World's Most Crowded Football Stadium (Rio de Janeiro, Brazil)

World's Most Crowded Street (Shibuya, Tokyo, Japan)
With 2.5 million people a day, there's no doubt Tokyo's Shibuya is the busiest intersection in the world. No matter what time you go, the crossing is always busy. During the day, in the middle of night, at dusk – the amount of people is always consistent. It must be quite exciting when the green light goes on and you see the thousands moving in your direction.
World's Most Crowded Prison (Kresty Prison, St. Petersburg, Russia)
Russia's prisons have a reputation for being the most overcrowded on earth, especially Kresty Prison in St. Petersburg. The official capacity is set at 3,000, but the actual population is always at least 10,000. Each prisoner is also said to only be allowed 4 square meters of space each and 15 minutes a week (a week!) to shower. In summer 2006 Vladimir Putin announced that the prison would be relocated to a new facility in the Kolpinsky District on the outskirts of Saint Petersburg. After the relocation is complete the Kresty building will be sold at auction. It is anticipated that the prison building will be transferred into a hotel-entertainment complex.
World's Most Crowded Train (India)
A lot of people assume that Japan has the world's most crowded trains. Apparently that's not the case. On a episode of a Japanese TV show, "Itte Q," a reporter was sent to India so she could experience what may be the "world's most crowded train". They wanted to see if she could read a newspaper on the train, but it proved extremely difficult.

World's Most Crowded Subway Station (Moscow, Russia)
This image was taken in a typical day in Moscow city subway. Not every station is like this but there are some narrow places so when the peak traffic happens people have to move like that.
Europe's Most Crowded Country (England)
The number of people living in England has overtaken the population density of Holland, which has traditionally been the most densely-populated major nation on the continent. The count, which has been attributed to higher levels of immigration, shows England has 395 people per square kilometre. China is still the most crowded country in the world.
