Tanzania is improving the accuracy and reliability of health coverage data by aligning national health system denominators with the 2022 Population and Housing Census. This ensures that reported coverage from facilities to national dashboards reflects the real population landscape.
From 8–10 September 2025 in Morogoro, stakeholders convened to compare 2012- and 2022-based population projections and assess their impact on key health indicators, moving toward decision-grade reporting across all levels.
Objective: Ensure accurate, timely, and reliable monitoring by integrating 2022 census-based projections into national health reporting.
Leadership and Collaboration:
The initiative was led by the Ministry of Health (DRMCH, DICT, M&E, and DPS–IVD) in collaboration with PORALG, NBS, NIMR, and the University of Dar es Salaam’s DHIS2 Lab, alongside partners including JSI and Afya Intelligence.
Key Insights Validated:
-
NBS presented updated 2022 population projections for alignment
-
Teams compared 2012 vs. 2022 denominators across:
-
RCH: ANC, early booking, institutional deliveries
-
HMIS: Outpatient Department (OPD) indicators
-
IVD: BCG, DTP1, DTP3, MR2, and HPV coverage
-
-
Identified discrepancies and developed council-level follow-up actions for improvement
Strategic Approach:
-
Evidence-led group analysis with clear methodology and defined limits
-
Focus on denominator accuracy to ensure meaningful coverage metrics
-
Targeted interventions to address identified data gaps at subnational levels
Alignment and Impact:
This exercise strengthens accurate monitoring and reporting within the national HMIS architecture and supports data-driven decision-making for improved health service delivery, accountability, and equitable resource allocation.
