Data: gold/all_world_wheat_known_flows.parquet
Average quarterly share (%) each regional origin represents of its own wheat class total to Mexico over the last 7 complete crop years (≥2018). Quarters start in June.
Regional avg % of class × class minimum % of Mexico imports. Estimates each origin's minimum share of total Mexico wheat imports.
All regional origins for each wheat class combined (e.g. all HRW origins summed together).
Quarters: Q1 = Jun/Jul/Aug, Q2 = Sep/Oct/Nov, Q3 = Dec/Jan/Feb, Q4 = Mar/Apr/May
Share = exporter volume / total Mexico imports for that quarter+crop_year. Min is the lowest observed share across all complete crop years.
Fitted log-normal distribution of quarterly share observations. X = share %, Y = probability density.
