How these numbers are made. Yields and planted acres are USDA NASS Quick Stats state estimates, pulled with the reference period pinned to the full year, so in-season monthly forecasts never enter the table. Highest and lowest are over the published years shown, not all-time records. Averages are plain means of the published years in the stated window, printed with how many years they rest on (withheld below 3 of 5 or 6 of 10). The trend is an ordinary least-squares line through every published year (at least 8); it describes the past window and is not a forecast. County figures are NASS county corn yields, all practices, as carried by the AGSIST Farmland Atlas. Wheat here is winter wheat only (NASS “WHEAT, WINTER”); spring wheat and durum are not included. AGSIST’s NASS pull carries no state winter wheat planted-acres series, so no wheat acres column is shown.
