# Mega Cities World Hubs in 2025 By Bianca | Published 2008-03-21 | World Source: Trend Hunter, https://www.trendhunter.com/trends/mega-cities-2025 References: [forbes](http://www.forbes.com/2008/03/19/cities-population-pollution-innovation08-cx_tvr_0319futurecities.html?partner=globalnews_newsletter) The globe is expanding rapidly, and as it does, more mega cities (populations of 8 million+) are beginning to develop. People are drawn to city cores because, unless their business is online, the majority of jobs are found in these populated hubs. The [World Resource Institute](https://www.trendhunter.com/trends/codiagnostics) thinks that by 2025, the world will have around 33 mega cities. Particularly in Asia, the need for bigger city centers has spurred plans for mass expansion. "The number of urban dwellers is expected to hit 5 billion globally by 2025--double the number of 1990" according to [Forbes Magazine's](https://www.trendhunter.com/trends/the-setai-miami-beach) article which listed the 10 Biggest Cities of 2025. Even if telecommuting becomes bigger in the future, there is no doubt people will continue to inhabit city cores. People have a natural affinity for social interaction, a need built into our nature. Real life social interaction won't be replaced by social networking and teleconferencing, it will only make the desire to connect face to face stronger. "Asia and Latin America, each cluttered with rural workers looking for better jobs and housing in the city, are slated to have nine of the world's 10 most populous cities by 2025," Forbes explains, listing specifics like Mumbai, Calcutta, Delhi, Karachi, Shanghai, Mexico City and Sao Paulo. "New York and Tokyo are the only traditional power cities expected to remain on the mega cities list in 17 years," Forbes adds. **Tokyo**, which is now at a population of 35.2 million is project to hit 36.4 million by 2025. **Mumbai** will jump from 18.2 million today to 26.4 million; **Delhi** from 15 million to 22.5 million; **Dhaka** from 11.9 million to 22 million; **Sao Paolo** from 18.3 million to 2.4 million; **Mexico City** from 19.2 million to 21 million; **New York** from 18.7 million to 20.6 million; **Calcutta** from 14.7 million to 20.6 million; **Shanghai** from 14.5 million to 19.4 million; **Karachi** from 11.6 million to 19.1 million The images in the gallery are from the Forbes article. ## Trend Insights (Trend Hunter) - Score: 2.1/10 - Popularity: 42% | Activity: 14% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [World](https://www.trendhunter.com/world) > [Travel](https://www.trendhunter.com/travel) ## Key Themes ### What Makes This Trend Stand Out - **Rapid Urbanization:** The expansion of mega cities indicates a trend of rapid urbanization globally, creating opportunities for infrastructure development and urban services innovation. - **Increased Job Opportunities:** The growth of mega cities leads to an increase in job opportunities in various industries, presenting a chance for businesses to tap into emerging markets and cater to urban workforce demands. - **Urban Socialization:** As mega cities thrive, the need for social interaction and community building becomes crucial, creating opportunities for businesses to provide innovative solutions that foster connection and engagement among urban dwellers. ### Sectors Adopting This - **Urban Infrastructure:** The expansion of mega cities calls for disruptive innovation in urban infrastructure, including transportation, housing, and utilities, to accommodate the growing population and enhance quality of life. - **Technology and Telecommunications:** As telecommuting becomes more prevalent, businesses in the technology and communications sectors have an opportunity to develop innovative solutions that support remote work, connectivity, and efficient communication within mega cities. - **Hospitality and Entertainment:** With the need for social interaction and community building in mega cities, there is potential for disruptive innovation in the hospitality and entertainment industries, such as creating unique experiences, co-working spaces, and communal gathering places. ## Related on Trend Hunter - [City-Building Game Sequels](https://www.trendhunter.com/trends/cities-skylines-ii.md) - [Bridge-Defining Tranquil Cities](https://www.trendhunter.com/trends/mindfulness-city.md) - [Streamlined Airport Metro Hubs](https://www.trendhunter.com/trends/metro-transit-center-station.md) - [Experimental Urban City Developments](https://www.trendhunter.com/trends/woven-city.md) - [Cube-Shaped Skyscraper Buildings](https://www.trendhunter.com/trends/mukaab.md) - [Expansive Creative Regional Festivals](https://www.trendhunter.com/trends/tokyo-creative-salon.md) - [Entrepreneur-Specific Global Hubs](https://www.trendhunter.com/trends/global-hub.md) - [Dynamic Modern Football Stadiums](https://www.trendhunter.com/trends/manchester-united-3.md) - [Newly Built Mindfulness Cities](https://www.trendhunter.com/trends/gelephu-mindfulness-city.md)
