Brazil's population is very diverse, comprising many races and ethnic groups. In general, Brazilians trace their origins from four sources: Amerindians, Europeans, Africans and Asians. Brazil has conducted a periodical population census since 1872. Since 1940, this census has been carried out decennially. Scanned versions of the forms for each census distributed in Brazil since 1960 are available on-line from IPUMS International.〔(IPUMS International )〕 Historically, Brazil has experienced large degrees of ethnic and racial admixture, assimilation of cultures and syncretism. ==Population== According to the 2008 PNAD (National Household Sample Survey), conducted by the IBGE, the Brazilian Statistics bureau, there were about 189,953,000 inhabitants in 2008.〔IBGE. (2008 PNAD )〕 As of the latest (2010) census, the Brazilian government estimates its population at 190.8 million. The population of Brazil is estimated based on various sources from 1550 to 1850. The first official census took place in 1872. From that year, every 10 years (with some exceptions) the population is counted. Brazil is the fifth most populated country in the world. * 1550 – 15,000 * 1600 – 100,000 * 1660 – 184,000 * 1700 – 300,000 * 1766 – 1,500,000 * 1800 – 3,250,000 * 1820 – 4,717,000 * 1850 – 7,256,000 * 1872 – 9,930,478 * 1890 – 14,333,915 * 1900 – 17,438,434 * 1920 – 30,635,605 * 1940 – 41,236,315 * 1950 – 51,944,397 * 1960 – 70,119,071 * 1970 – 93,139,037 * 1980 – 119,070,865 * 1991 – 146,917,459 * 1996 – 157,079,573 * 2000 – 169,544,443 * 2010 – 192,755,799〔(Government of Brazil )〕 * 2015 – 〔(IBGE – Official population clock )〕 Population distribution in Brazil is very uneven. The majority of Brazilians live within 300 kilometers of the coast, while the interior in the Amazon Basin is almost empty. Therefore, the densely populated areas are on the coast and the sparsely populated areas are in the interior. This historical pattern is little changed by recent movements into the interior. 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 Brazil」の詳細全文を読む スポンサード リンク
