Currently, almost two billion persons worldwide, that is 30% of the world population, have access to the Internet (Internet World Stats). These numbers are accurate as of June 30, 2010, and will soon be outdated: access has grown by 445% from 2000. The proportion of users varies by country, being 77% in North America and 58% in Europe, with notable peaks in the Nordic countries, where Denmark and Finland are above 85% and Norway and Sweden are above 90%. Figure 12.1 provides a global view on the proportion of users and growth in use in the last 10 years.
