It is defined as, the number of death (from all causes) per 1000 estimated midyear population in one year, in a given place.              

No of deaths during the year

---------------------------------------------------------1000

Number of death related to pregnancy during given time in A given area

----------------------------------------------------------------------------------------*1000

Number of live birth reported during the same time interval in the same area
