This study analyses the relationship between war and population. The impact of the growth and decline of population on important types of warfare--great power, small power, civil war as well as terrorism--is illustrated, with the objective in each case to be descriptive of risk. I find that population change has a significant impact on each, with the greatest causal impact on small power conflicts, civil war and upon terrorism. I conclude with some reasons for guarded optimism about the incorporation of population as a component of analysis in the discipline of international studies, and for the potential to devise new solutions to prevent conflict.
Considering population and war: a critical and neglected aspect of conflict studies.
