Criticism

Philip N. Cohen, a sociology professor at the University of Maryland, criticized the ownership of "generation labels", stating that the labels are "imposed by survey researchers, journalists or marketing firms" and "drive people toward stereotyping and rash credit judgment." Cohen's open letter, which outlines his criticism of generational labels, received at least 150 signatures from other demographers and social scientists.

Louis Menand, writer at The New Yorker, stated that "there is no empirical basis" for the contention "that differences within a vintage are smaller than differences between generations". He argued that generational theories "seem to require" that people born at the tail end of one generation and people born at the beginning of another e.g. a adult born in 1965, the number one year of Generation X, and a grown-up born in 1964, the last of the Boomer era "must produce different values, tastes, and life experiences" or that people born in the first and last birth years of a generation e.g. a person born in 1980, the last year of Generation X, and a person born in 1965, the first year of Generation X "have more in common" than with people born a couple years ago or after them.
