NOTES ON METHODOLOGY
Source and methods
of data collection
Data on cereal, oilseed and
sugar beet production are the result of the following statistical surveys in the
field of crop production: the Survey on Actual Yields of Early Crops and Fruits
(PO-32 form) and the Survey on Actual Yields of Late Crops, Fruits and Grapes
(PO-33 form).
For calculations of import and export, the data from the export and import by
product codes of the Customs Tariff and Countries of Origin and the export and
import by product codes of the Combined Nomenclature and countries of origin
have been used.
Foreign trade was calculated separately for EU countries and non-EU countries.
Since 2013, Croatia’s import and export calculations have been made at the EU-28
level.
Expert estimates were made for stocks and losses by the Faculty of Agriculture
in Zagreb. Losses in cereals balance sheet were estimated in the range from 2%
to 5% in overall production.
The data on industrial use of wine have been taken over from the Annual Survey
on Consumed Raw Materials, Consumables and Energy Sources, IND-21/REPRO/G.
Human consumption per capita is calculated by dividing the quantity of goods
produced for human consumption by total population.
Definitions
Usable production
is the process of producing cereals and oilseeds in form of seed, while the
production of sugar from sugar beets is defined by degree of digestion, which
varies from 13% to 17%.
Initial stocks
are unused quantities of products on the first day of reference year, 1 July and
by definition are the same as the final stocks of the previous year.
Final stocks
are quantities in storage on the last day of reference year, 30 June.
Total imports
means imports of
products from non-EU countries produced in those countries as well as imports
from other EU Member States.
Total exports
means exports of products to non-EU countries and to other EU Member States.
Total domestic use
is composed of human consumption, industrial uses, seeds, processing, animal
feed and losses.
Human consumption
includes quantities of unprocessed and
processed products used for human consumption.
Industrial uses
includes quantities of products used for the production of alcoholic drinks and
other non-food products.
Seeds
includes quantities
of used seeds in crop production.
Animal feed
includes quantities of products used for
direct animal feed on the farm and industrial production of animal fodder.
Losses
include losses created during a production phase and in the marketing sector
(during storage, transport, conversion and packing).
Self-sufficiency rate
represents the ratio of usable production to total domestic use expressed in
percentages. It indicates the extent to which production in one country covers
domestic uses.
