Generation X is the demographic cohort following the Baby Boomers and preceding Millennials. Researchers and popular media often use the mid-1960s as its starting birth years and the late 1970s as its 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 of Generation X are the children of the Silent Generation and early Baby Boomers; Xers are also often the parents of Millennials and Generation Z.
Baby boomers, often shortened to boomers, are the demographic cohort following the Silent Generation and preceding Generation X. The generation is often defined as people born from 1946 to 1964 during the mid-20th century baby boom. The dates, the demographic context, and the cultural identifiers may vary by country. Most baby boomers are the children of either the Greatest Generation or the Silent Generation, and are often parents of Gen Xers and Millennials.
A generation is all of the people born and living at about the same time, regarded collectively. It also is "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, generation is a structural term, designating the parent–child relationship. In biology, generation also means biogenesis, reproduction, and procreation.
Millennials, also known as Generation 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 older Generation X. In turn Millennials are often the parents of Generation Alpha.
The 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 social generation is generally defined as people born from 1901 to 1927. They were shaped by the Great Depression and were the primary generation composing the enlisted forces in World War II. Most people of the Greatest Generation are the parents of the Silent Generation and Baby Boomers, and, in turn, are the children of the Lost Generation.
The World Values Survey (WVS) is a global research project that explores people's values and beliefs, how they change over time, and what social and political impact they have. Since 1981 a worldwide network of social scientists have conducted representative national surveys as part of WVS in almost 100 countries.
In sociology, postmaterialism is the transformation of individual values from materialist, physical, and economic to new individual values of autonomy and self-expression.
The Silent Generation, also known as the Traditionalist Generation, is the Western demographic cohort following the Greatest Generation and preceding the baby boomers. The 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.
The term new social movements (NSMs) is a theory of social movements that attempts to explain the plethora of new movements that have come up in various western societies roughly since the mid-1960s which are claimed to depart significantly from the conventional social movement paradigm.
A population pyramid or "age-sex pyramid" is a graphical illustration of the distribution of a population by age groups and sex; it typically takes 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 in absolute numbers or as a percentage of the total population. The pyramid 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. Number of people per unit area of land is called population density.
Modernization theory holds that as societies become more economically modernized, wealthier and more educated, their political institutions become increasingly liberal democratic. The "classical" theories of modernization of the 1950s and 1960s, most influentially articulated by Seymour Lipset, drew on sociological analyses of Karl Marx, Emile Durkheim, Max Weber, and Talcott Parsons. Modernization theory was a dominant paradigm in the social sciences in the 1950s and 1960s, and saw a resurgence after 1991, when Francis Fukuyama wrote about the end of the Cold War as confirmation on modernization theory.
Ronald F. Inglehart was an American political scientist specializing in comparative politics. He was director of the World Values Survey, a global network of social scientists who have carried out representative national surveys of the publics of over 100 societies on all six inhabited continents, containing 90 percent of the world's population. The first wave of surveys for this project was carried out in 1981 and the latest wave was completed in 2019. From 2010 Inglehart also was co-director of the Laboratory for Comparative Social Research at the National Research University - Higher School of Economics in Moscow and St Petersburg. This laboratory has carried out surveys in Russia and eight ex-Soviet countries and is training PhD-level students in quantitative cross-national research methods. Inglehart died on 8 May 2021.
Traditional Japanese political values are commonly characterized by a strong community sense and group solidarity and the importance of personal connections and consensus building.
The 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 Western world. 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.
In 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. These blocs are distinguished by similar socio-economic characteristics, who vote and view the world in a similar way. 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.
In Iran, the Burnt Generation is the generation born between roughly 1966 and 1988, having experienced the Iranian Revolution, Iran–Iraq War, and political or social consequences of these such as the Iran hostage crisis, the 1980 Iranian Embassy Siege, the Iranian Cultural Revolution, 1988 executions of political prisoners, the 1989 fatwa against Salman Rushdie, and the Islamic revival, as children, teenagers and later as young adults. These events proved fundamental in deciding the very poor prospects and pessimistic outlook of this generation as they entered the workforce in Iran at the end of the 1980s, and throughout the 1990s.
Self-expression values are part of a core value dimension in the modernization process. Self-expression is a cluster of values that include social tolerance, life satisfaction, public expression and an aspiration to liberty. Ronald Inglehart, the University of Michigan professor who developed the theory of post-materialism, has worked extensively with this concept. The Inglehart–Welzel Cultural Map contrasts self-expression values with survival values, illustrating the changes in values across countries and generations. The idea that the world is moving towards self-expression values was discussed at length in an article in the Economist. Expressing one's personality, emotions, or ideas through art, music, or drama, is a way to reveal oneself to others in a way that is special to them.
Christian Welzel is a German political scientist at the Leuphana University Lueneburg and director of research at the World Values Survey Association. He is known for the model of cultural dimensions which measures emancipative values and secular values.
The Inglehart–Welzel cultural map of the world is a scatter plot created by political scientists Ronald Inglehart and Christian Welzel based on the World Values Survey and European Values Survey. It depicts closely linked cultural values that vary between societies in two predominant dimensions: traditional versus secular-rational values on the vertical y-axis and survival versus self-expression values on the horizontal x-axis. Moving upward on this map reflects the shift from traditional values to secular-rational ones and moving rightward reflects the shift from survival values to self-expression values.
Zillennials is the demographic cohort on the cusp of the Millennial and Generation Z cohorts. Their adjacency between the two generations and limited age set has led to their characterization as a "micro-generation." They are generally the children of younger Baby Boomers and Generation X. Estimates of the U.S. population in this cohort range from 30 million to 48 million.
