Condon","doi":"10.5822/978-1-61091-961-6_3","DOIUrl":"https://doi.org/10.5822/978-1-61091-961-6_3","url":null,"abstract":"In the midst of these three waves already transforming cities, we can clearly discern two fundamental types of development: formal and informal. By 2050 an additional four billion people will live in cities. This number will include all of the world’s new population, including both migrants to cities and internal births. Rural populations will decline almost everywhere. About a third of this new urban population will find a place in already developed areas, filling in and densifying existing cities. Another third of them will find a home in entirely new planned or “formal” districts. The last third, or 1.3 billion, will find a home in unplanned, or “informal” districts.1 Assuming an average family size in line with global averages of five persons per household,2 new urban inhabitants will need around 800 million dwelling units, two thirds of that on currently un-urbanized sites. At sustainable middle level densities of about fifteen dwelling units per acre, the 530 million new dwelling units built on new land would consume 35 million acres, or about 55,000 square miles. That is about the size of the state of Michigan. That’s a lot of new urban area to design. It can be argued that all of that new development should be in the form of infill, squeezing new units into the footprint of existing cities, but many global cities will increase by a factor of ten in the next 40 years, presenting impossible barriers for pure infill. This is not to say that infill is unimportant, especially in the developed world, where urban space has often been squandered to feed the rapacious appetites of the urban sprawl machine.","PeriodicalId":165521,"journal":{"name":"Five Rules for Tomorrow’s Cities","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115762172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
