"The paper presents the problem of mortality in the Lodz area and the city of Lodz in 1993. The basis for this description is comparisons across voivodeships, and these between large and medium-sized cities in Poland. The comparisons were made allowing for the basic demographic features such as sex and age of the dead. Levels of mortality were identified for voivodeships and cities using fractional death rates for five year age groups, with the deaths among infants treated as a separate group."
