This rate presents the acreage of wheat, as recorded by the Agricultural Census or similar surveys. The divisor used to compute a percentage is the total area of the reporting unit, rather than the total acreage of all crops, and this total area has had sometimes to be obtained from other sources such as the Population Census.
