the form of dry grain; sweet potatoes, potatoes, cassava are recorded in form of fresh
                       bulbs; tea in form of  fresh buds, coffee in form of dry kernel, rubber in form of
                       dried latex, fruits in form of  fresh fruits, etc.
                           Yield of agricultural crops refers to the main product per one area unit of a
                       certain  agricultural  crop  or  group  of  agricultural  crops  actually  harvested  in  a
                       production season or in a year on average planted area.
                            For annual crops:
                                                               Harvested production
                                     Planted yield    =
                                                                   Planted area

                                                              Harvested production
                                      Harvested yield  =
                                                                 Harvested area
                            For perennial crops:
                                                           Harvested production (year)
                                     Harvested yield
                                      (season, year)   =     Productive area (year)

                           Harvested area: An indicator refers to the total cultivated/planted area of a certain
                       crop or group of crops in a year, from which the crop production is reached at least
                       30%  of  yield  of  the  ordinary  year.  For  annual  crops,  harvested  area  is  equal  the
                       cultivated area minus complete loss area; for perennial crops, it is equal productive
                       area minus complete loss area.
                           Production  of  cereals  include  output  of  paddy,  maize,  and  others  grain  crops
                       such as wheat, millet, kaoliang, etc. produced in a given period of time. This indicator
                       does not include production of starchy root crops.
                           Production of paddy (also known as production of paddy in basket) is the clean
                       and dried paddy output of all crops in the year. The paddy output of a year is valid for
                       that year, excluding loss during harvest, transport, and threshing, etc. (destroyed by
                       mice, loss in fields, damage before storage).
                           Production of maize is the output of clean and dried maize harvested during the
                       year.
                           Production of starchy root crops refers to the output of cassava, sweet potatoes,
                       winged  yam,  taro,  edible  canna,  and  other  starchy  root  crops  produced  in  a  given
                       period.
                           The number of livestock, poultry and other domestic animals is the number of
                       heads of livestock, poultry or others  alive  in the process of livestock production at the
