Assuming you're in Europe, we go by decades. Ex., we say "in the 60s", "in the 90s", etc. In the States they use "baby boomers", "generation x", "millennials"

Assuming you're in Europe, we go by decades. Ex., we say "in the 60s", "in the 90s", etc. In the States they use "baby boomers", "generation x", "millennials" more, but it's the same thing. It's all based on the postwar period (WWII, generally).
