Southern Asia recorded the largest net migration loss in Asia, while Western Asia remained the region’s strongest migration destination, according to migration data compiled from the UN Population Division and international migration studies .

A visual analysis published by Seasia Stats and World Visualized showed Southern Asia posting a net migration balance of -2.2 million people over a five-year average period, far exceeding outflows recorded in Eastern, South-Eastern and Central Asia .

Western Asia stood out as the only Asian subregion with positive net migration, recording a net gain of approximately 434,000 people.

Net migration measures the difference between immigrants entering a region and emigrants leaving it.

Migration experts say Western Asia’s positive migration trend is largely driven by Gulf economies, including Saudi Arabia, the United Arab Emirates, Qatar and Kuwait, which rely heavily on foreign labour across construction, healthcare, domestic work and technology sectors.

The World Bank and the International Organisation for Migration have repeatedly identified the Gulf region as one of the world’s largest migrant worker destinations due to higher wages and strong labour demand.

Large migrant populations from India, Pakistan, Bangladesh, Nepal and the Philippines continue moving to the Gulf in search of economic opportunities.

Southern Asia’s large negative migration balance reflects longstanding outward migration patterns from countries such as India, Pakistan, Bangladesh and Nepal.

Economic opportunity, overseas employment, education and family reunification remain among the biggest drivers of migration from the region, according to UNESCO and UN migration reports.

India alone has one of the world’s largest overseas diasporas, with millions of citizens living and working abroad.

Eastern Asia and South-Eastern Asia also recorded net migration losses, though at much smaller levels compared to Southern Asia.

Ageing populations, slowing economic growth and changing labour markets are believed to be reshaping migration trends in countries including China, Japan and South Korea.

Meanwhile, Southeast Asian nations continue experiencing both outbound labour migration and growing urban migration within the region.

The International Organisation for Migration estimates there were more than 281 million international migrants worldwide in recent years, with Asia remaining central to global migration flows.

Large crowds gathered along the marathon route, waving flags and holding signs as runners moved through the city.

“Africa deserves appreciation because all the best athletes in the world are from Africa. So we need to be here every year. Africa is the continent of the marathon,” one participant said.

The race also carried added significance as Cape Town seeks recognition as the first African marathon to join the Abbott World Marathon Majors series.

Cape Town Mayor Geordin Hill-Lewis and race officials attended the event, which organisers described as a final assessment process for inclusion in the elite marathon circuit.

Although much attention focused on Kipchoge’s participation, Ethiopia’s Mohamed Esa won the men’s race with a time of 2 hours, 4 minutes and 55 seconds.

The performance broke the previous course record and became the fastest marathon time recorded on African soil.

Ethiopian runner Yihunilign Adane finished second in 2:04:59, while Kenya’s Kalipus Lomwai came third in 2:05:06.

Kipchoge finished 16th with a time of 2:13:29 after running at a conservative pace.

The Cape Town event marked the opening stage of Kipchoge’s “Eliud’s World Tour,” which will continue in Porto Alegre, Brazil , on July 12 before heading to the Melbourne Marathon in Australia on October 11.

Covering approximately 22,387 kilometres (13,910 miles), the theoretical journey covers 17 countries across Africa, the Middle East, Europe, Central Asia , and Siberia (Brilliant Maps, Beauty of Planet Earth).

According to route simulations, the entire walk would take around 4,492 hours, or over 187 days of continuous walking. Realistically, walking 8 hours per day would stretch the journey to more than 560 days.

The elevation change along the path is estimated at 117,693 metres ascended and 117,686 metres descended. That’s equivalent to climbing Mount Everest 13 times.

Despite being fully mapped and technically walkable, no one is known to have completed the entire route from Cape Town to Magadan. The route is believed to be more theoretical than practical, primarily due to logistical and geopolitical challenges.

The path cuts through regions with visa complexities, conflict zones, and unpredictable terrain and weather conditions , especially in parts of Sudan, Syria, and eastern Russia.

For context, one of the most famous recorded long-distance treks was undertaken by George Meegan, who walked from Tierra del Fuego in South America to Prudhoe Bay, Alaska, a journey that covered 30,608 kilometres over 2,426 days between 1977 and 1983.

Though longer in total distance, his walk did not follow a single mapped road and still falls short of the Cape Town–Magadan route in terms of continuity.
