25Jährige

25-Jährige is a German term used to describe people who are 25 years old. In German grammar this noun is formed from the numeral 25 and the noun Jahr, and has gendered forms: der 25-Jährige (masculine singular), die 25-Jährige (feminine singular), and die 25-Jährigen (plural). The spelling "25Jährige" without a hyphen is sometimes seen in informal writing, but "25-Jährige" and "25-Jährigen" are standard in edited texts.

As a demographic category, 25-Jährige represents an early adult age cohort. The size and characteristics of the group depend on birth rates, migration, and mortality in a given country. In many societies, 25-year-olds are transitioning from education to work, achieving financial independence, and forming households. Health, education, and employment patterns for this group are frequently analyzed in demography and economics.

Applications of the concept include market research, public policy, and social science studies that examine labor market outcomes, housing demand, consumption, and health indicators. Because ages are a key axis of analysis, reports often present data specifically for 25-year-olds or for the broader 20–29 age range. The term itself is neutral and descriptive, without a fixed political or cultural stance.
