Nope. I had a room to myself my senior year of high school when my sister left for college. Didn't have a room to myself again until I graduated from college. I continued to have roommates until I married at 29, but at that point we had enough money to prioritize having our own bedrooms.
I was considered very lucky because my bedroom growing up was specifically larger and had room for two beds, etc. It was a typical three bedroom ranch, but we bought from someone who had it built for the same family configuration of 3 kids sharing two bedrooms. I had friends who had 3 girls in a small bedroom with a single door closet to share, while their brother got his own room. It was just the way it was.
