The most vital source for obtaining vital statistics data is the registration technique that consists of the incessant and permanent registration of vital events, pertaining to births, deaths, migrations, marriages, etc. These data, in addition to their statistical utility, have their value as legal documents. The record of births performed on this world provides full details on the birthplace, sex, age and religion of the parents, legitimacy, number of previous descendants and their respective sexes, occupation of the father and place of birth of the parents. Similarly, the death record provides all the information on the place of death, age, sex, marital status, place of birth, occupation, number of descendants and cause of death. A similar type of information is also obtained with respect to marriages and migrants.

Many countries require mandatory registration of births and deaths under their laws. For example, every new birth that occurs must be reported to the authorities along with detailed information. Similarly, the death, marriage and migration of an individual or group of people are also recorded for future needs of any statistical study or government needs.

Registration method shortcomings:

In most of the nations, it is observed that there is no legislation in rural areas, which makes the registration of vital events such as birth, death, marriage and migration. When we calculate the national mortality or fatality rate, such regions are openly neglected and the result is definitely not correct. In such cases, the statisticians take calculation errors but still the result is not 100% accurate because the minimum 10 to 20% of the population is neglected due to lack of registration process. This is one of the main drawbacks of this registration process.

It also seems in many cases that the individual who is responsible for maintaining the records of such vital statistics is not very strict in fulfilling the responsibility, resulting in improper record keeping of these vital events.
