by systemic failures in municipal services and the unaffordability of clean alternatives, posing severe risks to human health and the environment.

From protest to proof: Why civil society must rethink environmental resistance

By Shankar Sharma* As concerned environmentalists and informed citizens, many of us share deep unease about the way environmental governance in our country is being managed—or mismanaged. Our complaints range across sectors and regions, and most of them are legitimate. Yet a hard question confronts us: are complaints, by themselves, effective? Experience suggests they are not.

Economic superpower’s social failure? Inequality, malnutrition and crisis of India's democracy

By Vikas Meshram India may be celebrated as one of the world’s fastest-growing economies, but a closer look at who benefits from that growth tells a starkly different story. The recently released World Inequality Report 2026 lays bare a country sharply divided by wealth, privilege and power. According to the report, nearly 65 percent of India’s total wealth is owned by the richest 10 percent of its population, while the bottom half of the country controls barely 6.4 percent. The top one percent—around 14 million people—holds more than 40 percent, the highest concentration since 1961. Meanwhile, the female labour force participation rate is a dismal 15.7 percent.

From colonial mercantilism to Hindutva: New book on the making of power in Gujarat

By Rajiv Shah Professor Ghanshyam Shah ’s latest book, “ Caste-Class Hegemony and State Power: A Study of Gujarat Politics ”, published by Routledge , is penned by one of Gujarat ’s most respected chroniclers, drawing on decades of fieldwork in the state. It seeks to dissect how caste and class factors overlap to perpetuate the hegemony of upper strata in an ostensibly democratic polity. The book probes the dominance of two main political parties in Gujarat—the Indian National Congress and the BJP—arguing that both have sustained capitalist growth while reinforcing Brahmanic hierarchies.

Urgent need to study cause of large number of natural deaths in Gulf countries

By Venkatesh Nayak* According to data tabled in Parliament in April 2018, there are 87.76 lakh (8.77 million) Indians in six Gulf countries, namely Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates (UAE). While replying to an Unstarred Question (#6091) raised in the Lok Sabha, the Union Minister of State for External Affairs said, during the first half of this financial year alone (between April-September 2018), blue-collared Indian workers in these countries had remitted USD 33.47 Billion back home. Not much is known about the human cost of such earnings which swell up the country’s forex reserves quietly. My recent RTI intervention and research of proceedings in Parliament has revealed that between 2012 and mid-2018 more than 24,570 Indian Workers died in these Gulf countries. This works out to an average of more than 10 deaths per day. For every US$ 1 Billion they remitted to India during the same period there were at least 117 deaths of Indian Workers in Gulf ...

Counterview Desk India’s civil society network, National Alliance of People’s Movements (NAPM)* has said that the controversial transgender Bill, passed in the Rajya Sabha on November 26, which happened to be the 70th anniversary of the Indian Constitution, is a reflection on the way the Government of India looks at the marginalized community with utter contempt.
