Overview

This report presents comparative results from the Iron Fortified Rice (FFR) survey across survey rounds. The tables summarize survey coverage, FFR utilization and rice-processing practices, mean haemoglobin and inflammation-adjusted ferritin concentrations, survey-adjusted anaemia prevalence, iron deficiency, iron deficiency anaemia, and iron overload.

Comparison of State-wise Survey Coverage across the survey rounds

The table presents the number of primary sampling units (PSUs), households, and participants with available blood samples by Region, State, District, and survey year. PSU identification uses the combination of State and PSU number.
