While this analysis is useful in explaining the complex nature of trafficking, the factors that play a role in trafficking are actually interdependent and interconnected. Some factors, such as military conflict, do not fit neatly into either the "demand" or "supply" side of trafficking, but nevertheless have contributed to this problem in some regions. For example, internal conflicts force people to leave their home country, which may encourage trafficking across borders. At the same time, an increase in military personnel in a specific region also increases the "demand" for women to be brought from outside to work in the commercial sex industry.
