China has long held the 1st place in the world population ranking. However, its estimated population of 1.42 billion is expected to be surpassed this year by India. A quick look at the population dimensions of the provinces is enough to understand the complexity.
Despite the reduced birth rate, population growth added more than 75 million inhabitants to the country's contingent - or almost a Germany, with 83 million, the most populous in Europe.
In fact, the 5 largest provinces in China exceed the population of Germany: Guangdong with over 126 million, Shandong with 102 million, Henan with 99 million, Jiangsu with 85 million and Sichuan with 84 million. The largest Chinese province, Guangdong, would rank 11th in the world, equivalent to Japan.
The map above illustrates "how many countries fit in China" and thus the scale of its challenges. Just think of the demands for employment, transportation, housing, etc. Or in demand for goods and services - such as garbage collection. It is no trivial task.
