Slot: Reason Population Weighting Is Missing (population_weighting_source_missing_reason)
Reason population_weighting_source is null.
Tier: optional
Why this slot matters
A blank weighting source is ambiguous between "no weighting was applied" and "the source was not recorded". Recording the reason keeps unweighted products from looking like incompletely documented weighted ones and lets automated checks pass legitimately null records.
In plain terms
When the population-weighting field above is empty, this field explains why — usually because the dataset is a plain average with no population weighting at all. It makes the emptiness intentional rather than an oversight.
