The Methodologies We Use

Assessing the progress towards the SDGs with the latest standards


The Poverty Probability Index (PPI) - former the Progress out of Poverty Index - is a poverty measurement tool used by several organizations worldwide to evaluate social impact at the household level.
The PPI is based on ten questions, depending on the country of implementation, which aims at characterizing the probability that the households live below the poverty line.
Our data collection and monitoring tools include the PPI questions and scorecards for several countries, and are constantly updated with the latest releases.


The SDG targets on drinking water, sanitation and hygiene (WASH) aims to achieve, by 2030,
  • universal and equitable access to safe and affordable drinking water for all
  • universal access to adequate and equitable sanitation and hygiene for all
  • end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations
HEDERA implements the latest WASH assessment framework developed by the WHO/UNICEF Joint Monitoring Program for Water Supply, Sanitation and Hygiene (JMP).


Access to energy is multidimensional, and cannot be measured purely by binary indicators, such as the availability of a grid connection or the usage of biomass for cooking.
HEDERA enables the efficient implementation of the ESMAP Multi-Tier Framework, which describes the full dimensionality of energy access at the household level based on multiple attributes.
