Millennials. There are old ones, young ones, ones who aren't married (and ones who are), urban ones, suburban ones. The list goes on. Just like with every labeled age group before (Generation X, Baby Boomers, the Silent Generation), it's virtually impossible to fit this generation perfectly into one, single entity. "Millennial" is a marketing misnomer if unilateral marketing strategies are applied to the lot.
But there are commonalities that can help marketers connect with younger buyers—across lifestyles and sensibilities.
