Rice: the changing production leaders

How to read this diagram

Choose the latest year with at least half the maximum annual reporting coverage (68 minimum). Retain an eleven-year fixed cohort with non-missing, non-negative values in every year. Rank all 114 cohort economies each year by production in t; equal values sort by reporting code to give distinct ordinal ranks. Display the eight largest producers in the final year. Every cohort observation and calculated rank remains in the exports. These are cohort ranks, not an assertion of a complete world ranking. Line position shows rank, not output magnitude; connecting segments summarize annual observations.

Rice · production in retained t units. The source's product and statistical category remain distinct from other measures. Values preserve the retained normalized observation and flag; no unit conversion is applied.

All retained crop/livestock product, element and unit combinations. Production (t), harvested area (ha) and yield (kg/ha) remain distinct. Overlapping product groups must not be added together. Flags and normalized source observations are retained; unavailable source rows are not reconstructed. China means mainland China in this source normalization.

Values, source flags and notes retain the reviewed snapshot. No new observations are acquired or interpolated.
