Ethnic groups in Indonesia a significant number, particularly in Papua, speak Papuan languages. Chinese Indonesians population makes up a little less than 1% of the total Indonesian population according to the 2000 census. Some of these Indonesians of Chinese descent speak various Chinese dialects, most notably Hokkien and Hakka. The classification of ethnic groups in Indonesia is not rigid and in some cases unclear due to migrations, cultural and linguistic influences; for example some may consider Bantenese and Cirebonese to be members of the Javanese people; however, some others argue that they are different ethnic groups altogether since they have their own distinct dialects.

In just one hundred years, the population of Brazil decupled (x10), from about 17 million in 1900, or about 1% of the world population in that year, to about 176 million in 2000, or almost 3% of the global population in the very early 21st century. Mexico's population grew from 13.6 million in 1900 to about 112 million in 2010.
