Death is arguably the most important event in our lives, but ironically, it is very difficult to measure. In this paper we try to investigate if mobile phone surveys can help us overcome this challenge in 25 low and middle income countries. Tldr: there is a potential for selection bias, but it appears to be modest, and using sample post-stratification weights partially alleviate this bias, though not uniformly.
Using data from 25 Demographic and Health Surveys, this study advances our understanding of sample selection bias in mobile phone survey estimates of demographic indicators ➡️
