Members of the Akha ethnic minority group, who are living in Thailand, joined other stateless groups as they gather outside the Government House in Bangkok March 29, 2012. Activists have reported more than 400,000 stateless people are living in Thailand, and have urged the government to certify them with Thai nationality, as well as calling for a better standard of living.
