In 2021, the Google Research Africa team launched Open Buildings, an open-source dataset of building footprints across the Global South produced using AI and high-resolution satellite imagery. The team had a simple vision: to fill a major gap in data for population and density in the developing world. Now in its third version, their dataset contains polygons for 1.8 billion buildings over an area of 58 million km² in Africa, South and Southeast Asia, Latin America and the Caribbean. — Google
The data is useful in determining population size and other factors to solve urban density problems. Google's Research product manager Olivia Graham says: "About 2.5 billion more people could move to cities by 2050, most of them in the Global South — this could be a real step... View full entry
The global market for digital twin buildings is now on track to reach a projected market size of $20.2 billion by the year 2032, skyrocketing via a 32.6% CAGR from its current market of $1.6 billion. This is according to the latest reporting from Astute Analytica. The companies leading the charge... View full entry
The toll of urbanization in China has been documented in a new paper published in the journal Science by a team of researchers from different institutions around the country. Using a method called spaceborne synthetic aperture radar interferometry (or InSAR), they were able to establish the rate... View full entry
The implications of this massive decline in population will bring unprecedented challenges, possibly leading to disruptions in basic services like transit, clean water, electricity and internet access. Simultaneously, increasing population trends in resource-intensive suburban and periurban cities will probably take away access to much needed resources in depopulating areas, further exacerbating their challenges. — Nature
Almost half (43%) of the 30,000 cities surveyed recently by the University of Illinois Chicago are expected to lose population while another 40% — among the country’s larger metros such as New York City and Phoenix — will experience growth through the end of this century. Lead... View full entry
The U.S. Census Bureau has changed its definition of an urban area, which will cause hundreds of existing urban areas to be reclassified as rural. The change is centered on a new methodology for how urban areas are calculated, with the number of housing units being used as the key metric, rather... View full entry
Under the ambitious “Lantau Tomorrow” plan, Hong Kong will first build a roughly 2,500-acre island—roughly the size of 1,000 football fields—around the uninhabited Kau Yi Chau Island to the northeast of Lantau. This may be followed by an additional 1,700 additional acres of land reclamation around the island Hei Ling Chau, which is roughly two miles from Mui Wo and visible from its shoreline. — CityLab
CityLab reports that under a new aggressive urban growth plan, Hong Kong will create a pair of new islands totaling over 3,200 acres in area in order to create new high-density urban neighborhoods. Record-breaking affordability issues on the island have pushed wait times for public... View full entry
It's a small, dense, island nation where 100% of the population is urbanized. And yet, the city-state of Singapore is the greenest city in Asia, according to the Green City Index, and arguably has few competitors in the rest of the world. As Singapore's population and economy grew, so did its green cover: it was about 36% in the 1980s and it now stands at 47%, according to the Center for Liveable cities. — CNN
Becoming one of the "must-see" places in the world, Singapore has created a name for itself amongst travelers. Even Hollywood has already capitalized on the nation's likability and illustrious cityscape thanks to the top-grossing film, Crazy Rich Asians. However, beyond the food and Instagramable...

Mayor Byron Brown said there will be a significant change documented in the 2020 Census for Buffalo. "We believe that in the 2020 census will allow Buffalo to show its first population growth since the 1950 census,” he said. — Spectrum News
After nearly 70 years of population declines, The City of Good Neighbors is growing once again. According to Buffalo mayor Byron W. Brown, the city could register significant population growth after the 2020 Census, a product, in part, of the city's growing refugee and immigrant communities... View full entry
Phoenix and its surrounding area is known as the Valley of the Sun, and downtown Phoenix – which in 2017 overtook Philadelphia as America’s fifth-largest city – is easily walkable, with restaurants, bars and an evening buzz. But it is a modern shrine to towering concrete, and gives way to endless sprawl that stretches up to 35 miles away to places like Anthem. The area is still growing – and is dangerously overstretched, experts warn. — The Guardian
With cities in the Desert West, like Las Vegas and Phoenix, rapidly growing in size and population, water is becoming an evermore hot commodity; all while the source of that water, primarily the Colorado River, is becoming increasingly unreliable due to climate change. "And yet despite the federal... View full entry
Making the case that infrastructure itself can be exclusionary is hardly straightforward. Many of the worst decisions in US planning were made decades ago to intentionally disenfranchise, marginalise and separate communities; policies such as redlining and “blight clearing” are well-documented embarrassments. But many decisions that segregated communities were unintentional. The stop sign and one-way street might seem benign, but they shape our lives in ways we sometimes don’t even realise. — The Guardian
Through focusing in on 5 case studies where communities have been obliterated by infrastructure decisions, the direct impact of highways and walls take on greater levels of meaning and urgency. The power of city planning also comes into greater consideration presently as the US takes on a massive... View full entry

The inevitable, and accelerating, growth of cities is an undisputed premise in contemporary urbanist discourses. With the rapid rise of entirely new cities proliferating around the globe, questions arise of how much in urban life can be improved with a blank slate. This short film from The... View full entry
Up to 12 million people are “urbanising” every year in India, a rate surpassed only by China. It means the country will need a sustained building spree that would see more than 75 million people employed in construction by 2022.
As it races to build 110 million extra homes needed, plus necessary transport infrastructure, by 2025 the size of India’s construction market would reach $1 trillion, the third largest in the world, according to KPMG.
