Top 10 countries with the biggest population decline percent: Europe leads, with only one from Asia

The global population has seen extraordinary growth in recent centuries, defying initial expectations. While it was expected to take hundreds of thousands of years to reach 1 billion people, the population surged to seven times that figure within just 200 years.
By 2011, the world's population had hit 7 billion, and projections from the United Nations indicate that this upward trend will continue in the decades ahead, estimating a rise of 8.6 billion in 2030, 9.8 billion in 2050 and 11.2 billion in 2100.
However, geopolitical conflicts can also shake up a country's population as a result of refugees and the unfortunate loss of lives, like Ukraine has been identified as the fastest-shrinking country in the world, driven by the ongoing conflict between Russia and Ukraine.
Europe is witnessing a significant population decrease, with a reported shrinkage of 0.2% in 2023 compared to the previous year, with six of the world's top ten countries in the region.
In addition to declining birth rates and increasing aged populations, which were further catalysed by the Greek financial crisis of the 2010s, Greece's population of around 10 million is expected to lose 1 million by 2050.
Mass emigration in Tuvalu, a country of just 10,000 people in Oceania, the second-fastest shrinking globally, will take a hit, making it one of the first places on Earth to disappear due to a changing climate and rising ocean levels.
On the contrary, Asia is one of the most populated continents, experiencing an overall growth rate of 0.6% as of 2023, with countries like India leading and being the most populated globally.
Rounding up the top ten, Japan is the only Asian nation recognised for its significant population decline, driven by its burgeoning elderly population, declining birth rates, and the tendency to marry young and have children later.

Note: Due to outmigration and demographic change. The sharp population decline in Ukraine is largely attributed to refugees fleeing due to the war.

Despite Clashes With US Presidents, Netanyahu Usually Gets His Way

Jerusalem: A little over a month ago, Prime Minister Benjamin Netanyahu appeared to have been shunted to the shadows by US President Donald Trump, who hopscotched the Middle East without visiting Israel, traditionally Washington's closest regional ally. Worse still, from Netanyahu's perspective, Trump lifted sanctions on neighbouring Syria - something Israel opposed - and talked up the prospects of securing a nuclear deal with Iran, something the prime minister has always cautioned against. Fast forward five weeks and the United States has bombed Iran's main nuclear installations, fulfilling a decades-old dream of Netanyahu to convince Washington to bring its full military might to thwart Tehran's atomic ambitions. The US attack underscores a broader truth that has defined Netanyahu's career: no matter how fraught his relationships with successive presidents, he normally ends up getting what he wants. For over three decades, Netanyahu has clashed - often spectacularly - with American leaders. He has lectured them, defied them, embarrassed them publicly and privately. And yet, across Democratic and Republican administrations, US military aid has flowed largely uninterrupted to Israel. Washington remains Israel's chief arms supplier and diplomatic shield. "He probably has concluded that he always gets away with it," said a senior United Nations official in Jerusalem who declined to be named. "It's hard to argue otherwise." Just one month ago, opposition leader Yair Lapid accused Netanyahu of destroying Israel's relations with the United States. This weekend's action represents the closest US-Israeli military alignment yet against a common adversary. Withstanding Pressure Netanyahu's belief in his ability to advance his agenda, and withstand American pressure when needed, has deep roots. Barely a month after becoming prime minister for the first time in 1996, he met President Bill Clinton in Washington and immediately rubbed him up the wrong way. "Who the f--- does he think he is? Who's the f---ing superpower here?" Clinton asked his aides afterwards, according to US diplomat Aaron David Miller, who was present. But vital US aid to Israel continued to flow - something that would remain a constant over the years. Netanyahu was voted out of office in a 1999 election and did not return to power until a decade later, by which time Barack Obama, a Democrat like Clinton, was in the White House. Relations between the two turned openly hostile, initially over Israeli settlement building in occupied territory that Palestinians claim for a future stake - a constant thorn in US-Israeli relations. Matters deteriorated further as Obama entered negotiations with Iran to curb its nuclear drive - a project that Israel said is aimed at creating atomic bombs and that Tehran has said is for purely civilian purposes. Netanyahu spoke to Congress in 2015 at the invitation of Republicans to denounce the prospective deal, without informing the White House. "(The accord) doesn't block Iran's path to the bomb; it paves Iran's path to the bomb," he said. Obama was widely reported to have been furious, but still, the following year Washington delivered the largest military aid package to Israel in US history - $38 billion over 10 years. Political analysts say Netanyahu takes US support as a given, confident that backing from evangelical Christians and the small Jewish-American community will guarantee that Israel remains well-armed, however much he antagonises the White House. Convincing Trump When Hamas militants launched a surprise attack on Israel in October 2023, then-President Joe Biden flew to Israel to show his support, authorising a huge flow of weapons to help with the conflict unleashed in Gaza. But relations between Netanyahu, a right-winger, and Biden, a Democrat, deteriorated rapidly, as Washington grew alarmed by the spiralling number of civilian deaths and the burgeoning humanitarian crisis in the Palestinian enclave. Biden held back on some heavy munitions deliveries and imposed sanctions on a number of violent Israeli settlers, so his defeat at the hands of Trump in last November's presidential election was celebrated by Netanyahu. Finally, he had a Republican in office at a crucial moment for Israel. However, things did not go smoothly, at least to start with. Like Biden before him, Trump was unhappy at the protracted conflict in Gaza and then he blindsided Netanyahu during a meeting on April 7, when he revealed that he was launching direct talks with Tehran aimed at finding a diplomatic solution to the protracted nuclear stand-off with Iran. But while Trump publicly positioned himself as a peacemaker, Netanyahu consistently pushed for military intervention. Although it is unclear if Netanyahu ever got him to say "yes" to Israel's war plans, it was at least not a "no", according to two senior US officials and a senior Israeli source. As soon as Israel launched its aerial war on Iran in the early hours of June 13, Israel pushed the United States to join in, urging Trump to be on the winning side of history, two Israeli officials said last week. "Mr President, Finish the job!" read large billboards that have popped up in Tel Aviv. The sense of relief when the US bombers struck Iran's most protected nuclear sites on Sunday was palpable. "Congratulations, President Trump. Your bold decision to target Iran's nuclear facilities with the awesome and righteous might of the United States will change history," Netanyahu said in a brief video address. "May God bless our unshakeable alliance, our unbreakable faith," he concluded.

Markets may dip as US strikes on Iran stoke oil fears, global volatility

Indian markets may open lower on Monday due to fears of crude oil disruption from the West Asia though domestic institutional investors may support valuations Sundar Sethuraman Mumbai Listen to This Article Investors may have to brace for a spike in volatility on Monday following the US military's direct involvement in the Israel–Iran conflict over the weekend. Experts believe benchmark Sensex and Nifty may correct 1–1.5 per cent if oil prices surge and Asian markets fall due to the widening of the West Asia conflict. However, domestic institutional investor (DII) buying could cushion the fall. Last week, the domestic markets had gained over 1.5 per cent even as hostilities between Iran and Israel escalated. On Saturday, President Donald Trump announced targeted strikes on three of Iran's key nuclear facilities—Fordow, Natanz, and Isfahan—using

Iran-Israel war & US bombings: Should possible Strait of Hormuz closure worry India about its oil supply? Explained in 10 points

India's reliance on crude oil imports is at approximately 90%, with Middle Eastern nations supplying more than 40% of these imports. (AI image) Iran-Israel war & Strait of Hormuz: With escalating tensions between Iran and Israel, especially after the US bombed nuclear facilities in Iran earlier today, there are rising fears of the Strait of Hormuz being closed. The Strait of Hormuz is a crucial maritime passage handling 20% of global oil and gas transportation. According to state-run media, Iran's Parliament has approved the closure of Strait of Hormuz and the final decision will be taken by Iran's Supreme National Security Council. What will be the impact of the potential closure of the Strait of Hormuz? And importantly, how will India be hit? We take a look: Why is the Strait of Hormuz important? The Strait of Hormuz serves as a crucial maritime connection between the Persian Gulf and the Arabian Sea, extending into the Indian Ocean. This vital waterway, with its narrowest section at just 21 miles (33 kilometres), has Iran to the north and the Arabian Peninsula to the south. The navigable channels are considerably restricted, extending only two miles in either direction, which creates vulnerability to potential blockades and hostile actions. The Strait of Hormuz holds immense strategic and economic significance, particularly as a mandatory route for oil vessels departing from Persian Gulf ports. This maritime passage facilitates the transportation of one-fifth of global oil and gas supplies. Statistics from the US Energy Information Administration (EIA) indicate that in 2024, the daily transport volume reached 20.3 million barrels of oil and 290 million cubic metres of LNG. The major oil-producing nations of the region - Saudi Arabia, Iraq, UAE, Qatar, Iran, and Kuwait - rely on this passage for their exports. Whilst historical concerns about disruptions to Persian Gulf energy flows majorly affected Western nations, particularly the US and Europe, in today's situation the implications would most significantly impact China and Asian countries. Based on EIA data quoted by PTI, Asian nations received 8% of crude oil and condensate shipments through the Strait of Hormuz in 2022. India, China, Japan, and South Korea collectively made up 67% of total flows during 2022 and the firstl six months of 2023. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Cuối cùng, chơi miễn phí game chiến thuật hay nhất 2025! Sea of Conquest Phát ngay Undo Also Read | 'Highest in two years': India increases oil imports from Russia, US amidst Iran-Israel war; why it's about strategic positioning, not panic India's reliance on crude oil imports is at approximately 90%, with Middle Eastern nations, whose exports pass through the Strait of Hormuz, supplying more than 40% of these imports. EIA reports indicate that during the first quarter of 2025, China's crude imports via the Strait of Hormuz reached 5.4 million bpd. India received 2.1 million bpd, whilst South Korea and Japan imported 1.7 million bpd and 1.6 million bpd respectively. The IEA has emphasised that any interference with the flow through the Strait would significantly impact global oil markets. How will the closure of Strait of Hormuz impact India? India imports 5.5 million barrels per day (bpd) of crude oil, with 2 million bpd passing through this strategic waterway. However, experts suggest that India's position remains secure due to its diversified import strategy, with alternative suppliers including Russia, the United States and Brazil available to maintain supply continuity. The Russian oil supply remains unaffected by Hormuz-related disruptions, as it uses alternative routes including the Suez Canal, Cape of Good Hope, or Pacific Ocean pathways. Similarly, supplies from the US, West Africa, and Latin America, though more expensive, serve as viable alternatives. Regarding gas supplies, India's primary supplier Qatar delivers without using the Strait of Hormuz for Indian shipments. Additional LNG sources from Australia, Russia and the US remain accessible regardless of any Strait of Hormuz closure . However, analysts predict that increasing tensions in this significant energy supply region could cause short-term price fluctuations, potentially pushing oil prices towards $80 per barrel. India relies on imports for 90% of its crude oil requirements and sources approximately half of its natural gas from international markets. The imported crude oil undergoes refining to produce petrol and diesel, while natural gas serves multiple purposes including power generation, fertiliser production, CNG for vehicles, and domestic cooking gas supply. India obtains approximately 40% of its oil requirements from Middle Eastern countries including Iraq, Saudi Arabia, the United Arab Emirates, and Kuwait, with shipments travelling through the Strait of Hormuz. Russia has become a significant oil supplier to India, with current imports exceeding the total imports from Middle Eastern nations. According to preliminary trade data from Kpler, Indian refineries imported 2-2.2 million bpd of Russian crude oil in June, surpassing the combined imports of about 2 million bpd from Iraq, Saudi Arabia, the UAE and Kuwait, marking the highest level in two years. Additionally, imports from the United States increased to 439,000 bpd in June, showing substantial growth from 280,000 bpd in the previous month. Although current supplies remain stable, vessel movements indicate a reduction in crude loadings from the Middle East in the forthcoming period. Vessel operators are showing reluctance to dispatch empty tankers (ballasters) to the Gulf, with numbers decreasing from 69 to 40, whilst MEG-bound signals from the Gulf of Oman have reduced by half. Kpler reports quoted by PTI indicate potential tightening of MEG supplies in the immediate future, possibly necessitating adjustments to India's procurement strategy, noting significant changes in India's import patterns over the past two years. In the event of escalating tensions or temporary Hormuz disruptions, Russian oil supplies could increase, providing both availability and cost advantages. India has options to diversify its oil imports from the United States, Nigeria, Angola, and Brazil, despite higher transportation expenses. On June 13, Oil Minister Hardeep Singh Puri confirmed India's sufficient energy reserves for upcoming months, with capability to access alternative sources if needed. India can utilise its strategic petroleum reserves, which cover 9-10 days of imports, to manage any supply gaps. To control inflation during price surges, particularly for diesel and LPG, the government maintains the option of implementing price subsidies. Will oil prices rise? Global oil prices saw a sharp increase after Israel launched attacks targeting Iranian military commanders, homes, military installations and nuclear facilities on June 13. Iran retaliated by firing numerous ballistic missiles. This heightened tension caused oil prices to rise substantially, as concerns grew about geopolitical instability and potential supply chain disruptions. The benchmark Brent crude oil has reached $77 per barrel, marking a 10 per cent increase since the onset of hostilities. According to oil market specialists at Goldman Sachs, prices could potentially rise beyond $90 should the situation deteriorate further. Citigroup analysts project that Brent crude values might approach $90 per barrel in the event of a closure of the Strait of Hormuz. The credit rating organisation Icra indicated that any intensification of regional tensions could have considerable effects on oil prices. Higher oil prices would reduce the profits that state-owned retailers IOC, BPCL and HPCL have built up by maintaining stable retail prices despite previous decreases in international rates. Also Read | Iran-Israel conflict: India keeping tab on Chabahar Port, International North-South Transport Corridor; why it's important According to Jain of Yes Securities, oil markets remain adequately supplied, supported by OPEC's 4 million barrels per day spare capacity and a pre-conflict global surplus of 0.9 million bpd. Additional stability comes from US shale production. Global security analysts deem an extended blockage of the Strait of Hormuz unlikely, given the US naval forces in the region. Any such action by Iran would not only impact the oil exports of Saudi Arabia, the UAE, Kuwait and Qatar but would also hamper its own export capabilities. Despite aggressive rhetoric from Iranian conservatives and state media predictions of oil prices reaching $400 per barrel, the international trade analysis organisation Kpler suggests the probability of a complete blockade remains minimal, citing significant deterrents for Iran. Such an action would severely affect China, Iran's primary oil buyer, which sources 47 per cent of its maritime crude imports from the Middle East Gulf region. As the world's second-largest economy, China stands as the principal purchaser of Iranian oil, reportedly consuming more than three-quarters of Iran's oil exports. The fact that Iran relies heavily on the Strait of Hormuz for its oil shipments through Kharg Island, which manages 96% of its exports, makes any self-imposed blockade counterproductive to its interests.
