Yes, the thing is stadiums in those days were massively unsafe and uncomfortabe: cramped all standing sections, no amenities, etc. Over time safety standards improved and so even if stadiums are physically the same size or even bigger, the density is much lower. The biggest football stadium nowadays I believe is Camp Nou, short of 100,000. The new Maracanã seats only 80,000 :p
