World Health OrganizationConceptNote,19May2025 ReimaginingHealth Data Collection:The Role and Future ofPopulation-Based Health Surveys World Health Organization Concept Note,19May2025 Reliable, timely, and disaggregated health data are essential for national leadership and globalaccountability. Countries needversatile, modular, integrated and sustainable data generation systems todeliver on their health priorities. WHO is coordinating efforts to support countries, with partners, toachieve these goals. Executive Summary Reliable, timely, and disaggregated health data are essential for national leadership and globalaccountability. The global health data landscape is at a turning point.As donor support for critical survey platformslikethe Demographic and Health Surveys(DHS)Program faces potential closure,manycountries risk losingessential data for planning,prioritizing,deliveryand accountability.Countries cannot meet thesechallenges alone. Stronger coordination, investment, and technical support are critical. Meanwhile, advances in tools, technology, and partnerships create an opportunity for more efficient andsustainable systems.Countries need versatile, modular, integrated and sustainable data generation systemsto deliver on their health priorities.WHO is coordinating efforts to support countries, with partners, toachieve these goals. WHO isproposing toconvene countries and partnersto define priorities, align efforts, and chart asustainable, country-led model for the future of health datacollection. Objectives 1.Commitment to strengthen country-led, transparent, and actionable data systems•Transition fromexternally led surveys (e.g., DHS) to sustainablenational,multimodal, efficient systems•Adopt open data standards to enable collaboration, accountability and interoperability•Build capacityto generate, analyze, and act on data2.Explore cost-effective,modular,and sustainablesurveymodels3.Strengthen coordination, financing, and technical support mechanisms Key Themes •Urgentsupport for countries to maintain data continuity.•Aligning global survey platforms for greater efficiency and impact.•Financing models for short-and long-term sustainability.•Review emerging survey technologiesand innovations instandards,protocols, andsurvey designs.•Strengthening national leadership and institutional capacity. Expected Outcomes •Immediate action plans toaddressdata gaps.•Agreement on guiding principles for sustainable, integrated survey systems.•Commitments from donors and countries to pioneer innovative survey approaches. Background and Context Reliable health data are aninvaluableasset. Countries depend on timely, relevant, and accurate data todetect disease outbreaks, monitor health trends,improveservice coverage, track risk factors, guideevidence-based actions,informand evaluate public health policies. Strong health data systems are centralto national planning, global reporting, and resilient health systems. Monitoring health-related Sustainable Development Goals (SDGs) requires well-functioning national datasystems, including population-based surveys, civil registration and vital statistics (CRVS), facility andadministrative records, and disease surveillance. Many indicators also rely on data from outside the healthsector. Population-based surveys are especially important. Theyprovideprimary datafor 29 of33 health-relatedSDG indicators and contribute to 80 of the 231 global SDG indicators(Asma et al. 2020).Surveysprovide population-representative data on health behaviors, risk factors, service coverage,financialprotection, and social determinants of health.In many low-and middle-income countries (LMICs), theyare often the only way to collect disaggregated data by sex, age, income, education, minority status, andgeolocation–essential for identifying vulnerable and marginalized populations. Yet gaps remain. A third of countries lack recentprimarydata for half of the health-related SDGindicators(SCORE Global Report 2020).Surveys are often delayed, limited in scope, and disconnectedfrom nationalhealth plan anddata systems. Key topics–mental health, disability, adult mortality, andfinancial hardship from healthcareareunderrepresented. Sustainability isfragile. Only 3% of household surveys in low-income and 8% inlower-middle-incomecountriesare fully governments-financed. Most rely on donorfundinglimitingcontinuity andnationalownershipand investments areuneven across topics. Thepossibleend ofDemographic and Health Surveys(DHS) Program marks a major shift.DHS has beena cornerstone for 40 years, supporting over 90 countries. Without it, many countries risk losing criticalhealth and demographic data. WHO studies show DHS contributes the largest share of outcome indicatorsfor WHO’s GPW Results FrameworkFor over 40 years, DHS has supported more than 90low-resourcedcountriesin trackingkey health indicators, includingmaternal and child health, reproductive health,nutritionandservice coverage.
