A generation is a cohort, not a character
How to read a generation carefully
“Baby Boomer” is a useful cohort label, but it is not an explanation of what an individual believes, remembers or can afford. Start with the birth-year definition, then ask what changed across the cohort’s long span.
State the boundary
Pew Research Center defines Baby Boomers as people born from 1946 through 1964. That boundary is a convention used for analysis, not a natural dividing line. When comparing studies, copy each source’s definition instead of assuming every researcher uses the same years.

Separate age from era
A person’s circumstances can reflect their age, the period they live through, and experiences tied to their birth cohort. A pattern observed in older adults today does not automatically show a lifelong Boomer trait. Compare data across time and cohorts before making that claim.
Read population estimates precisely
Pew’s January 2026 analysis uses U.S. Census Bureau 2023 population projections and notes that the oldest Boomers turn 80 in 2026. The Census cohort report counts people in the U.S. population born in those years, including people born elsewhere. Keep the geography and method attached to any total.

Leave room for different lives
A cohort contains differences in race, place, income, health, migration and family history. Use group-level data to frame questions, then use individual testimony and local evidence to show variation. A photograph of older people can illustrate age; it cannot stand in for a generation.
