Countries with comparatively high gaps may have inadequate coverage of social protection. However, it useful to test and discuss results based on different poverty lines, to explore how the country ranking varies and if poverty levels change dramatically with small changes in the poverty line value (for example a substantial increase in poverty levels due to a small increase in the value of the poverty line, means that there is a quite high density of households just above the original poverty line). In general, however, sizeable re-ranking is quite limited.
