A couple of decades ago, the urban environment was considered child-friendly if there was a playground next to the house. Today, urbanists suggest the 'popsicle test': if a kid can safely walk to a store, buy a popsicle, and return home before it melts, a city can be considered child friendly.
Safe recreation areas are necessary to create child-friendly cities. However, city planners still must solve the problem of designing sustainable and inclusive architectural environments relevant for both adults and children. A child does not choose which city to live in and even in the same city, children can seem to live in entirely different places because of the extreme variation of infrastructural facilities. There are several local and global projects that have effectively responded to this issue. For example, in a few neighborhoods in Philadelphia, the USA, Playful Learning Landscapes placed posters with puzzles and fun facts at bus stops. These games aimed to improve spatial and math skills. The Supermarket Speak project was held in local grocery stores and turned a mundane errand into an educational quest for the whole family. A prime example of large-scale initiatives is the redesign of busy streets into new playing areas in Cape Town, Bogota, and Barcelona; air quality study in primary schools in Berlin, London, Paris, Madrid, and Warsaw.
