For an application where you would expect shared spaces for kitchen/bath/etc, and a trade-off of comfort vs capacity, it is. It is higher than other family shelters. Which could be unused space, or perhaps colocated adminstration, or whatever. It wasn't a complaint, just an observation.
For a comparison, at my university dorms its roughly 65 square feet per person.
Do you mean that your room is roughly 10'x13', shared with one roommate? If so, you're not comparing apples to apples. Amazon's number is derived from the entire building (including common hallways, stairs, bathrooms, and other spaces). Also, while a dorm room allocating 65 sqft per person might fit a loft bed, desk, and a student's possessions, that's not convenient for a family shelter.
