 the senses. Senses is a very important factor because to count the population and to count the population for the purpose to specifically regarding the geographical understanding, regarding the understanding that how and why the state can settle down the people and what type of facilities the government has to provide to the people in specific areas. Senses is an important factor for any country. The concept of Mardam Shomari is that until the data is collected, no country will be able to find out who and how many people are in the area. Until that number is not found with its total details, no country can properly develop it. Neither can the people be taken into account according to their percentage. Specially those countries that are currently going through that space where there is a quota system in the political context, some particular area, some particular area or some particular community, there is more sense of importance there. Because our senses provides more reliable and accurate data if properly numbered, it is one of the many sources for collecting demographic data and conducting of senses has a long history. But modern senses were first held in the 17th century. Even at the beginning, if we look at it in a very historical context, Aristotle, Plato, Aristotle, the concept of city-states has fixed the number. How much number of population will be beneficial or useful for a city-state. But then after that, the population increased and in the 17th century, we see that the concept of senses was that until we count people, until we complete the count of the population, how can we divide them, how can we plan for them. So this concept, if we look at human development, is an extremely important step. Because some countries like Ethiopia, they have held their first senses in the recent years. Now, on the one hand, the concept of the 17th century, we see that some people are far away from it and it can also be an example of Ethiopia. But the important thing for us is that if there were no senses in Ethiopia, then we are also seeing the effects of it. We can also observe the implications that those countries that do not believe in senses, there are many problems in the distribution of resources. There are two techniques of conducting senses, the gyro and effecto. The gyro is the technique of counting of people according to the permanent place of location or residence. This is a very popular pattern where the location of the people is counted according to the location of the people. The main advantages of this are that it gives a permanent picture of a community and it provides more realistic and useful statistics. But there are some disadvantages too and the disadvantages are that some persons may be omitted from the count. A household member who is temporarily away from home may be missed from being counted unless. And so we can say that another important thing is that some people may be counted twice. Another method, another technique is the defecto one and defecto is the technique of conducting senses refers to counting persons where they are present at the time of the senses period. Now wherever a person is present, if he is counted in the same place, this is a defecto method. There are some benefits of this as well. One thing is that there is less chance for the omission of persons from the count. Now wherever a person is counted, there will be less chance for the omission of persons from the count. But the disadvantage of this is that it is too much. Because the information gathering will be being cut about the people. If a person who is in a place, if he moves somewhere in another country, the information will not come about the same person again. Then there are many people, those are travelling and those have left their permanent residences and they can be settled at some places. And if they are not at their destination, then at the day of the senses, then how will they be counted? So this is incomplete information about the population. But we can say that in the modern time periods, when there are lot of modern technologies and modern data regarding e-data specifically, so in the presence of e-data, I think the senses can be linked with the information provided by the people for their legal, like the ID card base, the information about the ID cards, their families are also available. So if the senses are linked with traditional methods and modern technology, then in our countries too, there are many such issues that are created based on the senses. They can also be settled down. Yes, the source where e-data, digital data is located is behind it. Over there, obviously, the de facto or de jure or whatever method is more applicable, where people are more satisfied with this method, through the senses, people can get information so that future policy, economic, social planning, those governments can properly manage it.
