In annual polls conducted by National Chengchi University, Taiwanese identification has increased substantially since the early 1990s, while Chinese identification has fallen to a low level, and identification as both has also seen a reduction. In 1992, 17.6 percent of respondents identified as Taiwanese, 25.5 percent as Chinese, 46.4 percent as both, and 10.5 percent non-response. In June 2021, 63.3 percent identified as Taiwanese, 2.6 percent as Chinese, 31.4 percent as both, and 2.7 percent non-response. A survey conducted in Taiwan by Global Views Survey Research Center in July 2009 showed that 82.8 percent of respondents consider the ROC and the PRC as two separate countries with each developing on its own but 80.2 percent think they are members of the Chinese.
