Demographics of Bolivia
The demographic characteristics of the population of Bolivia are known from censuses, with the first census undertaken in 1826 and the most recent in 2012. The National Institute of Statistics of Bolivia (INE) has performed this task since 1950. The population of Bolivia in 2012 reached 10 million for the first time in history. The population density is 9.13 inhabitants per square kilometer, and the overall life expectancy in Bolivia at birth is 68.2 years. The population has steadily risen from the late 1800s to the present time. The natural growth rate of the population is positive , which has been a continuing trend since the 1950s; in 2012, Bolivia's birth rate continued to be higher than the death rate. Bolivia is in the third stage of demographic transition. In terms of age structure, the population is dominated by the 15–64 segment. The median age of the population is 23.1, and the gender ratio of the total population is 0.99 males per female. Bolivia is inhabited mostly by Quechua (45.6%) and Aymara (42.4%), while minorities include 37 indigenous groups (0.3% average per group). Spanish, Quechua, Aymara, Guarani languages, as well as 34 other native languages are the  official language of Bolivia. Spanish is the most-spoken language (60.7%) within the population. The main religions of Bolivia are the Catholic Church (81.8%), Evangelicalism (11.5%), and Protestantism (2.6%). There is a literacy rate of 91.2%. An estimated 7.6% of the country's gross domestic product (GDP) is spent on education. The average monthly household income was Bs.1,378 ($293) in 1994. In December 2013 the unemployment rate was 3.2% of the working population. The average urbanization rate in Bolivia is 67%. Population. The first true estimate of the population of Bolivia came in 1826, in which 997,427 inhabitants were  estimated. This number was calculated from the 1796 census organized by Francisco Gil de Taboada, which consisted of several Bolivian cities. The first modern census was completed in 1831, and ten have been completed since then. The organizer of Bolivia's censuses has changed throughout the years—Andrés de Santa Cruz (1831), The Bolivian Statistical Office (1835, 1854, 1882), The Bolivian Statistical Commission (1845), The National Immigration Bureau and The Statistics and Geographic Propaganda (1900), and The Department of Statistics and Censuses (1950)—with the INE conducting the census since 1976. The national census is supposed to be conducted every ten  years, however, the 2012 census was late because of "climatic factors and the financing." The 2012 census was conducted on 21 November 2012, in which 10,027,254 inhabitants were in the country. The estimated cost of the census was $50 million. With a population of 10.0 million in 2012, Bolivia ranks 87th in the world by population. Its population density is 9.13 inhabitants per square kilometer. The overall life expectancy in Bolivia is 65.4. The total fertility rate is 2.87 children per mother. Since 1950, the World Health Organization (WHO) estimates the birth rate exceeded the death rate of the  country. The population of Bolivia has been increasing since 1900, and has only had a negative per annum growth rate twice in its history (1835 and 1882). Bolivia is in the third stage of demographic transition. There were 562,461 immigrants in Bolivia in 2012, with the most (40.5%) coming from Argentina.
