-        The Data Grid is core data that is essential for preparedness and emergency response. For each sub-category, we assess whether a relevant dataset is 'available'. To be considered available, relevant data should be sub-national, in a commonly used format and up-to-date. Data that is relevant but not up-to-date will be included but marked as 'not up-to-date'. Data that is missing will be marked as 'unavailable'
