• “Demo” means “the people” and “graphy” means “measurement”.
• (Demos = population, Graphy = picture
Importance of Demographic data Health status of a community depends upon
the dynamic relationship between number of people, their composition& distribution
Planning of health services can be guided by demographic variables, for example: How many health units do we need? How to distribute them in the community in order to be accessible to the target population? What type of manpower is needed?
The elements of demography Size: increase or decrease
Composition: sex and age group
Distribution: territory
