China and India, which are currently the first and second largest countries, have grown to become world economic powers. In my opinion, population is an economic power because business opportunities certainly require a long process from production to consumption, countries that have large populations are certainly a very useful resource and important for the economy.
With the large population of these two countries, the economic chain will continue to run because everyone definitely needs the food they buy every day, so that food and clothing makers will continue to run more stably. Because each of them also has to work in order to earn money for their own needs, so the large number of people living in these two countries will certainly make the country's economic turnover continue to increase quite well. And it will also be easier for anyone to take advantage of jobs that can make more money.
