What birth years define each generation?

This tool uses widely cited ranges: Silent Generation 1928–1945, Baby Boomers 1946–1964, Gen X 1965–1980, Millennials 1981–1996, Gen Z 1997–2012, Gen Alpha 2013–present. Exact cutoffs vary slightly by source.

Is Gen Z the same as Zoomers?

Yes. "Zoomers" is a colloquial name for Generation Z (born 1997–2012), coined in contrast to Boomers.

What comes after Gen Z?

Generation Alpha (born 2013 onward) follows Gen Z. The cohort is still forming, so the end year is not yet fixed.

Who are Xennials or the Oregon Trail Generation?

Xennials is an informal micro-generation for people born roughly 1977–1983 who straddle Gen X and Millennials. This tool uses the standard major cohorts and does not display micro-generations.

Why do some sources show different year cutoffs?

There is no single official authority on generational boundaries. Pew Research, the U.S. Census Bureau, and various demographers use slightly different ranges. This tool uses Pew Research's most-cited definitions.
