In recent years, we have witnessed significant shifts in population trends across various generations. Today, Generations Z and Alpha dominate the global population, each making up 23%. However, as we look ahead to 2035, changes in population distribution highlight the aging of older generations and the rise of younger ones.

Builders (Born before 1946)
The Builders generation, born before 1946, consists of individuals aged 80 and above. They make up only 3% of the current population. However, by 2035, their share is projected to drop even further to 0.4%, reflecting the natural aging process and lower life expectancy of this cohort.
Boomers (1946-1964)
Baby Boomers, born between 1946 and 1964, currently account for 13% of the population. This generation played a pivotal role in shaping modern economies and societies. Their population share is expected to decline to 8% by 2035.
Global Workforce Change by Generation: Current and Projected 2035
Generation X (1965-1979)
Generation X comprises individuals aged 46 to 60, making up 17% of the population. While this generation remains a significant contributor to society and the workforce, their share is projected to decline slightly to 14% by 2035.
Generation Y (1980-1994) (Millennials)
Millennials, born between 1980 and 1994, are a prominent generation today. They account for 21% of the population in 2025. Known for their adaptability and tech-savvy nature, their population share is expected to decrease marginally to 19% in the next decade.
Generation Z (1995-2009)
Generation Z, born between 1995 and 2009, represents the largest segment of the population today. This generation currently represents 23% of the global population. However, their share is projected to decrease slightly to 20% by 2035 as Gen Alpha and Gen Beta take on larger roles in society.
Gen Alpha (2010-2024)
Gen Alpha, which comprises individuals aged 15 and younger, is the youngest generation in 2025. They make up 23% of the population today, and this percentage is projected to remain stable at 23% by 2035.
Gen Beta (2025-2039)
Gen Beta refers to those who will be born between 2025 and 2039. However, by 2035, they are projected to make up 16% of the population. This generation will emerge as a driving force in future decades, shaped by the rapid technological and societal changes of today.
In summary, currently, Generations Z and Alpha dominate, but the future will see the rise of Gen Beta as they begin to make their mark. The most prominent trend in the data is the steady growth of younger generations, with Gen Alpha maintaining its significant 23% share even in 2035.
