Investigating the causal relationship between wealth index and ICT skills: a mediation analysis approach

This study examines the relationship between the wealth index (WI) and Information and Communication Technology (ICT) skills among women aged 15–49 in Bangladesh. The research aims to establish a cause-and-effect relationship between WI and ICT skills, while also examining how education mediates this relationship. Using the data from the Bangladesh Multiple Indicator Cluster Survey (MICS) Program 2019, a two-stage stratified clustered sampling method yielded a sample of 64,378 women. The analysis employed inverse probability weighting (IPW) to assess the causal effect of WI on ICT skills while investigating the mediating role of education in this cause-and-effect relationship through causal mediation analysis. The findings demonstrate a significant relationship between higher economic status and increased ICT proficiency among women aged 15–49 in Bangladesh. Mediation analysis reveals education status as a significant mediator, indicating that educational attainment plays a vital role in linking wealth and ICT skills among women. Sensitivity analysis indicates the observed effect estimates are robust to unmeasured confounding. This research underscores the importance of economic empowerment and educational interventions in narrowing the digital divide and fostering ICT skills development among women, particularly in rural and economically disadvantaged communities.
