The civil registration system in India has a lot to be improved and would require a huge effort and time. A need for having an alternate source of such information was felt. The Government of India, in the late 1960s, initiated the Sample Registration System (SRS).
SRS aims to provide reliable estimates of birth and death rates for the States and also at All India level. Following features of SRS ensure the completeness of vital events reporting:
1. A representative sample of the population is covered and NOT the WHOLE population

Unlike Census, ‘’Registration of vital events’’ maintains a continuous record of demographic trends.
Definition (UN): ‘legal registration, statistical recording and reporting of the occurrence of and the collection, compilation, presentation, analysis and distribution of statistics pertaining to vital events’
Vital events include:
a. Live births
b. Deaths
c. Fetal deaths
d. Marriage
e. Divorce
f. Adoptions
g. Legitimations
h. Recognitions
i. Annulments and
j. Legal separations

Definition of Census (UN): ‘The total process of collecting, compiling and publishing demographic, economic and social data pertaining at a specified time or times, to ALL persons in a country or delimited territory’.
It is massive undertaking to contact every member of the population in a given time and collect a variety of information
It needs
• Massive preparation and
• Several years to analyze the results after census is taken
• This is the main problem of census as a data source i.e. that the results are not available quickly

1. The first prof is generally very stressful for new MBBS entrants. The three main subjects are demanding enough.
a. Hence expecting them to study Community Medicine also is too much in general. Some strong personalities can do it; they are encouraged to start from 1st prof itself.
b. Others are advised to at least attend the lectures and try to grasp what is being taught.
2. Start studying from 2nd prof itself. Find half to one hour a day from your studies for the subject

Community Participation
Community participation is the process by which individuals and families assume responsibility for their own health and of the community they live in.
Community participation ensures the following:
1. Self-reliance and sustainability:
a. Individuals come to know of the health problems of the community and learn the ways and means of overcoming these. They no longer are mere passive beneficiaries of Government aid.
b. They can demand supplies from the administration for health work.

Inter-Sectoral Coordination
Medical care forms only one part of health care. It comes into play when health deteriorates and disease develops.
Primary health care is concerned with health promotion, disease prevention and then management of disease if it occurs.
For achieving this, input from sectors other than health is of paramount importance.
Primary health care requires support of other sectors.

The principles of Primary Care are listed below:
1. Equitable distribution
2. Community participation
3. Inter-sectoral coordination
4. Appropriate technology
