Which country has the largest population among those listed?

The selection of China as the country with the largest population is based on the most recent demographic data available. As of the latest estimates, China has a population that exceeds 1.4 billion people, making it the most populous country in the world. Despite changes in growth rates and predictions about future demographic shifts, China has maintained this status for several decades.

In the context of the other countries listed, India is often cited as having a population that is close to China's and may surpass it in the near future, but as of the latest figures, it has not yet done so. Nigeria, while experiencing rapid population growth, has a population that is significantly less than that of China. Brazil has the largest population in South America, but it is also much smaller compared to China's population.

This distinction is crucial in understanding global demographics, as population size has significant implications for economic development, resource allocation, and political power on the world stage.
