..

• “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
