the city borders. Calgary is unusual among Canadian cities because it has developed as a unicity – it has annexed most of its surrounding towns and large amounts of undeveloped land around the city. As a result, most of the communities that Calgarians refer to as "suburbs" are actually inside the city limits. In the 2016 census, the City of Calgary had a population of 1,239,220, whereas the Calgary Metropolitan Area had a population of 1,392,609, indicating the vast majority of people in the Calgary CMA lived within the city limits. The perceived low population density of Calgary largely results from its many internal suburbs and the large amount of undeveloped land within the city. The city actually has a policy of densifying its new developments. China In China, the term suburb is new, although suburbs are already being constructed rapidly. Chinese suburbs mostly consist of rows upon rows of apartment blocks and condos that end abruptly into the countryside. Also new town developments are extremely common. Single family suburban homes tend to be similar to their Western equivalents; although primarily outside Beijing and Shanghai, also mimic Spanish and Italian architecture. Hong Kong In Hong Kong, however, suburbs are mostly government-planned new towns containing numerous public housing estates. However, other new towns also contain private housing estates and low density developments for the upper classes. Italy In the illustrative case of Rome, Italy, in the 1920s and 1930s, suburbs were intentionally created ex novo to give lower classes a destination, in consideration of the actual and foreseen massive arrival of poor people from other areas of the country. Many critics have seen in this development pattern (which was circularly distributed in every direction) also a quick solution to a problem of public order (keeping the unwelcome poorest classes together with the criminals, in this way better controlled, comfortably remote from the elegant "official" town). On the other hand, the expected huge expansion of the town soon effectively covered the distance from the central town, and now those suburbs are completely engulfed by the main territory of the town. Other newer suburbs (called exurbs) were created at a further distance from them. Japan In Japan, the construction of suburbs has boomed since the end of World War II and many cities are experiencing the urban sprawl effect. Latin America In Mexico, suburbs are generally similar to their United States counterparts. Houses
