"There Are More People Living in This Circle Than Outside It"

The Daily Mail published a load of fascinating maps this week.
My favorite was this one:
Included in the article is another map showing the average age at which people say (whether they are telling the truth or not) they first have sex; the average age is far higher in exactly that very populous region. Cause, effect, who knows?
Musing #2, the Philippines typhoon was a tragedy and 10,000 people died. Using the figures from here, about 6,000 babies are born every day in the Philippines.
Musing #3, a far worse natural town planning disaster was the Boxing Day tsunami which killed/drowned about 200,000 people in Indonesia. According to the UN, about 12,000 babies are born every day in Indonesia, which means that the population would have replenished itself within two or three weeks.
