A census is the procedure of systematically acquiring and recording information about the members of a given population. The term is used in connection with national population and housing censuses; the United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory and defined periodicity", recommends that population censuses be taken at least every 10 years. United Nations recommendations cover census topics to be collected, official definitions and other useful information to co-ordinate international practice; the word is of Latin origin: during the Roman Republic, the census was a list that kept track of all adult males fit for military service. The modern census is essential to international comparisons of any kind of statistics, censuses collect data on many attributes of a population, not just how many people there are. Censuses began as the only method of collecting national demographic data, are now part of a larger system of different surveys.
Although population estimates remain an important function of a census, including the geographic distribution of the population, statistics can be produced about combinations of attributes e.g. education by age and sex in different regions. Current administrative data systems allow for other approaches to enumeration with the same level of detail but raise concerns about privacy and the possibility of biasing estimates. A census can be contrasted with sampling in which information is obtained only from a subset of a population. Modern census data are used for research, business marketing, planning, as a baseline for designing sample surveys by providing a sampling frame such as an address register. Census counts are necessary to adjust samples to be representative of a population by weighting them as is common in opinion polling. Stratification requires knowledge of the relative sizes of different population strata which can be derived from census enumerations. In some countries, the census provides the official counts used to apportion the number of elected representatives to regions.
In many cases, a chosen random sample can provide more accurate information than attempts to get a population census. A census is construed as the opposite of a sample as its intent is to count everyone in a population rather than a fraction. However, population censuses rely on a sampling frame to count the population; this is the only way to be sure that everyone has been included as otherwise those not responding would not be followed up on and individuals could be missed. The fundamental premise of a census is that the population is not known and a new estimate is to be made by the analysis of primary data; the use of a sampling frame is counterintuitive as it suggests that the population size is known. However, a census is used to collect attribute data on the individuals in the nation; this process of sampling marks the difference between historical census, a house to house process or the product of an imperial decree, the modern statistical project. The sampling frame used by census is always an address register.
Thus it is not known how many people there are in each household. Depending on the mode of enumeration, a form is sent to the householder, an enumerator calls, or administrative records for the dwelling are accessed; as a preliminary to the dispatch of forms, census workers will check any address problems on the ground. While it may seem straightforward to use the postal service file for this purpose, this can be out of date and some dwellings may contain a number of independent households. A particular problem is what are termed'communal establishments' which category includes student residences, religious orders, homes for the elderly, people in prisons etc; as these are not enumerated by a single householder, they are treated differently and visited by special teams of census workers to ensure they are classified appropriately. Individuals are counted within households and information is collected about the household structure and the housing. For this reason international documents refer to censuses of housing.
The census response is made by a household, indicating details of individuals resident there. An important aspect of census enumerations is determining which individuals can be counted from which cannot be counted. Broadly, three definitions can be used: de facto residence; this is important to consider individuals who have temporary addresses. Every person should be identified uniquely as resident in one place but where they happen to be on Census Day, their de facto residence, may not be the best place to count them. Where an individual uses services may be more useful and this is at their usual, or de jure, residence. An individual may be represented at a permanent address a family home for students or long term migrants, it is necessary to have a precise definition of residence to decide whether visitors to a country should be included in the population count. This is becoming more important as students travel abroad for education for a period of several years. Other groups causing problems of enumeration are new born babies, people away on holiday, people moving home around census day, people without a fixed address.
People having second homes because of working in another part of the country or retaining a holiday cottage are dif
Tertiary sector of the economy
The tertiary sector or service sector is the third of the three economic sectors of the three-sector theory. The others are the secondary sector, the primary sector; the service sector consists of the production of services instead of end products. Services include attention, access and affective labor; the production of information has long been regarded as a service, but some economists now attribute it to a fourth sector, the quaternary sector. The tertiary sector of industry involves the provision of services to other businesses as well as final consumers. Services may involve the transport and sale of goods from producer to a consumer, as may happen in wholesaling and retailing, pest control or entertainment; the goods may be transformed in the process of providing the service, as happens in the restaurant industry. However, the focus is on people interacting with people and serving the customer rather than transforming physical goods, it is sometimes hard to define whether a given company is part and parcel of the secondary or tertiary sector.
And it is not only companies. In order to classify a business as a service, one can use classification systems such as the United Nations' International Standard Industrial Classification standard, the United States' Standard Industrial Classification code system and its new replacement, the North American Industrial Classification System, the Statistical Classification of Economic Activities in the European Community in the EU and similar systems elsewhere; these governmental classification systems have a first-level hierarchy that reflects whether the economic goods are tangible or intangible. For purposes of finance and market research, market-based classification systems such as the Global Industry Classification Standard and the Industry Classification Benchmark are used to classify businesses that participate in the service sector. Unlike governmental classification systems, the first level of market-based classification systems divides the economy into functionally related markets or industries.
The second or third level of these hierarchies reflects whether goods or services are produced. For the last 100 years, there has been a substantial shift from the primary and secondary sectors to the tertiary sector in industrialized countries; this shift is called tertiarisation. The tertiary sector is now the largest sector of the economy in the Western world, is the fastest-growing sector. In examining the growth of the service sector in the early Nineties, the globalist Kenichi Ohmae noted that: "In the United States 70 percent of the workforce works in the service sector; these are not busboys and live-in maids. Many of them are in the professional category, they are earning as much as manufacturing workers, more.”Economies tend to follow a developmental progression that takes them from a heavy reliance on agriculture and mining, toward the development of manufacturing and toward a more service-based structure. The first economy to follow this path in the modern world was the United Kingdom.
The speed at which other economies have made the transition to service-based economies has increased over time. Manufacturing tended to be more open to international trade and competition than services. However, with dramatic cost reduction and speed and reliability improvements in the transportation of people and the communication of information, the service sector now includes some of the most intensive international competition, despite residual protectionism. Service providers face obstacles selling services that goods-sellers face. Services are intangible, making it difficult for potential customers to understand what they will receive and what value it will hold for them. Indeed, such as consultants and providers of investment services, offer no guarantees of the value for price paid. Since the quality of most services depends on the quality of the individuals providing the services, "people costs" are a high fraction of service costs. Whereas a manufacturer may use technology and other techniques to lower the cost of goods sold, the service provider faces an unrelenting pattern of increasing costs.
Product differentiation is difficult. For example, how does one choose one investment adviser over another, since they are seen to provide identical services? Charging a premium for services is an option only for the most established firms, who charge extra based upon brand recognition. Examples of tertiary industries may include: Telecommunication Hospitality industry/tourism Mass media Healthcare/hospitals Public health Pharmacy Information technology Waste disposal Consulting Gambling Retail sales Fast-moving consumer goods Franchising Real estate Education Financial services Banking Insurance Investment management Professional services Accounting Legal services Management consultingTransportation Below is a list of countries by service output at market exchange rates in 2016.

In biology, a population is all the organisms of the same group or species, which live in a particular geographical area, have the capability of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area, where the probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas. In sociology, population refers to a collection of humans. Demography is a social science. Population in simpler terms is the number of people in a city or town, country or world. In population genetics a sex population is a set of organisms in which any pair of members can breed together; this means that they can exchange gametes to produce normally-fertile offspring, such a breeding group is known therefore as a Gamo deme. This implies that all members belong to the same species. If the Gamo deme is large, all gene alleles are uniformly distributed by the gametes within it, the Gamo deme is said to be panmictic.
Under this state, allele frequencies can be converted to genotype frequencies by expanding an appropriate quadratic equation, as shown by Sir Ronald Fisher in his establishment of quantitative genetics. This occurs in Nature: localization of gamete exchange – through dispersal limitations, preferential mating, cataclysm, or other cause – may lead to small actual Gamo demes which exchange gametes reasonably uniformly within themselves but are separated from their neighboring Gamo demes. However, there may be low frequencies of exchange with these neighbors; this may be viewed as the breaking up of a large sexual population into smaller overlapping sexual populations. This failure of panmixia leads to two important changes in overall population structure: the component Gamo demos vary in their allele frequencies when compared with each other and with the theoretical panmictic original; the overall rise in homozygosity is quantified by the inbreeding coefficient. Note that all homozygotes are increased in frequency – both the deleterious and the desirable.
The mean phenotype of the Gamo demes collection is lower than that of the panmictic original –, known as inbreeding depression. It is most important to note, that some dispersion lines will be superior to the panmictic original, while some will be about the same, some will be inferior; the probabilities of each can be estimated from those binomial equations. In plant and animal breeding, procedures have been developed which deliberately utilize the effects of dispersion, it can be shown that dispersion-assisted selection leads to the greatest genetic advance, is much more powerful than selection acting without attendant dispersion. This is so for both autogamous Gamo demes. In ecology, the population of a certain species in a certain area can be estimated using the Lincoln Index. According to the United States Census Bureau the world's population was about 7.55 billion in 2019 and that the 7 billion number was surpassed on 12 March 2012. According to a separate estimate by the United Nations, Earth’s population exceeded seven billion in October 2011, a milestone that offers unprecedented challenges and opportunities to all of humanity, according to UNFPA, the United Nations Population Fund.
According to papers published by the United States Census Bureau, the world population hit 6.5 billion on 24 February 2006. The United Nations Population Fund designated 12 October 1999 as the approximate day on which world population reached 6 billion; this was about 12 years after world population reached 5 billion in 1987, 6 years after world population reached 5.5 billion in 1993. The population of countries such as Nigeria, is not known to the nearest million, so there is a considerable margin of error in such estimates. Researcher Carl Haub calculated that a total of over 100 billion people have been born in the last 2000 years. Population growth increased as the Industrial Revolution gathered pace from 1700 onwards; the last 50 years have seen a yet more rapid increase in the rate of population growth due to medical advances and substantial increases in agricultural productivity beginning in the 1960s, made by the Green Revolution. In 2017 the United Nations Population Division projected that the world's population will reach about 9.8 billion in 2050 and 11.2 billion in 2100.
In the future, the world's population is expected to peak, after which it will decline due to economic reasons, health concerns, land exhaustion and environmental hazards. According to one report, it is likely that the world's population will stop growing before the end of the 21st century. Further, there is some likelihood that population will decline before 2100. Population has declined in the last decade or two in Eastern Europe, the Baltics and in the Commonwealth of Independent States; the population pattern of less-developed regions of the world in recent years has been marked by increasing birth rates. These followed an earlier sharp reduction in death rates; this transition from high birth and death rates to low birth
Chuquisaca is a department of Bolivia located in the center south. It borders on the departments of Cochabamba, Potosí, Santa Cruz; the departmental capital is Sucre, the constitutional capital of Bolivia. The department is traversed by the main cordillera of the Andes mountain range and lesser cordilleras. Parts of it lie within the basin of the Amazon River, other parts within the basin of the Río de La Plata; the surface area of the department is 51,524 square kilometers. The topography of central Chuquisaca consists of a series of ridges rising up to 1500 m that run north and south with flat valleys between the ridges. To the west of these ridges abruptly rise the Andes Mountains to 3000 m forming a prepuna landmass, cut into by large river valleys that drain into the Amazon or Rio de la Plata river basins. To the east of the central ridges lies a stretch of territory containing low altitude flat Chaco topography. 90% of the land in the department of Chuquisaca has an inclination of 70% or more.
Ecological and vegetation zones in the department of Chuquisaca vary according to a diversity of abiotic factors including soil formation and textures, rainfall patterns, mineral and salinity content of water. Altitude plays an important role in the dispersion of vegetation species and wider ecosystems as they respond to microclimates; as the Andes Mountains became uplifted, plants adapted to dryer and higher microclimates resulting in a high level of speciation in the dry forest river valleys of the Bolivian-Tucuman formation. Colder and drier air from more austral parts of South America have resulted in migration of plant communities with a floristic connection to those in Argentina and Southern Brazil as opposed to more tropical plant communities that result from warm and moist northern climates. Navarro and Ferreira have developed a database of plant species in Bolivia and identified 39 separate vegetation zones in Bolivia within twelve general physiographic-biogeographical units of which four fall in the boundaries of Chuquisaca Department including: Cordillera Oriental Central y Meridional, Prepuna or High Interandean Valleys, Bolivian-Tucuman Formation, Chaco.
Using Navarro and Ferreira’s categories and descriptions based on vegetation zones, the geographical and ecological characteristics of the Chuquisaca Department can be described as follows. Cordillera Oriental Central y Meridional: From an altitude of 3200m in Chuquisaca to nearly 6000 meters in Potosi, this zone is characterized by the puna and subnival and nival ecological zones with a pluviestacional subhumed bioclimate. Prepuna or High Interandean Valleys: From 2300m to 3200m, this zone is characterized by a mesotropical dry xeric bioclimatic zone. Seasonally torrential waters and salinity levels affect regional vegetation patterns in this zone. Bolivian-Tucuman Formation: With a wide altitude range between 600m to 3900m this zone contains pluviestacional subhumid and locally humid bioclimatic zones; the high altitude Rio Grande and Pilcomayo river valleys transect this unit and are characterized by dry xeric vegetation zones with endemic and varied speciation in the Rio Grande river valley and vegetation influence from the Chaco in the Pilcomayo river valley.
Wet forest ecosystems like those found in more northern Yungas valleys are found on high ridges where clouds form. Chaco: from 400–900 m this unit is characterized by a xeric bioclimate. Sandy soils in this unit were formed from alluvial processes from the Grande rivers. Soil drainage affects vegetation dispersion within this unit. With a human population of 631,000 people humans are a part of the ecology of Chuquisaca; the grazing of cattle and introduction of invasive feral citrus trees has affected the native plant populations in the department. Native forests and ecosystems have contracted as land has been converted to pasture and erosion is widespread as a result of human agricultural activities on steep slopes; the chief executive office of Bolivia departments is the governor. The current governor, Esteban Urquizu Cuéllar of the Movement for Socialism – Political Instrument for the Sovereignty of the Peoples was elected on 4 April 2010. Under the 2009 Constitution, each Bolivian department has an elected Departmental Legislative Assembly.
The first elections were held 4 April 2010. The majority party in the twenty-one member assembly is the Movement towards Socialism with 15 seats. Four seats are held by We Are All Chuquisaca. Two seats were selected by the Guaraní people through usos y costumbres; the department is divided into 10 provinces which are further subdivided into municipalities and cantons. The native inhabitants were the Charcas, who were dispersed along lowlands, their leaders, jampiris and priests resided in the capital, Choque-Chaca, which according to 17th century chronicles had a population of several thousand. Sucre is called the city of the four names, each name corresponding to a different period of its history, it was founded by the Spaniard Pedro de Anzures in 1538. It thrived due to its regional proximity to the famous silver mines of Potosi, as Charcas served as capital of the Real Audiencia de Charcas, encompassing all of current Bolivia's territory and more. Reverting to its native name of Chuquisaca, it was the Upper Peru's chief administrative center and largest city.
It was there that the first public call for independence from Spain took place, on May 25, 1809, where the Act of Independence from Spanish rule was signed on August 6, 1825
Municipalities of Bolivia
Municipalities in Bolivia are administrative divisions of the entire national territory governed by local elections. Municipalities are the third level of administrative divisions, below provinces; some of the provinces consist of only one municipality. In these cases the municipalities are identical to the provinces. Municipalities in Bolivia are each led by an executive office. Mayors were appointed by the national government from 1878 to 1942 and from 1949 to 1987. Local elections were held under the 1942 municipal code, in force until 1991; the 1985 Organic Law of Municipalities restored local elections for mayor and created a legislative body, the municipal council. In 1994, the entire territory of Bolivia was merged into municipalities, where only urban areas were organized as municipalities; as an effect of decentralization through the 1994 Law of Popular Participation the number of municipalities in Bolivia has risen from an initial twenty-four to 327, to 337, to 339. Of the 327 municipalities existing after 2005, 187 are inhabited by indigenous population.
New municipalities must have 5,000 in the case of border areas. The municipalities are as follows ordered by department: Baures Municipality Exaltación Municipality Guayaramerín Municipality Huacaraje Municipality Loreto Municipality, Beni Magdalena Municipality, Beni Puerto Siles Municipality Reyes Municipality Riberalta Municipality Rurrenabaque Municipality San Andrés Municipality, Beni San Borja Municipality San Ignacio Municipality, Beni San Javier Municipality, Beni San Joaquín Municipality, Beni San Ramón Municipality, Beni Santa Ana Municipality, Beni Santa Rosa Municipality, Beni Trinidad Municipality, Beni Aiquile Municipality Alalay Municipality Anzaldo Municipality Arani Municipality Arbieto Municipality Arque Municipality Ayopaya Municipality Bolívar Municipality, Cochabamba Capinota Municipality Chimoré Municipality Cliza Municipality Cocapata Municipality Cochabamba Municipality Colcapirhua Municipality Colomi Municipality Cuchumuela Municipality Entre Ríos Municipality, Cochabamba Mizque Municipality Morochata Municipality Muela Municipality Omereque Municipality Pasorapa Municipality Pocona Municipality Pojo Municipality Puerto Villarroel Municipality Punata Municipality Quillacollo Municipality Sacaba Municipality Sacabamba Municipality San Benito Municipality Santivañez Municipality Shinahota Municipality / Shinaota Municipality / Sinahota Municipality Sicaya Municipality Sipe Sipe Municipality Tacachi Municipality Tacopaya Municipality Tapacarí Municipality Tarata Municipality Tiquipaya Municipality Tiraque Municipality Toco Municipality Tolata Municipality Totora Municipality Tunari Municipality Vacas Municipality Vila Vila Municipality Vinto Municipality Azurduy Municipality Camargo Municipality, Chuquisaca Culpina Municipality El Villar Municipality Huacareta Municipality Huacaya Municipality Icla Municipality Incahuasi Municipality Mojocoya Municipality Camataqui Municipality Las Carreras Municipality Macharetí Municipality Monteagudo Municipality Padilla Municipality Poroma Municipality Presto Municipality San Lucas Municipality Sopachuy Municipality Sucre Municipality, Bolivia Tarabuco Municipality Tomina Municipality Villa Alcalá Municipality Villa Charcas Municipality Villa Serrano Municipality Villa Vaca Guzmán Municipality Villa Zudañez Municipality Tarvita Municipality Yotala Municipality Yamparáez Municipality Achacachi Municipality Achocalla Municipality Alto Beni Municipality Ancoraimes Municipality Apolo Municipality Aucapata Municipality Ayata Municipality Ayo Ayo Municipality Batallas Municipality Cairoma Municipality Cajuata Municipality Calacoto Municipality Calamarca Municipality Caquiaviri Municipality Caranavi Municipality Catacora Municipality Chacarilla Municipality Charaña Municipality Chúa Cocani Municipality Chulumani Municipality Chuma Municipality Collana Municipality Colquencha Municipality Colquiri Municipality Comanche Municipality Combaya Municipality Copacabana Municipality, La Paz Coripata Municipality Coro Coro Municipality Coroico Municipality Curva Municipality Desaguadero Municipality El Alto Municipality, La Paz Escoma Municipality General Juan José Pérez Municipality Guanay Municipality Guaqui Municipality Huatajata Municipality Huarina Municipality Humanata Municipality Ichoca Municipality Inquisivi Municipality Irupana Municipality Ixiamas Municipality La Asunta Municipality La Paz Municipality Laja Municipality Licoma Pampa Municipality Luribay Municipality Malla Municipality Mecapaca Municipality Mocomoco Municipality Nazacara de Pacajes Municipality Palca Municipality Palos Blancos Municipality Papel Pampa Municipality Patacamaya Municipality Pelechuco Municipality Pucarani Municipality Puerto Acosta Municipality Puerto Carabuco Municipality Puerto Pérez Municipality Quiabaya Municipality Quime Municipality San Buenaventura Municipality, La Paz San Pedro de Curahuara Municipality San Pedro de Tiquina Municipality Santiago de Callapa Municipality Santiago de Huata Municipality Santiago de Machaca Municipality Sapahaqui Municipality Sica Sica Municipality Sorata Municipality Tacacoma Municipality Tiwanaku Municipality Tipuani Municipality Tito Yupanqui Municipality Umala Municipality Viacha Municipality Waldo Ballivián Municipality Yaco Municipality Yanacachi Municipality Andamarca Municipality Antequera Municipality Belén de Andamarca Municipality Caracollo Municipality Carangas Municipality Challapata Municipality Chipaya Municipality Choquecota Municipality Coipasa Municipality Corque Municipality Cruz de Machacamarca Municipality Curahuara de Carangas Municipality El Choro Municipalit
Tarija is a department in Bolivia. It is located in south-eastern Bolivia bordering with Argentina to the south and Paraguay to the east. According to the 2012 census, it has a population of 482,196 inhabitants, it has an area of 37,623 km2. The city of Tarija is the capital of the department; the department is divided into five provinces and one autonomous region: Gran Chaco Province Aniceto Arce Province José María Avilés Province Cercado Province Eustaquio Méndez Province Burdett O'Connor ProvinceNotable places in Tarija include: Villamontes in the department's oil-producing eastern scrubland Bermejo, a border town adjoining Aguas Blancas, Argentina Yacuiba, a border town with Argentina. The Department of Tarija is renowned for its mild, pleasant climate, comprises one of the country's foremost agricultural regions, its citizens have traditionally felt close to, conducted a lively international trade with, neighboring towns of northern Argentina. Between 1816-1898, the region was part of Argentina, was ceded to Bolivia in exchange for Puna de Atacama.
Tarija boasts South America's second-largest natural gas reserves. Increased gas revenues and foreign direct investment in gas exploration and distribution are fueling growth and turning Tarija into Bolivia's next industrial hub. Political instability at the national level has hindered development of the reserves, as the region has chosen to align with pro-autonomy forces which aim at the devolution of considerable powers away from the central government in favor of the departments. More than 20 different indigenous tribes, ranging in population from 20 persons up to 1500, live in the region; the Guaraní is the largest tribe. Important battles and events related to the 1932-35 Chaco War with Paraguay took place in the department's eastern dry lands. Tarija was the home of Víctor Paz Estenssoro, leader of the 1952 Bolivian Revolution and four-time Constitutional President; the main economic activity is the wine industry. The land and climate are ideal for wine production; the city of Tarija holds an annual Festival of Cheese.
The petroleum industry is important not only for the region but for the country as a whole the gas industry, exported to Argentina and Brazil. The autonomous region of Gran Chaco is from; the languages spoken in the department are Spanish, Quechua and Guaraní.

Bolivia the Plurinational State of Bolivia is a landlocked country located in western-central South America. The capital is Sucre; the largest city and principal industrial center is Santa Cruz de la Sierra, located on the Llanos Orientales a flat region in the east of Bolivia. The sovereign state of Bolivia is a constitutionally unitary state, divided into nine departments, its geography varies from the peaks of the Andes in the West, to the Eastern Lowlands, situated within the Amazon Basin. It is bordered to the north and east by Brazil, to the southeast by Paraguay, to the south by Argentina, to the southwest by Chile, to the northwest by Peru. One-third of the country is within the Andean mountain range. With 1,098,581 km2 of area, Bolivia is the fifth largest country in South America, the 27th largest in the world and the largest landlocked country in the Southern Hemisphere; the country's population, estimated at 11 million, is multiethnic, including Amerindians, Europeans and Africans.
The racial and social segregation that arose from Spanish colonialism has continued to the modern era. Spanish is the official and predominant language, although 36 indigenous languages have official status, of which the most spoken are Guarani and Quechua languages. Before Spanish colonization, the Andean region of Bolivia was part of the Inca Empire, while the northern and eastern lowlands were inhabited by independent tribes. Spanish conquistadors arriving from Cuzco and Asunción took control of the region in the 16th century. During the Spanish colonial period Bolivia was administered by the Royal Audiencia of Charcas. Spain built its empire in large part upon the silver, extracted from Bolivia's mines. After the first call for independence in 1809, 16 years of war followed before the establishment of the Republic, named for Simón Bolívar. Over the course of the 19th and early 20th century Bolivia lost control of several peripheral territories to neighboring countries including the seizure of its coastline by Chile in 1879.
Bolivia remained politically stable until 1971, when Hugo Banzer led a coup d'état which replaced the socialist government of Juan José Torres with a military dictatorship headed by Banzer. Banzer's regime cracked down on leftist and socialist opposition and other forms of dissent, resulting in the torture and deaths of a number of Bolivian citizens. Banzer was ousted in 1978 and returned as the democratically elected president of Bolivia from 1997 to 2001. Modern Bolivia is a charter member of the UN, IMF, NAM, OAS, ACTO, Bank of the South, ALBA and USAN. For over a decade Bolivia has had one of the highest economic growth rates in Latin America, it is a developing country, with a medium ranking in the Human Development Index, a poverty level of 38.6%, one of the lowest crime rates in Latin America. Its main economic activities include agriculture, fishing and manufacturing goods such as textiles, refined metals, refined petroleum. Bolivia is rich in minerals, including tin and lithium. Bolivia is named after Simón Bolívar, a Venezuelan leader in the Spanish American wars of independence.
The leader of Venezuela, Antonio José de Sucre, had been given the option by Bolívar to either unite Charcas with the newly formed Republic of Peru, to unite with the United Provinces of Rio de la Plata, or to formally declare its independence from Spain as a wholly independent state. Sucre opted to create a brand new state and on 6 August 1825, with local support, named it in honor of Simón Bolívar; the original name was Republic of Bolívar. Some days congressman Manuel Martín Cruz proposed: "If from Romulus comes Rome from Bolívar comes Bolivia"; the name was approved by the Republic on 3 October 1825. In 2009, a new constitution changed the country's official name to "Plurinational State of Bolivia" in recognition of the multi-ethnic nature of the country and the enhanced position of Bolivia's indigenous peoples under the new constitution; the region now known as Bolivia had been occupied for over 2,500 years. However, present-day Aymara associate themselves with the ancient civilization of the Tiwanaku culture which had its capital at Tiwanaku, in Western Bolivia.
The capital city of Tiwanaku dates from as early as 1500 BC when it was a small, agriculturally based village. The community grew to urban proportions between AD 600 and AD 800, becoming an important regional power in the southern Andes. According to early estimates, the city covered 6.5 square kilometers at its maximum extent and had between 15,000 and 30,000 inhabitants. In 1996 satellite imaging was used to map the extent of fossilized suka kollus across the three primary valleys of Tiwanaku, arriving at population-carrying capacity estimates of anywhere between 285,000 and 1,482,000 people. Around AD 400, Tiwanaku went from being a locally dominant force to a predatory state. Tiwanaku expanded its reaches into the Yungas and brought its culture and way of life to many other cultures in Peru and Chile. Tiwanaku was not a violent culture in many respects. In order to expand its reach, Tiwanaku exercised great political astuteness, creating colonies, fostering trade agree
