WDemography is the statistical study of populations, especially human beings.
WThe Strauss–Howe generational theory, devised by William Strauss and Neil Howe, describes a theorized recurring generation cycle in American history and global history. According to the theory, historical events are associated with recurring generational personas (archetypes). Each generational persona unleashes a new era lasting around 20–25 years, in which a new social, political, and economic climate (mood) exists. They are part of a larger cyclical "saeculum". The theory states that a crisis recurs in American history after every saeculum, which is followed by a recovery (high). During this recovery, institutions and communitarian values are strong. Ultimately, succeeding generational archetypes attack and weaken institutions in the name of autonomy and individualism, which eventually creates a tumultuous political environment that ripens conditions for another crisis.
WBaby boomers are the demographic cohort following the Silent Generation and preceding Generation X. The generation is generally defined as people born from 1946 to 1964, during the post–World War II baby boom. The term is also used outside the United States, but the dates, the demographic context, and the cultural identifiers may vary. The baby boom has been described variously as a "shockwave" and as "the pig in the python". Most baby boomers are children of either the Greatest Generation or the Silent Generation, and are often parents of late Gen Xers and Millennials. Late baby boomers can also be the parents of gen-zer’s.

WGeneration Z, colloquially also known as zoomers, is the demographic cohort succeeding Millennials and preceding Generation Alpha. Researchers and popular media use the mid-to-late 1990s as starting birth years and the early 2010s as ending birth years. Most members of Generation Z are children of Generation X.
WA city proper is the geographical area contained within city limits. The term proper is not exclusive to cities; it can describe the geographical area within the boundaries of any given locality. The United Nations defines the term as "the single political jurisdiction which contains the historical city centre."
WIn political science and sociology, a cleavage is a historically determined social or cultural line which divides citizens within a society into groups with differing political interests, resulting in political conflict among these groups. Social or cultural cleavages thus become political cleavages once they get politicized as such. Cleavage theory accordingly argues that political cleavages predominantly determine a country's party system as well as the individual voting behavior of citizens, dividing them into voting blocs. It is distinct from other common political theories on voting behavior in the sense that it focuses on aggregate and structural patterns instead of individual voting behaviors.
WDemic diffusion, as opposed to trans-cultural diffusion, is a demographic term referring to a migratory model, developed by Luigi Luca Cavalli-Sforza, of population diffusion into and across an area that had been previously uninhabited by that group, possibly, but not necessarily, displacing, replacing, or intermixing with an existing population.
WDemographic engineering is deliberate effort to shift the ethnic balance of an area, especially when undertaken to create ethnically homogeneous populations. Demographic engineering ranges from falsification of census results, redrawing borders, differential natalism to change birth rates of certain population groups, targeting disfavored groups with voluntary or coerced emigration, and population transfer and resettlement with members of the favored group. At an extreme, demographic engineering is undertaken through genocide.
WDemographic window is defined to be that period of time in a nation's demographic evolution when the proportion of population of working age group is particularly prominent. This occurs when the demographic architecture of a population becomes younger and the percentage of people able to work reaches its height. Typically, the demographic window of opportunity lasts for 30–40 years depending upon the country. Because of the mechanical link between fertility levels and age structures, the timing and duration of this period is closely associated to those of fertility decline: when birth rates fall, the age pyramid first shrinks with gradually lower proportions of young population and the dependency ratio decreases as is happening in various parts of East Asia over several decades. After a few decades, low fertility however causes the population to get older and the growing proportion of elderly people inflates again the dependency ratio as is observed in present-day Europe.
WObtaining precise numbers on the demographics of sexual orientation is difficult for a variety of reasons, including the nature of the research questions.
WThe term digital native describes a young person who has grown up in the digital age, in close contact with computers, the Internet, and video game consoles, and later mobile phones, social media, and tablets. The term is often used to refer to millennials, Generation Z, and Generation Alpha; the latter two are sometimes described as distinct "neo-digital natives", "true" digital natives, or "digital integrators".
WDorchester applied first to the township, the name honours Sir Guy Carleton, Lord Dorchester (1724-1808). It was changed from Dorchester Station on May 3, 1961. Dorchester is the residential and commercial core of the municipality of Thames Centre, in Southwestern Ontario, Canada, a few kilometres directly east of the city of London. According to the Canada 2016 Census, the town has a population of 3,911.

WA generation is "all of the people born and living at about the same time, regarded collectively." It can also be described as, "the average period, generally considered to be about 20–30 years, during which children are born and grow up, become adults, and begin to have children." In kinship terminology, it is a structural term designating the parent-child relationship. It is known as biogenesis, reproduction, or procreation in the biological sciences.
WGeneration Alpha is the demographic cohort succeeding Generation Z. Researchers and popular media use the early 2010s as starting birth years and the mid-2020s as ending birth years. Named after the first letter in the Greek alphabet, Generation Alpha is the first to be born entirely in the 21st century. Most members of Generation Alpha are the children of Millennials.
WGeneration X is the demographic cohort following the baby boomers and preceding the millennials. Researchers and popular media use the early-to-mid-1960s as starting birth years and the late 1970s to early 1980s as ending birth years, with the generation being generally defined as people born from 1965 to 1980. By this definition and U.S. Census data, there are 65.2 million Gen Xers in the United States as of 2019. Most members of Generation X are the children of the Silent Generation and early boomers; Xers are also often the parents of millennials and Generation Z.
WGeneration Z, colloquially also known as zoomers, is the demographic cohort succeeding Millennials and preceding Generation Alpha. Researchers and popular media use the mid-to-late 1990s as starting birth years and the early 2010s as ending birth years. Most members of Generation Z are children of Generation X.
WThe Silent Generation is the demographic cohort following the Greatest Generation and preceding the Baby Boomers. The Silent Generation is generally defined as people born from 1928 to 1945. By this definition and U.S. Census data, there were 23 million Silents in the United States as of 2019.

WThe Greatest Generation, also known as the G.I. Generation and the World War II generation, is the demographic cohort following the Lost Generation and preceding the Silent Generation. The generation is generally defined as people born from 1901 to 1927. They were shaped by the Great Depression and were the primary participants in World War II.
WGeneration Z, colloquially also known as zoomers, is the demographic cohort succeeding Millennials and preceding Generation Alpha.

WIncome and fertility is the association between monetary gain on one hand, and the tendency to produce offspring on the other. There is generally an inverse correlation between income and the total fertility rate within and between nations. The higher the degree of education and GDP per capita of a human population, subpopulation or social stratum, the fewer children are born in any developed country. In a 1974 United Nations population conference in Bucharest, Karan Singh, a former minister of population in India, illustrated this trend by stating "Development is the best contraceptive."
WJudenfrei and judenrein are terms of Nazi origin to designate an area that has been "cleansed" of Jews during The Holocaust. While judenfrei refers merely to "freeing" an area of all of its Jewish inhabitants, the term judenrein has the stronger connotation that any trace of Jewish blood had been removed as an alleged impurity in the minds of the criminal perpetrators. These terms of racial discrimination and racial abuse are intrinsic to Nazi anti-Semitism and were used by the Nazis in Germany before World War II and in occupied countries such as Poland in 1939. Judenfrei describes the local Jewish population having been removed from a town, region, or country by forced evacuation during the Holocaust, though many Jews were hidden by local people. Removal methods included forced re-housing in Nazi ghettos especially in eastern Europe, and forced removal or Resettlement to the East by German troops, often to their deaths. Most Jews were identified from late 1941 by the Yellow badge as a result of pressure from Joseph Goebbels and Heinrich Himmler.

WThe Lost Generation was the social generational cohort that was in early adulthood during World War I. "Lost" in this context refers to the "disoriented, wandering, directionless" spirit of many of the war's survivors in the early postwar period. The term is also particularly used to refer to a group of American expatriate writers living in Paris during the 1920s. Gertrude Stein is credited with coining the term, and it was subsequently popularized by Ernest Hemingway who used it in the epigraph for his 1926 novel The Sun Also Rises: "You are all a lost generation".
WA metropolis is a large city or conurbation which is a significant economic, political, and cultural center for a country or region, and an important hub for regional or international connections, commerce, and communications. The term is Ancient Greek (μητρόπολις) and means the "mother city" of a colony, that is, the city which sent out settlers. This was later generalized to a city regarded as a center of a specified activity, or any large, important city in a nation.
WMillennials, also known as Generation Y or Gen Y, are the demographic cohort following Generation X and preceding Generation Z. Researchers and popular media use the early 1980s as starting birth years and the mid-1990s to early 2000s as ending birth years, with the generation typically being defined as people born from 1981 to 1996. Most millennials are the children of baby boomers and early Gen Xers; Millennials are often the parents of Generation Alpha.

WNEET, an acronym for "Not in Education, Employment, or Training", refers to a person who is unemployed and not receiving an education or vocational training. The classification originated in the United Kingdom in the late 1990s, and its use has spread, in varying degrees, to other countries and regions, including Japan, South Korea, China, Taiwan, Canada and the United States. The NEET category includes the unemployed, as well as individuals outside the labour force. It is usually age-bounded to exclude people in old-age retirement.
WNet café refugees , also known as cyber-homeless , are a class of homeless people in Japan who do not own or rent a residence and sleep in 24-hour Internet cafés or manga cafés. Although such cafés originally provided only Internet services, some have expanded their services to include food, drink, and showers. The term was coined in 2007 by a Nippon News Network documentary show NNN Document. The net café refugee trend has seen large numbers of people using them as their homes. The shifting definition of the industry partly reflects the dark side of Japanese economy, whose precarity has been noted since the downfall of the national economy that has lasted for decades.
WGeneration Z, colloquially also known as zoomers, is the demographic cohort succeeding Millennials and preceding Generation Alpha.

WThe concept of Global North and Global South is used to describe a grouping of countries along socio-economic and political characteristics. The Global South is a term often used to identify lower-income countries on one side of the so-called divide, the other side being the countries of the Global North. As such, the term does not inherently refer to a geographical south; for example, most of the Global South is geographically within the Northern Hemisphere.

WThe population of the Byzantine Empire encompassed all ethnic and tribal groups living there, such as Byzantine Greeks, Khazars, Armenians, Slavs, Goths, Arabs, Illyrians, Thracians and other groups. It fluctuated throughout the state's millennial history. The reign of the Emperor Justinian I in the mid-sixth century was the high point of the empire's expansion; however, the arrival of plague in 541 and its subsequent recurrences caused a severe depletion of the population. After the reign of Emperor Heraclius and the loss of the empire's overseas territories, Byzantium was limited to the Balkans and Anatolia. When the empire began to recover after a series of conflicts in the 8th century and its territories stabilized, its population began to recover. By the end of the 8th century the population of the empire was around 7,000,000, a figure that climbed to over 12,000,000 people by 1025. The numbers began falling steadily to 9,000,000 people at 1204 and even lower to 5,000,000 people at 1282 with the arrival of the Turks.
WA population pyramid or "age-sex pyramid" is a graphical illustration of the distribution of a population by age groups and sex; it typically forms the shape of a pyramid when the population is growing. Males are usually shown on the left and females on the right, and they may be measured by count or as a percentage of the total population. This tool can be used to visualize the age of a particular population. It is also used in ecology to determine the overall age distribution of a population; an indication of the reproductive capabilities and likelihood of the continuation of a species.
WThe middle of the 20th century was marked by a significant and persistent increase in fertility rates in many countries of the world, especially in the West. The term baby boom is often used to refer to this particular boom, generally considered to have started immediately after World War II, although some demographers place it earlier or during the war. This terminology led to those born during this baby boom being nicknamed the baby boomer generation.

WThe technology adoption lifecycle is a sociological model that describes the adoption or acceptance of a new product or innovation, according to the demographic and psychological characteristics of defined adopter groups. The process of adoption over time is typically illustrated as a classical normal distribution or "bell curve". The model indicates that the first group of people to use a new product is called "innovators", followed by "early adopters". Next come the early majority and late majority, and the last group to eventually adopt a product are called "Laggards" or "phobics." For example, a phobic may only use a cloud service when it is the only remaining method of performing a required task, but the phobic may not have an in-depth technical knowledge of how to use the service.
