Survey method: Major crops are surveyed using direct observation of agricultural fields and facilities. All other crops are surveyed by interviewing farmers about recent planting/harvesting activity.
Sampling locations: Approximately 10,000 sampling locations are used, visited four times a year, to estimate agricultural data.
Crop calendar: Bangladesh has a well-defined crop calendar, and surveyors use this to accurately capture each crop's production and area planted.
Yield calculation: When ‘Yields’ are provided by the Agricultural Yearbook sources, they are calculated by precisely measuring a small subset of the sampling locations. When Yields have not been provided, they are calculated based on reported area and production.
Crop variants: In some cases, different crop variants were tracked in source documents, but only Total Crop figures are reported by FEWS NET. Source documents report Local, Pajam, Broadcast, HYV for Aman Rice; Broadcast, Local Transplanted, and HYV for Aus Rice; Local, HYV, and Hybrid for Boro Rice; Local, HYV, and Indian for Potato.

Steps have been taken to identify and correct flagrant errors in the data, such as misalignments, typos, and misreported figures.
