Being older and married without kids is only marginally better, from the advertisers perspective, oddly enough. My sweetie and I have all the toasters and tvs and gadgets we need, and are no longer looking to validate our existence to others by buying new ... shit. With no kids to drive the urge to spend, the advertisers just can't get traction with us. And, if the advertisers aren't talking to you, then you don't exist.
I'm single but largely in the same place. I don't need a new widget. Making the world even more difficult for advertisers, if I do need a new widget, I'm going to research it, look for alternatives, read reviews and only purchase it when I'm convinced it meets my needs. Some advertising gets through (you know maybe it IS time to replace my ancient, extremely loud vacuum cleaner), but it's tempered by needing to be useful and being the best at meeting my needs.
