Techniques of census

Census Techniques

1. De facto method:

The census that is conducted on the basis of the actual place of residence is known as a de facto method. People are counted in a place where they are residing. Under this method, the government declares a fixed day as 'census day' and all the people are pre-informed of counting.

2. De jure method:

The census that is conducted on the basis of a permanent place of residence is known as a de jure method. People are counted in a place where they permanently reside. Under this method, the government fixes two to three days for counting the population.

3. Modified De jure method:

The census that is conducted on the basis of the usual place of residence is known as the modified De jure method. This method was developed to overcome the drawbacks of the other two methods, and it is the most scientific method of population counting. Under this method, the usual place of residence of six months and over is considered while counting people.
