title: Population crowding and death rates due to heart disease.
abstract: Based upon the methodology of earlier research on death rates due to malignant neoplasms reported in this journal, this paper examines the relations between select social morphological factors of population size and density and rates of deaths due to heart disease. This study supports the findings of that earlier paper: populations having a stable morphological structure have a negative relation with death rates; populations experiencing a change in morphology, particularly an increase in the number of persons per housing unit, have a positive relation with mortality rates. An human ecological perspective is introduced to conceptualize the researches.
