Wrong superset. Take the population of the top 25 and add it together.
The figure that matters is the price of a one-way U-Haul rental. Price to go from Dallas to SF, around $400. Price to go from Dallas to SF, around $1300.
The Top 25 is going to include all the high-population Eastern states, plus California. Still 5 mil. out of a healthy three-digit number.
