Javanese is the tenth largest language by native speakers and the largest language without official status at the national level. It is spoken or understood by approximately 100 million people. At least 45% of the total population of Indonesia are of Javanese descent or live in an area where Javanese is the dominant language. All seven Indonesian presidents since 1945 have been of Javanese descent. It is therefore not surprising that Javanese has had a deep influence on the development of Indonesian, the national language of Indonesia.
