2.1. Data description

Annual crop statistics provide statistics on the area under main arable crops, vegetables and permanent crops and production and yield levels.  The statistics are collected from  a wide variety of sources: surveys, administrative sources, experts and other data providers. The data collection covers early estimates (before the harvest) and the final data. Data are collected mostly at national level but for some crops also regional data exist (NUTS1/2).

2.2. Classification system

Hierarchical crop classification system

2.3. Coverage - sector

Growing of non-perennial crops, perennial crops and plant propagation (NACE A01.1-01.3)

2.4. Statistical concepts and definitions

See: Annual crop statistics Handbook

2.5. Statistical unit

Utilised agricultural area cultivated by an agricultural holding.

2.6. Statistical population

All agricultural holdings growing crops.

2.7. Reference area

Use purpose of the estimates?

To provide update crops statistics for territorial bodies, policy decisions, category associations

What kind of expertise the experts have?

Statistical and agronomic skills

What kind of estimation methods were used?

Panel survey addressed to main crops producers and analysts, in order to estimate used surfaces and to update the average production by hectar.

Statistics are produced using expert information. Data are provided by local authorities that collect experts evaluations on area and yield of different crops. The auxiliary information could be included in expert's estimate, such as verifying the availability of external sources (eg professional bodies or associations of producers, administrative sources, auxiliary sources of data related to the cultivation being estimated). Crops under investigation are different for each month and take into account the phenological stage of cultivation. For this reason more than one estimate can be determined for each crop during the year (provisional, temporary or permanent).

Were there any differences in the definition of the variables between the experts' estimates and those described in the Regulation? NO
If yes, please describe the differences
What measures were taken to eliminate the differences?
How were the reliability, accuracy and coherence (comparison to other available data) of the data originated from experts' estimates (ante- and/or ex-post)checked?
