Dummy with multiple options

Hi! I need to create a dummy variable for several group ages. I have the following set (of ages)
15-24
25-35
35-44
45-54
55-64
>65
I would like to make them "1" if they are in the age category 15-24 OR 25-35 OR 35-44, and 0 if not. How can I do that?
Thank you so much!

Celeste
