Demographic surveillance system
Demographic Surveillance System
A Demographic Surveillance System (DSS) (pronunciation: /dɪˈmɒɡrəfɪk sɜːˈveɪləns ˈsɪstəm/) is a framework used to monitor the demographic dynamics of a population in a defined geographic area. It is a crucial tool in epidemiology and public health research, providing valuable data for health planning and policy development.
Etymology
The term "Demographic Surveillance System" is derived from three words. "Demographic" comes from the Greek words demos (people) and grapho (I write), referring to the statistical study of populations. "Surveillance" is from the French surveiller, meaning to watch over. "System" is from the Latin systema, meaning a whole compounded of several parts or members.
Function
A DSS collects data on births, deaths, migration patterns, and health indicators in a population over time. This information is used to understand changes in population dynamics and health trends, which can inform health policy and planning.
