I intend to perform quantitative research entitled "The impact of Information and Communications Technology (ICT) on the psychosocial landscape of middle-income households, who were under COVID-19 lockdown" in Jaffna Divisional Secretariat division, Sri Lanka"

For the above research, I interviewed 40 participants. But the problem is, it is impossible to get the actual figure of those, who possess ICT facilities.

Please let me know how to determine quantitative sample size that represent an unknown number of population (because nobody knows how many people possess computers, phones and other ICT technologies in Jaffna Divisional Secretariat level)
