This article is about the demographic features of the population of Switzerland, including population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects of the population. Switzerland had a population of 8.02 million as of 2012. Its population quadrupled over the period 1800 to 1990 (average doubling time 95 years). Population growth was steepest in the period after World War II (1.4% per annum during 1950-1970, doubling time 50 years), it slowed down during the 1970s to 1980s and has since again picked up to 1% during the 2000s (doubling time 70 years). More than 75% of the population live in the central plain, which stretches between the Alps and the Jura Mountains and from Geneva in the southwest to the Rhine River and Lake Constance in the northeast. Foreigners with permanent residency (which does not include temporary foreign workers) make up about 23% of the population. ==Census== (詳細はFederal Councillor Stefano Franscini, who evaluated the data of the first census all by himself after Parliament failed to provide the necessary funds.〔(History of the Federal Population Census ), Swiss Federal Statistical Office, accessed October 2007〕 The census is now being conducted by the Swiss Federal Statistical Office, which makes most results available on its (website ). Collected data includes population data (citizenship, place of residence, place of birth, position in household, number of children, religion, languages, education, profession, place of work, etc.), household data (number of individuals living in the household, etc.), accommodation data (surface area, amount of rent paid, etc.) and building data (geocoordinates, time of construction, number of floors, etc.). Participation is compulsory and reached 99.87% of the population in 2000.〔(Overview of the Federal Population Census ), Swiss Federal Statistical Office, accessed October 2007〕 Since 2010, the population census has been carried out and analysed annually in a new format by the Federal Statistical Office (FSO). In order to ease the burden on the population, the information is primarily drawn from population registers and supplemented by sample surveys. Only a small proportion of the population (about 5%) are surveyed in writing or by telephone. The first reference day for the new census was 31 December 2010. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Demographics of Switzerland」の詳細全文を読む スポンサード リンク
