A household counts as deprived if it uses any one listed fuel.

Evidence

The MPI illustrates nicely how the logical OR makes a lot of sense at the data level. In the data aggregation column of table 2.1, a number of the indicators use the logical OR. Each of these indicators is dichotomous, but as we will see in chapters down the road, the logic works just as nicely for continuous variables. For example, the cooking fuel indicator consists of cooking with dung OR wood OR charcoal, each coded dichotomously. If the household uses any one or any combination of these three it is considered deprived. — Gary Goertz, Social Science Concepts and Measurement, 257

Categorization

• DEFINE: Explains how the logical OR operates when aggregating dichotomous deprivation indicators into a single measure.
• XREF: Connects to the OR/AND aggregation logic of concept-structure work (Goertz’s own two-level concept framework, Sartori on concept stretching).
• ADDENDUM: Could feed a piece on measurement design: the ‘Completeness Guideline’ for OR lists parallels the question of when an indicator list is truly exhaustive.
