5.3.1. Data completeness - rate

Not applicable for Pesticide Use Statistics because in this data collection, there is no target on the number of data. Member States are asked to collect data on representative crops without stipulating the number of crops.

6. Accuracy and reliability Top

In a general statistical sense, the statistical data accuracy refers to how close the estimations are as against real values. The pesticide use in agriculture in 2018 was a sample survey. The related tools were: statistical questionnaire (PUA), interviewer’s methodological guide, pesticide nomenclature and agricultural holding nomenclature. At county level, the data entry errors were spotted and solved by the specialists of the County Statistical Offices. The most frequent data collection or entry errors were those related to the correlation of pesticide-treated areas with the pesticide amount used per area unit. Other types of data collection/entry errors were due to the unit of measure (kg or litres), trade product name and its code. At central level, the results were compared with data from other surveys (pesticide sales in 2018 and main crop areas in 2018). The list of active substances in pesticide composition is in line with Annex III to Regulation (EC) No 1185/2009.

The bias between the frame population and target population represents the coverage error. The non-response error appears as a result of missing values and accounts for 1.7% (939 holdings).

According to the completeness code, we have the following statistics:

- full interview for 46 236 holdings (83.5%);

- closed-down farms = 1290 (2.3%);

- temporarily inactive holdings = 6 934 (12.5%);

- refused interview for 98 holdings (0.2%);

- unidentified holdings = 55 (0.1%);

- unvisited holdings = 31 (0.1%);

- other cases = 755 (1.3%).
