IUS 2020 reached a sample of 2,401 Internet users and 384 non-Internet users at the national level and a total of 384 Internet users for each state to meet the requirement for state-level surveys, Table 1 shown a percentage of Malaysian internet users for the years 2018 and 2020. Respondents were selected randomly, and the interviews were carried out through telephone interview. IUS 2020 also focuses on emerging Internet issues introduced in the previous surveys; namely online content, online child safety and online privacy/security. Table 1.
