A

No of deaths from the specific disease in a year $$/$$ total deaths from all causes in that year $$\times$$ 100

B

Total No of deaths due to a particular disease $$/$$ Total no of cases due to same disease $$\times$$ 100

C

No of deaths during the year $$/$$ mid-year population $$\times$$ 1000

D

Deaths in January $$\times$$ 12 $$/$$ mid-year population $$\times$$ 100
