During the past few decades, substantial strides have been undertaken globally to mitigate child mortality rates. This study discerns the assessment of child mortality within the Commonwealth of Independent States (CIS) through the utilization of data sourced from the World Bank and UNICEF. For the remaining set of eight nations, the substantiating evidence is of a conjectural nature, derived from disparities observed within official datasets, alongside considerations regarding the delineation of live births. Methodologically, the analytical approach encompasses the utilization of linear regression models, specifically Ordinary Least Squares (OLS) and Generalized Least Squares (GLS) for binary outcomes, supplemented by the application of Fixed Effect models in a majority of instances. The findings demonstrated that the reduction of child mortality rates is notably linked to the availability of safe potable water and reliable electricity, as opposed to factors such as income or healthcare expenditures.
