India Overtakes China in Population: China is no longer the most populous country in the world. India has overtaken it and come at number one. In the beginning of this year itself, global experts had predicted that India’s population would be the highest in 2023 and now the new data released by the United Nations Population Fund (UNFPA) has confirmed it. According to United Nations (UNFPA) data, India now has two million more people than China. In such a situation, the question is that without conducting a census, how does it come to know that what is the population of a country?
How do you know?
How much has the population of the country increased or will it increase? If we answer this question directly, then it would be that it is all a game of statistics. The United Nations Population Fund (UNFPA), an organization associated with the United Nations, collects data related to the country and estimates the population of the country on the basis of that. By the way, mainly three things are kept in mind to find out the population. The first is the birth rate, the second is the death rate and the third is migration, that is, the number of people leaving the country and going to another country or coming. The population of any country is estimated from these three things.
Demography is counted by science
The techniques of estimating population without counting are called demography. UNFPA has also released its report on the basis of demographic data. In this, essential things from different fields like physical science, economic science, social science and computer science are used.
Estimation is based on many parameters
With the help of this technique, it can be estimated that what is the population of a country. In estimating the population of a country without counting, parameters such as birth and death rates, number of educated and illiterate people, sex ratio and age details of that country can be estimated. There may be population.
Government statistics are also used
UNFPA also uses data from government and various other organizations to estimate the population. Along with this, cooperation is also taken from telecom companies. Because, their towers are installed all over the country. In this way, the population of a country is estimated by collecting various types of information.
