The aeticle should have said, but it's OPHI's Multidimensional Poverty Index. It checks the following:

• Nutrition
• Child mortality
• Years of schooling
• School attendance
• Cooking fuel
• Sanitation
• Drinking water
• Electricity
• Housing
• Assets

These are grouped into three categories (health, education, and standard of living) and each category is a third of the total score. Each indicator is an equal portion of the score for its category. If a household lacks access to at least a one third of the total after that weighting, it is deemed to be in poverty

So, as an example, if Household A has the health aspects covered (nutrition and child mortality), has access to education but their children don't actually attend, and does okay on the standard of living indicators (the last six) except for a lack of electricity, they would not count as being in poverty. If, however, their neighbours in Household B also lacked reliable access to cooking fuel and sanitation, Household B would count.
