6 Factors well organised into a logical format. Detailed explanations' including an understanding of how the reasons might effect different groups unequally.e.g. The fact that a country was at war would cause an increase in the death rate that would mainly affect adult males.

7 A very detailed response that includes a variety of factors organised in a logical format. Full explanations with real world examples.e.g. Disease will cause the death rate to up, however it will not effect all age groups equally, the elderly and the young are more likely to die.
