Throughout human history, reaching the age of 100 was considered an exceptional accomplishment. However, in recent decades, the number of centenarians in the world has been on the rise.
The increases in longevity for both men and women are welcomed developments. This remarkable accomplishment in human longevity, reaching 100 years or more, also poses challenges for the long-living individuals, their families, communities, and societies.
The rise in the number of centenarians can be attributed to a number of key economic, social, and scientific factors. These factors encompass public health initiatives, sanitation, environmental enhancements, medical advancements, improved access to healthcare, enhanced nutrition, medical treatments, vaccines, antibiotics, decline in infectious diseases, higher living standards, education, better management of chronic conditions, preventive care, social connections, and lifestyle choices.
In 1950, there were nearly 15,000 centenarians worldwide, representing a very small fraction of one percent of the global population of 2.5 billion. By 2026, the number of centenarians had increased by 45 times, reaching 672,000. This figure continued to represent a small, but larger fraction of one percent of the world’s current population, which had tripled to 8.3 billion.
The number of centenarians is expected to continue rising. It is projected that by 2050, the number of centenarians will almost quadruple, increasing from today’s 672,000 to 2.6 million. Furthermore, by the end of the century, the number of centenarians is expected to be approximately twenty-seven times greater than it is today, reaching 18 million by 2100 (Figure 1).

Of the world’s 672,000 centenarians, nearly two-thirds reside in the more developed regions. The country with the largest number of centenarians is Japan with 126,000, accounting for nearly one-fifth of the world’s total. Following Japan, the next four countries and their number of centenarians are the United States (77,000), China (53,000), India (43,000), and France (35,000) (Table 1).

In these various countries, the large majority of centenarians are women. For example, in Japan, women make up nearly 90% of centenarians. Similarly in the United States, nearly 80% of the centenarians in 2024 were women.
The oldest, documented centenarian to have ever lived is Jeanne Calment of France. She died at the age of 122 years and 164 days. Her age is verified through reliable birth, marriage, and death records in Arles, France, with her life spanning from 1875 to 1997. Calment’s father lived to the age of 94 and her mother lived to the age of 86.
The longest-lived man in recorded history was Jiroemon Kimura of Japan who died at the age of 116 years and 54 days. He was born in 1897 and died in 2013, making him the only man in history confirmed to have reached the age of 116. Kimura credited his longevity to living an active life and practicing the concept of hara hachi bunme in Japan, which involves eating until he was only 80% full.
Healthy aging and increased longevity in both men and women are influenced by a combination of genetic and non-genetic factors. In addition to genetics, major contributors to long life include access to healthcare, a healthy and nutritious diet, regular physical activity, not smoking, moderate alcohol consumption, maintaining a healthy body weight, strong social connections, managing stress and chronic conditions, getting sufficient quality sleep, maintaining a sense of purpose, and engaging in vigorous exercise (Table 2).

Medical research is continuing to explore ways to extend healthy lifespan and increase human longevity. Some of this research is focused on anti-ageing interventions, which include targeting biological mechanisms of ageing, delaying the onset of chronic diseases, and prolonging the period of healthy life. These interventions aim to enable individuals to live long enough to become centenarians. Unlike in the past, centenarians are no longer exceptional societal outliers. This significant change in human longevity is impacting not only centenarians but also reshaping the ways individuals, families, communities, and societies approach aging, retirement, and healthcare
Some believe that advancements in medicine and biotechnology may further promote the increase in human longevity. However, others argue that humanity has reached an upper limit of longevity, with the maximum reported age at death plateauing at around 115 to 122 years.
Unlike in the past, centenarians are no longer exceptional societal outliers. This significant change in human longevity is impacting not only centenarians but also reshaping the ways individuals, families, communities, and societies approach aging, retirement, and healthcare.
Living to 100 years or more is a goal that many people aspire to achieve. The rising number of centenarians and older individuals raises important questions and issues, such as retirement ages, healthcare, pensions, living expenses, and elder care.
To reach the age of 100 or beyond, long-term planning, including advance care planning, is crucial for individuals, families, and governments. This planning essentially involves ensuring that there are enough resources available for pensions, healthcare, living expenses, and elder care needs.
Unfortunately, individuals, families, and governments tend to neglect long-term planning. As a result, the gaps between retirement funds and the expenses for individuals living longer lives are significant and increasing.
Most older individuals have limited savings, a financial shortfall that is becoming increasingly common among older women and men. This issue is exacerbated by the demographic ageing of populations, with decreasing numbers of people in the workforce able to contribute to pensions and healthcare for retirees.
These financial gaps are not only causing economic challenges for older individuals and families, but also leading to a reevaluation of government policies and programs related to retirement ages, pension benefits, and health care for seniors.
In conclusion, the increase in human longevity and the rise in the number of centenarians are positive trends. However, they also bring about significant challenges for older individuals, communities, and societies.

KARACHI, Pakistan, May 5 2026 (IPS)
“We’ve abandoned this couple completely; we have not done even 1% of what they did for us all these years!” said journalist Asad Ali Toor.
Arrested on January 23, 2026, two lawyers, also husband and wife – Imaan Mazari and Hadi Ali Chatha – were sentenced the next day to 17 years under the Prevention of Electronic Crimes Act (PECA), 2016 (amended in 2025) – a law Mazari had described as even more ‘draconian’ than its original version. Fines of Rs36 million (USD129,261) each were also imposed on the two under Sections 9 (glorification of an offence), 10 (cyber terrorism), and 26-A (false and fake information) under the same law.
“They have not violated PECA, and in my opinion the prosecution failed to prove any of the ingredients of any offence under the law,” said human rights activist and lawyer Jibran Nasir. He added that “the military elite and the new chief justice in the Islamabad High Court have taken a personal dislike to Imaan and Hadi. He noted that “The laws may be inherently flawed, even draconian, but more dangerous is their malicious application by the state.”
The amendments on PECA were pushed through parliament within a week, without debate, and signed into law by President Asif Ali Zardari. The move triggered nationwide protests by journalists and rights groups, who warned that the law lacked safeguards. The government, however, defended it as necessary to regulate social media, arguing that similar frameworks exist globally.
Charges, Judgment and Allegations
The judgment stated that Mazari was accused of “disseminating and propagating narratives that align with hostile terrorist groups and proscribed organisations”, while Chatha was charged with reposting her content. The police report also alleged her social media content portrayed the armed forces as ineffective against groups such as the Balochistan Liberation Army (BLA) and Tehreek-i-Taliban Pakistan.

For Toor, who runs the YouTube channel Asad Toor Uncensored, the case is deeply personal. In 2024, he spent 20 days in Federal Investigation Agency custody and 12 in solitary confinement at Rawalpindi’s Adiala Jail, the same prison where the couple is now held.
Arrested on February 26, 2024, on “digital terrorism” charges linked to his coverage, among other things, of a Supreme Court ruling stripping the Pakistan Tehreek-e-Insaf of its election symbol, he was granted bail on March 17, 2024.
He credits Mazari and Chatha with securing his release. “They argued that journalists should not face criminal charges for “honest criticism” of court judgments, citing then Chief Justice of Pakistan Qazi Faez Isa and Attorney General for Pakistan Mansoor Usman Awan.”
But journalists like Toor are not alone in feeling what he describes as “a certain vacuum.”

‘It Feels Like I’ve Lost My Right Arm’
The two lawyers had built a reputation for taking on cases few lawyers would touch.
“Imaan and Hadi have always taken up cases most lawyers shy away from due to their controversial or dangerous nature — including blasphemy accusations, enforced disappearances, and press freedom cases — often representing the most marginalised people, without charging anything,” said rights activist Usama Khilji, director of Bolo Bhi, an advocacy forum for digital rights.
“It feels like I’ve lost my right arm,” said a woman, who requested anonymity, as she struggles to secure the release of her brother and more than 400 others accused of blasphemy, languishing in jail across Pakistan.
“In the past three years, I have met countless lawyers and even judges, but no one fought like Imaan. She missed nothing – every detail mattered; she was relentless,” said the woman, talking to IPS.
Leading the campaign, she said most of the accused came from poor backgrounds. “She didn’t even charge for the photocopying of documents submitted to the court – she paid out of her own pocket.”

The sense of loss extends well beyond individual cases.
Rahat Mehmood, mother of missing poet and writer Mudassir Naru, who disappeared in 2018 described the couple’s arrest as devastating.
“It’s like my support system has collapsed,” she said over the phone from Faisalabad. “Not just for me—these two were a ray of hope, an anchor for hundreds of mothers, especially Baloch mothers.”
Mazari’s work, she said, was not limited to legal representation.
Her grandson, Sachal, was just six months old when his father was taken and later lost his mother in 2021. Court hearings, Mehmood recalled, became rare moments of relief. “They played hide-and-seek, raced around, and she would bring him toys and candy. Tell me—who does that?”
Although her son’s case has not been heard in over a year, Mehmood said that, with Mazari by their side, they had always had hope. “But now,” she added, “it’s all darkness.”

Mazari’s advocacy extended beyond the courtroom. She appeared in two of the three press conferences held by families of the blasphemy accused, which drew “huge crowds and media attention”. Today, more than 120 people are out on bail. “It’s because of the efforts of these two,” said the sister of the accused.
Their absence is being felt acutely among many others with the least protection.
A week after the lawyers’ arrest, Rana Shahbaz, a street vendor, went to visit Mazari in jail but was turned away. “I was told by jail authorities no one was allowed to meet her.” He had brought dry fruits, juices and clothes, which authorities refused to accept.
Shahbaz, president of the Anjuman Rehri Baan, Islamabad (association of street vendors), which represents over 20,000 street vendors, said Mazari had been instrumental in securing relief for them. Despite holding licences from the Metropolitan Corporation Islamabad, they routinely face raids and eviction by city administrations.
“Last year because of Madam Imaan, the Islamabad High Court stopped authorities from removing our stalls. She presented video evidence showing stalls being dismantled despite having permits,” Shahbaz said.
Since their arrest, he added, the pressure has returned.
“The day they were arrested, an official told us, ‘Call your lawyers now — I’ll see who stops me.’ She was right — only Madam Imaan had the courage to stand up for us,” said Shahbaz, whose stall has been destroyed thrice in the past two years.
“It costs Rs150,000 (USD 538) to set up these makeshift stalls – financed through a bank loan with a monthly instalment of Rs7,000 ($25). Each time authorities dismantle them, repairs cost up to Rs40,000 (US$144), making it impossible to keep up with repayments and pushing me toward default,” he said. Last week, despite having a valid licence, his lassi (yoghurt drink) and fresh milk stall were demolished.
The pretext for crackdowns can be anything—from late-night vending to fines for not displaying price lists or even refusing to offer “freebies” to the police. “Madam Imaan knew well that vendors are exempt from the curfew time for regular shops or that we can only display the price list once it comes from the city authorities and it doesn’t until midday,” he pointed out.
Like many others, Shahbaz said, the two lawyers worked for vendors for free. “We didn’t even know what the basic legal processes cost,” he said.
Muted Response
Despite the breadth of their work, support beyond affected communities has been limited.
“I hold both the journalist and legal fraternities responsible for doing virtually nothing,” said Toor. “Individual voices may struggle, but unions and bar councils have the power to pressure the government.”
Toor’s assessment is shared by lawyer Nasir. He acknowledged that the legal fraternity, with “many lawyers, like judges, appear to be motivated by self-preservation as opposed to the preservation of the constitutional and fundamental freedoms” and which has “blunted its effectiveness” and left it “equally vulnerable” in the long run.
Yet, even as this institutional weakness is laid bare, others frame the duo’s actions less as miscalculation and more as conscious defiance. Media development expert Adnan Rehmat argued that while some may see them as having paid a heavy price for their stance, the two have a long history of public-interest resistance. “They consciously chose to risk themselves to highlight state abuses, and their courage should be lauded—and we must continue raising our voices in their favour.”
As a result, sporadic protests have failed to shift the situation. With public pressure waning, the battle has moved to the courts.
An Uncertain Path
But even there, justice has remained elusive.
The Islamabad High Court refused interim relief. “Everyone knows the 17-year sentence is the product of a sham trial. No superior court in any modern judicial system would uphold it,” said senior advocate Faisal Siddiqi, the lawyer representing them.
Undeterred, the defence has moved the Supreme Court of Pakistan after the IHC failed to fix an early hearing for nearly two months – a delay which Siddiqui called “unheard of” and a ploy to “deny Imaan and Hadi their deserved liberty”.
The bail petition has since been accepted by the Supreme Court, offering a glimmer of hope. “It is our only and last hope,” said Siddiqi.
One hundred days on, that hope remains uncertain.
What is clearer, however, is the void left behind – felt in courtrooms, in protest spaces, and in the lives of those who had come to rely on the two lawyers willing to take risks few others would.
For many, it is not just their absence that is being measured in days but also the growing silence it has left behind.
“I cannot fathom why people like Imaan and Hadi are being punished—and for what,” said Mehmood. “They deserve to be saluted, not jailed!”

Africa is on the frontlines of the climate crisis, warming faster than the global average and facing disproportionate climate impacts, despite contributing the least to global greenhouse gas emissions.
This is particularly evident in the growing pressures that climate change is placing on water resources and systems across the continent. As water underpins agriculture, livelihoods, ecosystems, and energy production, water-related climate impacts are deepening inequalities and threatening sustainable development across Africa.
At the forefront of this year’s ECOSOC Youth Forum – the largest annual UN gathering of young people – four African climate youth leaders led a dynamic discussion spotlighting the key role that African youth play in driving climate solutions across the continent, building community resilience, strengthening water security, and advancing locally led adaptation efforts.
Their insights highlighted how young people are not only responding to the climate crisis but reshaping the development agenda through innovation, advocacy, and community rooted action.
African youth are charting bold new pathways for climate leadership and proving that the future of climate action is being shaped by their vision and determination.
