Asia has undergone one of the most significant urban transformations of the last half-century. Cities that were once mid-sized have expanded into megacity regions, with populations rivaling entire countries.
Today, Asia is home to many of the world’s largest metropolitan areas, from Tokyo and Delhi to Shanghai and Dhaka. While coastal corridors and river basins have become densely built-up, large inland regions remain sparsely urbanized, creating a striking contrast across the continent.
The data for this visualization comes from World Population Review.
Tokyo remains the world’s largest metropolitan area with more than 37 million people, followed closely by Delhi at roughly 35 million. Shanghai, Dhaka, Beijing, and Mumbai all exceed 20 million residents.

Greater Jakarta now forms one of the world’s largest continuous urban regions, home to over 30 million people. This growth reflects decades of migration toward economic hubs in Indonesia.
Similar patterns appear in China’s Pearl River Delta and across major Indian corridors, where neighboring cities have fused into single metropolitan zones. These megaregions highlight a defining feature of modern Asian development: cities expanding outward until they merge with the next.
From Lahore to Dhaka, the Indo-Gangetic Plain has evolved into one of the most densely populated urban corridors on Earth.
Cities like Delhi, Kolkata, Dhaka, and Lahore form a nearly unbroken chain of development supported by fertile land and major river systems. In contrast, mountainous regions such as Tibet, the Himalayas, and Central Asia remain lightly urbanized.

Home prices across North America have surged over the past two decades, driven by population growth, limited housing supply, and post-pandemic demand.
This infographic shows how average home prices have changed from July 2005 to July 2025 across 25 major North American cities, based on Zillow data compiled by Hanif Bayat.
On average, home prices across the top 25 cities in North America have risen by 92%, or nearly doubled, between 2005 and 2025.
The table below shows the North American cities where home prices have risen the most:
| City | Percentage change | Avg home price in July 2005 | Avg home price in July 2025 |
|---|---|---|---|
| Vancouver | 175% | $306,000 | $842,000 |
| Montreal | 167% | $156,000 | $417,000 |
| Toronto | 164% | $268,000 | $709,000 |

| Baltimore | 45% | $278,000 | $404,000 |
| Washington | 41% | $414,000 | $585,000 |
| Chicago | 41% | $246,000 | $346,000 |
*Inland Empire refers to Riverside-San Bernardino-Ontario, California metro area.
The top three fastest-appreciating cities are all in Canada. Vancouver leads with a 175% increase since 2005, followed by Montreal at 167% and Toronto with a 165% rise.
Canada’s big metros have experienced rapid population growth and strong foreign-buyer interest, combining to create some of the world’s hottest real estate markets. Vancouver and Toronto, in particular, have faced long-term housing shortages and rank among America’s least affordable housing markets.
In the United States, cities in the Sunbelt region in the South have seen their home prices more than double since 2005. These include Dallas (140%), Charlotte (134%), and Denver (125%), followed by Seattle (119%), which is the only more northern metro among the top five U.S. cities.
Houston and Atlanta have also seen strong growth in home prices, along with Miami and Tampa in Florida.
Despite being the three most expensive housing markets, major coastal cities like San Francisco (80%), Los Angeles (73%), and San Diego (71%) show relatively slower growth in home prices. On the East Coast, prices in New York have also grown moderately, rising 60% over the last two decades.
These coastal metros were already expensive in 2005, leaving less room for percentage-based appreciation as compared to Southern cities like Dallas and Houston.
Meanwhile, among the top 25 cities, home prices have grown slowest in Washington, D.C. and Chicago, rising 41% between 2005 and 2025.

The world’s largest regional seas span a wide range of climates, from the warm tropics to the frigid waters around Antarctica. They are major subdivisions of the global ocean system, often defined by surrounding landmasses or submarine ridges.
This visualization highlights the 30 largest regional seas on Earth by surface area, ranging from the vast Philippine Sea to the chilly Labrador Sea. The data for this visualization comes from Wikipedia.
The term “sea” is not rigidly defined, and in this dataset it refers primarily to large subdivisions of the global ocean rather than isolated inland water bodies. These boundaries often follow continental margins, island arcs, or oceanic ridges.
The Philippine Sea stands out as the world’s largest regional sea at nearly 5.7 million km², making it more than twice the size of the Mediterranean. Its vast expanse hosts some of the planet’s deepest ocean trenches and most active tectonic zones.
The neighboring Coral Sea, the second largest, is home to the Great Barrier Reef and is a major reservoir of marine biodiversity.
| Rank | Name | Area_km2 | Area_sq_mi |
|---|---|---|---|
| 1 | Philippine Sea | 5,695,000 | 2,199,000 |
| 2 | Coral Sea | 4,791,000 | 1,850,000 |
| 3 | Arabian Sea | 3,862,000 | 1,491,000 |

| 25 | Argentine Sea | 1,000,000 | 390,000 |
| 26 | East Siberian Sea | 987,000 | 381,000 |
| 27 | Lazarev Sea | 929,000 | 359,000 |
| 28 | Kara Sea | 926,000 | 358,000 |
| 29 | Scotia Sea | 900,000 | 350,000 |
| 30 | Labrador Sea | 841,000 | 325,000 |
The Arabian Sea and the South China Sea both rank within the top five and serve as critical hubs for global shipping. Their warm waters support major monsoon systems that shape regional climates and agriculture.
Further west, the Caribbean Sea and Gulf of Guinea play key roles in trade and energy transport.
Several polar seas also make the list, including the Weddell, Barents, and Greenland Seas. These regions are essential for deep-water formation, a process that helps drive global ocean circulation.
Their extreme climates limit human activity, yet they store significant carbon and influence sea ice patterns. As climate change reshapes the poles, these remote seas will become even more important for understanding Earth’s shifting systems.

| 47 | Wyoming | 34.6% |
| 48 | North Dakota | 33.1% |
| 49 | Utah | 27.7% |
Several Northeastern states, including Rhode Island, New York, Massachusetts, and Vermont, appear near the top of the list. These states often feature strong academic institutions but also high living expenses and tuition rates. Limited public funding contributes to higher student costs compared to the national average.
On the opposite end of the spectrum, Utah is the most affordable state with college costs representing just 27.7% of household income. This reflects low tuition, efficient public university systems, and strong funding models. Institutions in the state often offer programs for low-income students, including incentives that provide free tuition and fees.
North Dakota and Wyoming also remain cost-effective, supported by relatively low fees and competitive state investment.

| 49 | New York City (Brooklyn) | NY | 5 | 130 |
| 50 | San Francisco | CA | 5 | 41 |
St. Louis and Baltimore also remain among the highest-rate cities. Together, these cities highlight the concentration of elevated homicide levels in portions of the South and Midwest.
Chicago, for example, recorded more than 800 homicides but ranks 16th with a rate of 16 per 100,000.
Houston, Los Angeles, and New York City boroughs show similar patterns. These cases demonstrate why total homicide numbers can be misleading when comparing risk across cities.
Cities like Richmond, Indianapolis, and Milwaukee register rates between 20 and 23 per 100,000, placing them among the top 15 nationally. Although smaller in population, these mid-sized cities face similar drivers of violent crime found in larger metropolitan areas.

Global car sales continue to shift as legacy brands defend their share against fast-growing electric vehicle makers. In the first half of 2025, Toyota again led the global market by a wide margin, while several Asian automakers held strong positions across the top 15. This visualization highlights how each automaker performed, comparing unit sales with annual growth rates.
A notable trend is the rise of Chinese manufacturers, especially BYD and Geely, which are expanding both domestically and internationally. Their rapid growth contrasts with declines seen among several established brands in Europe and Japan.
The data for this visualization comes from industry analyst Felipe Munoz, who compiles official manufacturer sales results and estimates for global light-vehicle markets. The numbers include both internal combustion and electric vehicles.
Toyota sold more than double the units of most competitors, reaching 4.73 million vehicles in H1 2025. This represents 6% year-over-year growth, reinforcing Toyota’s strength across markets from North America to Asia. Despite ongoing industry electrification, Toyota’s broad lineup and global production scale continue to support its leadership position.
| Rank | Brand | Global sales (Units) | Growth (YoY) | Country |
|---|---|---|---|---|
| 1 | Toyota | 4,725,616 | 6% |
Japan |
| 2 | Volkswagen | 2,320,300 | 5% |

BYD ranked fourth globally with just over 2 million units sold, but posted an impressive 31% annual increase, far outpacing every other major brand. At its current trajectory, industry experts expect BYD to surpass Ford by the end of 2025.
This momentum reflects China’s booming EV sector as well as BYD’s aggressive international expansion, particularly in Europe and Latin America.
Several established brands experienced declines, including Honda, Nissan, Mercedes, and Audi, each posting drops between 2% and 7%. European luxury brands also ceded share as demand softened in key markets. Meanwhile, Hyundai, Kia, and Chevrolet saw modest growth.
