What is the most connected country in the world? Interestingly, it seems that Finland has a very heavy penetration rate for broadband Internet, with an estimated 96% of Finns online. Under age 40, the percentage of those who make use of the Internet is at 100%, and the number of mobile phones exceed the number of inhabitants. While Finlands population is only 5.2 million, that level of connectivity is impressive. That puts them ahead of the U.S. and Britain, though recent figures haven't been published for countries around the world.
