Megalopolis: The Latest Architecture and News

As of today, over 50% of the world’s population lives in urban areas, and by 2050, this urban population will almost double in size, and 7 of 10 people in the world will live in cities. As cities have continued to grow and expand throughout history, a new vocabulary has also emerged, often to better communicate the scale of urban living in a relatively contemporary context. One such example is the term megalopolis – typically defined as a network of large cities that have been interconnected with surrounding metropolitan areas by infrastructure or transportation. In effect, it’s a region perceived as an encompassing urban area, within which there is a constant flow of commerce and migration.

As is obvious to anyone with even a passing interest in demographics, cities are becoming denser—much denser. Rural life continues its steady emptying-out as urban life accelerates its explosive filling-in. The tilt has been apparent at least since the middle of the last century when the French geographer Jean Gottmann invented the word “megalopolis” to describe the continuous urbanization from Boston to Washington, D.C., then containing one-fifth of the United States’ population. But nowhere has the shift from countryside to city been more dramatic than in present-day Asia. 

You can’t define modern civilization without mentioning its cities. These urban settlements vary in culture, size and specialty, with certain areas becoming more significant throughout the development of a region. Historically, the size or population of a settlement was a general indicator of its importance—the bigger city, the more power it yields—however, with the large rural-to-urban migration of the last century, it has become harder to define what makes a city important. There are many types of urban landscapes, and for architects and planners it is vital to efficiently categorize settlement types in order to successfully develop designs and city plans. The following list provides four key definitions that have emerged in the last century.
