There is an argument that psychographics are more important than demographics. In other words, it often is argued, a consumer’s personality, values, opinions, attitudes, interests and lifestyles matter more than where a consumer lives, how much money a consumer makes, education attainment or age.
In actuality, both probably matter to some extent, though targeting relies more on psychographics than demographics.
Still, we might note that generations emerge in different technology contexts. The “Silent” generation grew up in the era of radio. The “Baby Boomers” grew up in the era of television. “Gen X” grew up in the personal computer era. “Millennials” grew up in the Internet and mobile era.
