Generational cohort theory refers to the distinct generations that are created by common social experiences. These generations include veterans (born 1925–1944), baby boomers (born 1945–1964), generation X (born 1965–1981), and generation Y (born 1982–2000). While veterans are characterized by their honesty and loyalty, baby boomers are seen as independent and optimistic. Generation X are typically cynical and pessimistic, and generation Y are known for their confident and optimistic personalities. This entry describes multigenerational differences in motivation, politics, education, family views, health behaviors, work ethic, and religion.
