2.1. Data description

The livestock and meat statistics are collected under Regulation (EC) No 1165/2008 since 2009. They cover slaughtering in slaughterhouses (monthly) and other slaughtering (annual), GIP (gross indigenous production) forecast (semi-annual or quarterly data), and livestock statistics (once or twice a year), including regional statistics (annual).This template lists the questions constituting the quality report required in Article 17 of EU Regulation N°1165/2008 on livestock and meat statistics. 

This quality report covers the year 2019 and all the quality indicators already reported for year 2010 on the statistical processes used to meet the Regulation (EC) No 1165/2008.

6. Accuracy and reliability Top

See the items 6.2., 6.3., 6.5. and 6.6.
6.1. Accuracy - overall

Two factors contribute to the accuracy and reliability of this survey. Firstly, the survey is a census of the large pig farms (greater than 200 head) which are responsible for the vast majority of pig farming within the state. Secondly the survey has a response rate of over 98%.

Threshold or other conditions
Small farms/slaughterhouses
Farms/slaughterhouses which have just started/ceased
Empty farms/buildings 2
Farms without milk quotas
Emergency slaughtering
Non-agricultural units are excluded (e.g. slaughterhouses or animal traders)
A2: Rate of over coverage (%)
The rate of over coverage is the proportion of units accessible in the frame that do not belong to the target population (i.e. are ‘out of scope’).

0
Further comments

Specialised pig farms, totalling 287 specialised pig farms were included in the survey for June 2020, accounting for 87% of the estimated total pig population. There is no over coverage as all respondents are active specialist pig farms which all belong in the target population.

1 Some countries may cover or exclude some specific territories, either remote or kept out of some studies because of their status, for instance French overseas "departments", neighbour micro-states, Mount Athos, etc.
2 On the date of the survey, some farms or holding can be provisionally empty, for instance for sanitary emptying, whereas they have normally an activity and take part to the frame.

10. Cost and Burden Top

Efforts are made to reduce the cost and burden of data collection on respondents. We aim to minimise the cost and burden by using all available administrative data sources and keeping data requests to a minimum. Two surveys are issued per year. The cost of these surveys (approx 330 one page surveys twice a year) include the cost of printing materials, postage, return postage and labor of CSO employees who work on this survey. No superfluous data is requested from the pig farm enterprises.
