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.

Over 40 million people lack access to an improved water source and more than 110 million of the country’s 240 million population has no access to improved sanitation. Only about 2% of people have access to sewerage in urban areas; this is one of the lowest in the world among middle-income countries. Water pollution is widespread on Bali and Java.
