Whose income do I include when applying on healthcare.gov?

• disability income insurance
• income protection insurance
• symptoms of cardiovascular disease include

I'm 27, so I can't be included on a parent's health insurance plan. I live with my mom and my aunt, but I get confused when they ask about household income. Do I have to include theirs or are they only asking for mine? When filing taxes, I do this alone (I am not a dependent nor do I claim any dependents.) Should I be shopping for insurance as a household (all three of us) or should we be doing this as individuals? Our jobs do not offer insurance. Thanks in advance for any advice you can offer!
