Advanced economies account for the bulk of global insurance. With premium income of $1,217 billion in 2004, North America was the most important region, followed by the EU (at $1,198 billion) and Japan (at $492 billion). The top four countries accounted for nearly two-thirds of premiums in 2004. The United States and Japan alone accounted for a half of world insurance premiums, much higher than their 7% share of the global population. Emerging markets accounted for over 85% of the world’s population but generated only 10% of premiums. The volume of UK insurance business totaled $295 billion in 2004 or 9.1% of global premiums.
