Millennials (often called Generation Y) are the cohort that grew up alongside the internet, smartphones, and social media—and then entered adulthood during a period defined by rapid technology change, major economic disruption, and shifting norms around work, family, and housing.
This page focuses on the most verifiable, frequently cited millennial statistics—population size, labor force share, digital access, and housing—using primary research organizations and major industry reports. Older “snapshot” stats are kept only when clearly labeled by year.

Who Counts as a Millennial?
Generational definitions vary by source, but Pew Research Center’s widely used definition sets Millennials as those born from 1981 to 1996. That puts most Millennials in their late 20s through mid-40s in the mid-2020s.
How Many Millennials Are in the U.S.?
Millennial population estimates depend on the exact cutoff dates and the dataset year. Two commonly cited Census-based snapshots are:
- 72.1 million Millennials as of July 1, 2019 (Pew analysis of Census population estimates).
- 74.2 million Millennials in a newer Census-based estimate (reported in 2025), equal to 21.8% of the U.S. population.

Living with parents
Living arrangements have shifted too. Pew Research Center reported that in 2023, 18% of adults ages 25–34 lived in a parent’s home (with higher rates for men than women).

Technology & Mobile Access
While “millennials are glued to phones” is an easy stereotype, the more durable statistic is that smartphone ownership is now mainstream across adults. Pew’s mobile fact sheet shows 91% of U.S. adults own a smartphone (2025). Pew also notes a subset of adults are “smartphone dependent” (smartphone but no home broadband), highlighting that phones are still the primary gateway to the internet for some households.
