How Does Knowing Age Ranges and Generational Info Help With Marketing Strategy?

If you understand customer demographics and how it fits into your small business you can truly make some great leaps in progress with your marketing plan!

I thought a real world example might be helpful for understanding how this all works!

A few months ago I started writing about dementia on my Artsy Fartsy blog when we moved my Mother In Law in with us. She hits the very last part of the silent generation being born in 1945, but she is very much a product of the consumption of Baby Boomers (shopping is her life!)

But is she my target demographic for marketing (getting website views, selling affiliate products and building an email list?) NO! My target demographic is the Sandwich Generation, younger Baby Boomers and Gen Xers who are now stuck with caring for their aging parents WHILE raising their own children. 

Baby Boomers are a consumption generation, taking advantage of their large buying numbers and desire to be seen as “cool and hip”. 

Gen X-ers are a practical bunch who grew up before the internet and who took care of themselves at home after school as latchkey kids while their moms went back into the workforce. 

So with two different demographics I can target in my marketing efforts, I need to make sure to create content that would appeal to both of those models. Posts about products to help take care of elderly people AND practical tips for how to do it all yourself. 

The great thing is that by knowing how each of the generations responds to marketing, I can make sure that I am creating content (blog posts, graphics, social media posts) that will be interesting to both groups.

The numbers and charts provided are for marketing purposes only and should not be taken as gospel! We are waiting for updated data from the next census to revise percentages. 

Age Ranges FAQ

Since I have had this post for a while, I have gotten different questions over the years as I update the post so here are some of them!

What's After Gen Z?

Generation Alpha is a suggested term that could come after Gen Z. It is thought to be Mid 2010s to the present.

That said, I haven't seen it wide use and they are really kind of young to have any impact on sales at this time.
