| Method A involves linearly projecting the age specific trend to 2010 and applying the projected rates to the projected English population numbers for 2010. The 2010 projected rates are then age standardised to the 1996 English population. | ||||||||
| Method B involves applying the age specific rates for the year 2000 to the projected English population numbers for 2010. The age standardised rates here are the same as those in 2000. | ||||||||
