The COVID-19 pandemic and other recent public health responses have highlighted significant challenges in global mortality data collection, with approximately 40% of deaths unregistered and fragmented reporting systems hampering public health responses. This paper supports the establishment of routine mortality surveillance as a core function of essential public health services, emphasising the need for integration with civil registration and vital statistics (CRVS) systems. By leveraging existing frameworks and proposing a Theory of Change (ToC), we outline critical linkages between CRVS and mortality surveillance that enhance data accuracy, timeliness and utility for public health decision-making. The paper provides examples across key enablers—policies, agreements and legislation; infrastructure; governance, funding and resources; and people and organisational culture—that facilitate these linkages. We also present examples from initiatives like the Africa CDC’s Mortality Surveillance Programme to illustrate effective strategies in low- and middle-income countries (LMICs). The ToC serves as a blueprint for stakeholders to implement strategic interventions aimed at overcoming barriers to linking systems and data integration and utilisation. Ultimately, this paper underscores the importance of coordinated efforts among national public health agencies, civil registration authorities and other stakeholders to improve mortality data systems globally. By addressing these systemic challenges through enhanced collaboration and technological innovation, we can significantly advance public health outcomes and policy formulation in response to future health crises.
