Notes: [] RII's in parentheses indicate that results may be an artefact due to combination of population heaping and a non-linear association of under-5 mortality with wealth; a rates are not shown due to small sample size (smaller then 500), referring to the denominator, i.e. live births during the last 10 years preceding the survey; b empty cell due to heaping (see Table 2); + 10–30% change in RII compared to the WB index; ++ >30% change in RII compared to WB index
