Privacy International's 2007 survey, covering 47 countries, indicated that there had been an increase in surveillance and a decline in the performance of privacy safeguards, compared to the previous year. Balancing these factors, eight countries were rated as being 'endemic surveillance societies'. Of these eight, China, Malaysia and Russia scored lowest, followed jointly by Singapore and the United Kingdom, then jointly by Taiwan (Republic of China), Thailand and the United States. The best ranking was given to Greece, which was judged to have 'adequate safeguards against abuse'.
