    By March 2021, COVID-19 had been spreading globally for over a year, and all countries had implemented various infection prevention measures. In Japan, COVID-19 was on its third wave. We conducted a large-scale survey targeting people in 42 cities in 29 countries to clarify the international trends in people’s media usage; evaluation of governments’ infection prevention policies; everyday infection prevention behavior; changes in values, work, and lifestyles; and attitudes towards privacy. Such large-scale worldwide surveys are rare.
    This survey was conducted as joint research between Tokyo Woman’s Christian University and NTT Secure Platform Laboratories (now NTT Social Informatics Laboratories). Research Groups of Prof. Hashimoto designed the question items of information-collection behavior, evaluation of governments’ infection prevention policies, and so on, and NTT Secure Platform Laboratories designed those of privacy attitudes.

    Today, we are publishing the outline of the survey and the simple tabulation data for others to utilize the survey results. We also summarize privacy related results. You can download them from the following links.
