The historical use of Hanja in Korea has had a change over time. Some Hanja have started to be trended between different ideas. In Writing and Literacy in Chinese, Korean, and Japanese by Insup Taylor and M. Martin Taylor, the authors explain that from the 1920s to 1990 the use of Hanja as a social idea and political idea has decreased drastically. In 1920, in leading newspapers Hanja was being used 100% in political headlines and 80% in social headlines. By 1990, headlines Hanja use was under 20% for both political and social aspects. In body text, political stories saw just over 60% use, and social saw 0% use. By 1990, the political aspect had dropped to about 1-5%. This shows that Hanja would not be able to gain the use of simplified characters due to the decrease of usage. Thus, to the knowledge that is still being used traditional characters would remain the traditional style of Hanja being used.
