Advanced economies account for the bulk of global insurance. With premium income of $1.62 trillion, Europe was the most important region in 2010, followed by North America $1.409 trillion and Asia $1.161 trillion. Europe has however seen a decline in premium income during the year in contrast to the growth seen in North America and Asia. The top four countries generated more than a half of premiums. The United States and Japan alone accounted for 40% of world insurance, much higher than their 7% share of the global population. Emerging economies accounted for over 85% of the world's population but only around 15% of premiums. Their markets are however growing at a quicker pace. The country expected to have the biggest impact on the insurance share distribution across the world is China. According to Sam Radwan of ENHANCE International LLC, low premium penetration (insurance premium as a % of GDP), an ageing population and the largest car market in terms of new sales, premium growth has averaged 15–20% in the past five years, and China is expected to be the largest insurance market in the next decade or two.
Collision coverage has a deductible, which is the amount you pay before your coverage helps pay for your claim. You can typically choose the amount of your deductible when you buy coverage. So, if you choose a $1,000 deductible and your car is later damaged in a covered accident, you'd have to pay $1,000 toward repair costs. Your collision coverage would help pay the rest, up to your coverage limit.
