Sub-replacement fertilitySub-replacement fertility is a total fertility rate (TFR) that (if sustained) leads to each new generation being less populous than the older, previous one in a given area. The United Nations Population Division defines sub-replacement fertility as any rate below approximately 2.1 children born per woman of childbearing age, but the threshold can be as high as 3.4 in some developing countries because of higher mortality rates. Taken globally, the total fertility rate at replacement was 2.33 children per woman in 2003.
Latin AmericaLatin America is a cultural concept denoting the Americas where Romance languages—languages derived from Latin —are predominant. The term was coined in France in the mid-19th century to refer to regions in the Americas that were ruled by the Spanish, Portuguese, and French empires. The term does not have a precise definition, but it is "commonly used to describe South America, Central America, Mexico, and the islands of the Caribbean." In a narrow sense, it refers to Spanish America and Brazil (Portuguese America).
Latin AmericansLatin Americans (Latinoamericanos; Latino-americanos; Latino-américains), sometimes referred to as Latinos, are the citizens of Latin American countries (or people with cultural, ancestral or national origins in Latin America). Latin American countries and their diasporas are multi-ethnic and multi-racial. Latin Americans are a pan-ethnicity consisting of people of different ethnic and national backgrounds. As a result, some Latin Americans do not take their nationality as an ethnicity, but identify themselves with a combination of their nationality, ethnicity and their ancestral origins.
Total fertility rateThe total fertility rate (TFR) of a population is the average number of children that would be born to a female over their lifetime if: they were to experience the exact current age-specific fertility rates (ASFRs) through their lifetime they were to live from birth until the end of their reproductive life. It is obtained by summing the single-year age-specific rates at a given time. , the total fertility rate varied widely across the world, from 0.78 in South Korea to 6.73 in Niger.
ColombiaColombia (kəˈlʌmbiə, -ˈlɒm-; koˈlombja), officially the Republic of Colombia, is a country mostly in South America with insular regions in North America. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments. The Capital District of Bogotá is also the country's largest city hosting the main financial and cultural hub.
Population declinePopulation decline, also known as depopulation, is a reduction in a human population size. Over the long term, stretching from prehistory to the present, Earth's total human population has continued to grow; however, current projections suggest that this long-term trend of steady population growth may be coming to an end. Until the beginning of the Industrial Revolution, the global population grew very slowly, at about 0.04% per year. After about 1800, the growth rate accelerated to a peak of 2.
African diasporaThe global African diaspora is the worldwide collection of communities descended from Native Africans or people from Africa, predominantly in the Americas. The term most commonly refers to the descendants of the native West and Central Africans who were enslaved and shipped to the Americas via the Atlantic slave trade between the 16th and 19th centuries, with their largest populations in the United States, Brazil, and Haiti (in that order).
German diasporaThe German diaspora consists of German people and their descendants who live outside of Germany. The term is used in particular to refer to the aspects of migration of German speakers from Central Europe to different countries around the world. This definition describes the "German" term as a sociolinguistic group as opposed to the national one since the emigrant groups came from different regions with diverse cultural practices and different varieties of German.
Fertility and intelligenceThe relationship between fertility and intelligence has been investigated in many demographic studies. There is evidence that, on a population level, measures of intelligence such as educational attainment and literacy are negatively correlated with fertility rate in some contexts. However, genetic studies have shown no evidence for dysgenic effects in human populations. Theories about dysgenic and eugenic effects in human populations have historically been associated with scientific racism.
ScientistA scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods, it was not until the 19th century that the term scientist came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833.
