Diabetes has become a common condition. One that affects the lives of millions worldwide. The International Diabetes Federation estimates that there are as many as 387 million Type 2 diabetic people in the world and that is not counting atleast half that number who are probably in the undiagnosed stage.
It is now common knowledge 6 out of every 100 people in the UK have diabetes. According to UK's National Diabetes Audit, there are 700 new diabetes diagnosis made every day. That means by the time you finish reading this article, a dozen people in the UK have probably got news of their diagnosis.

Based on the report of the National Diabetes Audit (NDA) in England and Wales and the Scottish Diabetes Survey the following stat is apparent. As expected, the condition is mostly seen in the age group 40-70.
Age England & Wales Scotland 0 to 9 0.21% 0.25% 10 to 19 0.94% 1.18% 20 to 29 1.69% 2.06% 30 to 39 3.76% 3.53% 40 to 49 10.67% 9.5% 50 to 59 19.3% 19.09% 60 to 69 26.20% 26.46%
Surveys indicate that men have a greater propensity to diabetes - In the UK, 56% of all diabetics are men and remaining 44% are women.
Type 1 vs Type 2
Type 2 is the more common of the two by a long margin. In general, 90% of adult diabetics are Type 2 and only 10% are type 1.
However in young people below 19, the reverse is true - Type 1 diabetes accounts for about 95% of the diagnosed cases. Children with diabetes exhibit distinct lack of beta cells which makes the body incapable of producing insulin - a marked feature of Type 1. Within that age group Type 2 is very rare indeed.
The prevalence of Type 1 diabetes in children below 15 years of age is 187.7 cases per 100,000. Its rare, but not THAT rare.
World Statistic 
Around 387 million people the world over are estimated to have diabetes. This number is expected to rise to half a billion in the next 20 years. The disease seems to affect the lower income countries more.
One out of 2 people don't even know they have diabetes. Majority of people living with diabetes are those who are between 40 and 60 years of age.
It is estimated that close to 50% of people are living with undiagnosed diabetes. Every 7 seconds a person dies from diabetes and the global health expenditure in 2014 to treat diabetes is estimated to be a whopping 612 billion dollars. In 2013 over 79,000 children were diagnosed with Type 1 diabetes.
The prevalence rate of Juvenile Type 1 diabetes is highest in Europe. The highest occurrence of diabetes is seen in the western pacific region (China, Japan, Australia, Vietnam and others)
