Collected as part of a community survey. Possible survey question could be: ' have you experienced physical violence, such as being hit or beaten by someone within the last 30 days' If the answer is yes a follow up question should be asked to identify whether this was by someone from within the household or someone outside. This helps to differentiate between levels of domestic violence and violence taking place in the wider community.
For analysis a simpe percentage should be taken of the number of respondents reporting that they have experienced violence. Care should be taken in deciding whether this percentage applies to just those surveyed or whther it can be ascribed to the population as a whole. This will depend on the design of the survey and whether it was a represnetative sample of the population.
