The United Nations defines the population census as:

‘‘Total process of Collecting, Evaluating, Analyzing, and publishing or otherwise disseminating demographic, economic and social data pertaining, at a specified time, to all persons in a country or in a well delimited part of a country’’. (UN,1998)

Types of population census:
There are two approaches of population census are;

De jure Approach: This is done by counting and obtaining information from individuals at their places of residence during census.
De facto approach: It means whenever the individual happens to be at the census period, is where he will be counted and information obtained regardless of his place of residence or abode.

Theory of Attributes- Basic concept and their applications: ATTRIBUTES:       Literally, an attribute means a quality or characteristic.Theory of attributes deals with qualitative characteristics  which not amenable to  quantitative measurements  are and hence need slightly different statistical treatment from that of the  variables. Examples of attributes are drinking,smoking, blindness, health, honesty, etc. An attribute may be marked by its presence (possession) or absence (dispossession) in  member of given population. It may be pointed out that the methods of statistical analysis applicable to the study of variables can also be used to a great extent in the theory of attributes and vice-versa. For example, the presence or absence of an attribute  may be regarded as changes in the values of a variable which can possess only two values, viz., 0 and 1.

A.R Statistics

                                    Historical Note of Statistics       ‘Statistics’ is derived from the Latin word ‘status’ which means a political state. This suggests that statistics is as old as human civilisation. In the year 3050 B.C., perhaps the first census was held in Egypt. In India also, about 2000 years ago, we had an efficient system of collecting administrative statistics, particularly, during the regime of Chandra Gupta Maurya (324-300 B.C.). The system of collecting data related to births and deaths is mentioned in Kautilya’s Arthshastra (around 300 B.C.) A detailed account of administrative surveys conducted during Akbar’s regime is given in Ain-I-Akbari written by Abul Fazl. 2019-20        Captain John Graunt of London (1620-1674) is known as father of vital statistics due to his studies on statistics of births and deaths. Jacob Bernoulli (1654-1705) stated the Law of Large numbers in his book “Ars Conjectandi’, published in 1713.
