Data collection and analysis tools

Monitoring the health situation, trends, progress and performance of health systems requires data from multiple sources on a wide variety of health topics. A core component of WHO’s support to Member States is to strengthen their capacity to collect, compile, manage, analyze and use health data mainly derived from population-based sources (household surveys, civil registration systems of vital events) and institution-based sources (administrative and operational activities of institutions, such as health facilities).

A technical package of five essential interventions with key elements to strengthen country health data and information systems and enable governments to track progress towards the health-related SDGs and national and subnational priorities.


Health Service Data



Regular, reliable data from health facilities and the resource systems that support them are central to ensuring availability and quality of health services.


World Health Survey Plus (WHS+)



The World Health Survey Plus (WHS+) is a multi-topic, multi-mode, and multi-platform survey system to address essential data gaps with the flexibility to adapt to countries’ unique data needs and to strengthen surveillance capacity. The WHS+ provides critical data for informed decision making.


WHO Mortality Database



An annual compilation of mortality data by age, sex and cause of death by country reported by Member States from Civil Registration and Vital Statistics (CRVS) Systems with historical data going back to 1950.


Civil registration and vital statistics (CRVS)



A well-functioning CRVS records all births and deaths, issues the relevant certificates, and compiles and shares vital statistics including cause of death information.


COVID-19 Question Bank



The Covid-19 Question Bank contains questions from surveys and data collection instruments used around the world.  You can explore these questions by selecting topic areas and optionally a specific survey. 



Harmonized Health Facility Assessment



Availability and quality of health services are integral to universal health coverage (UHC) and contribute achieving the sustainable development goals (SDGs). The harmonized health facility assessment (HHFA) modules represent a comprehensive external review tool that assesses whether health facilities have the appropriate systems in place to deliver services at required standards of quality.



DHIS2-based entomology and vector control data collection and collation tools


The DHIS2 standard modules for entomology and vector control have been developed to support countries to improve the collection and use of entomological and vector control interventions data and its use to inform programmatic decisions.

They are the results of the collaboration between WHO, its collaborating partners and Members States.
