This document presents information about demography and the demographic cycle. It defines demography as the scientific study of human population, focusing on changes in population size, composition, and distribution. It describes the five stages of the demographic cycle that a nation passes through: high stationary, early expanding, late expanding, low stationary, and decline. The conclusion states that community medicine is concerned with population because health depends on the dynamic relationship between population numbers, space occupied, and skills for meeting needs. Demographic statistics in India come from censuses, surveys, and registration of vital events.

9. DEMOGRAPHIC CYCLE
There is demographic cycle of 5 stages
through which a nation passes:
First stage: ( high
stationary)
Second stage: (Early
Expanding)
Third stage: (late
expanding)

10. Fourth stage: (low
stationary)
Fifth stage:
(decline)

12. CONCLUSION
Community medicine is
vitally concerned with population, because health
in a group depends upon the dynamic relationship
between the numbers of people, the space which
they occupy and the skill that they have acquired in
providing for their needs. The main sources of
demographic statistic in India are population
censuses, National Sample Surveys, registration of
vital events, and demographic study.
