I found that 66% of the people that answered my survey have siblings and the other 33% didn't have siblings. I can possibly conduct another survey to find out who exactly those 66% were by asking them to put their names this time. Another question on the survey that I asked was "What would you do to help your siblings or parents?" and was answered by almost the same answer each time; Anything they needed help with or anything because I love them. The people that answered my survey had no siblings with any disabilities and the repeated answers were no or nope.
