A census of agriculture is a statistical operation for collecting, processing, and disseminating data on the agricultural structure. It covers the whole or a significant part of the country. Typical structural data collected in a census of agriculture are farm size, land tenure, land use, crop area harvested, irrigation, livestock number, labor and other agricultural inputs (e.g. feed, fertilizers, labor, fuel). In an agricultural census, the data are usually collected directly from agricultural holdings but may also include some community level data.
