How We Share the World This interactive graphic shows how the world is divided according to six different socioeconomic variables. The land area of each country represents its share of the worldwide total. Click on a circle to reshape the map For attribution and data sources, scroll to the bottom. I have been having fun experimenting with cartograms lately. World's biggest cities merging into mega-regions The world's mega-cities are merging to form vast "mega-regions" which may stretch hundreds of kilometres across countries and be home to more than 100 million people, according to a major new UN report. The phenomenon of the so-called "endless city" could be one of the most significant developments - and problems - in the way people live and economies grow in the next 50 years, says UN-Habitat, the agency for human settlements, which identifies the trend of developing mega-regions in its biannual State of World Cities report. The largest of these, says the report - launched today at the World Urban Forum in Rio de Janeiro - is the Hong Kong-Shenhzen-Guangzhou region in China, home to about 120 million people. Other mega-regions have formed in Japan and Brazil and are developing in India, west Africa and elsewhere.

Survival in megacities More than 60% of humanity will be living in cities by 2030, ­according to a United Nations forecast. Megacities – i.e. cities with more than 10 million inhabitants – are growing especially fast. The more these gigantic cities grow, the bigger the challenges also become. City dwellers all over the world want – and deserve – healthy air to breathe, clean drinking water, a good energy supply and a functioning health system. They also want to be mobile – so transport systems have to be able to move millions of people while remaining as environmentally friendly and cost-effective as possible. In other words, without a well-functioning infrastructure there is no quality of life.

Streets of London Leaflet | Map data © OpenStreetMap contributors, CC-BY-SA, Imagery © CartoDB Made by Google Maps Mania Slum Rehabilitation Promise to Mumbai’s 20 Million Slums, shanty-towns, favelas - they are all products of an exploding migration from rural to urban areas. Over the last half century, people living in or near metropolises has risen in proportion to the global population. Migrations from rural areas to urban areas have grown exponentially as cities have developed into hubs of economic activity and job growth promising new opportunities for social mobility and education. Les dix meilleurs cartes de la ville de New york en 2015 Despite spending an inordinate amount of time each day looking at maps, it is beyond me to select a list of the best maps from among everything posted last year on the web. There are far too many, more than I could ever hope to find, for the list to have any real meaning. Sticking to what I know best, I have compiled my favorite maps of 2015 that cover New York City.

Mega-Region Development The development of mega regions is mostly the outcome of three processes that reinforce the spatial extent and the coherence of an urban system. The first is the growth, intensification and diffusion of economic activities, which requires additional amounts of urban land. The second is the growing interconnectivity of urban centers, mostly through the setting of multimodal transport corridors. Safe Shelter, Health and Wellbeing in Poorest Cities This Human Rights Day, let's talk about housing. We've been paying more attention to housing here in the U.S. lately, given the calamitous impact of Hurricane Sandy on entire New York and New Jersey communities and the countless American families with homes still in foreclosure. Globally, of course, the situation is even more dire. More than a billion people -- a sixth of the world's population -- live in slums; an additional 600 million inhabit substandard housing, another 100 million are homeless altogether, and every single week, more than a million are born or move into developing world cities. In-migration from failed harvests, climate change and the draw of urban opportunities has dramatically upped the pressure on these cities, where entire neighborhoods lack streets and drainage, clean water and sanitation, electricity, clinics and jobs, and yet the people keep coming.
