Tables 18 [a] and [b] provide a breakdown [by Diabetes Type respectively] of Age by Duration of Diabetes (where all three data items were available for analysis).
This shows the majority of individuals who were stated to be Type 1 were in the 20-29 decade age range, [23.7%], with 19.8% [of all Type 1 individuals], in the 30-39 age group.
For Type 2, the predominant age decades of individuals were 60-69 [33.0%], thence 70-79 and 50-59 [24.9% & 21.2% respectively].

The resulting integer would be 0 if diagnosed in 2011, and 1 if diagnosed in 2010 [and in fact a maximum of 18 Mths – 1 Jan ’10 diagnosis to 30 Jun ’11 survey]. Duration 18 Mths-5 Years is thus a minimum 18 Mths {Dec ’09 diagnosis to Jun ’11 survey} to 5 years 06-11].
In regards to duration of Type 1, 7.0% were “newly diagnosed” (duration <=18 Months), with 13.5% 18 Months-5 Years duration, and 15.9% 6-10 Years - the remainder being 15.5% 11-15 Years and 48.1% 16-plus Years. For Type 2 there were 9.1% “newly diagnosed”, the remainder relatively equally spread across the diabetes duration groups, apart from the largest group, 34.0% having a diabetes duration of 16 plus Years.
