Alternative sampling frames and administrative data; which is the best data source for agricultural statistics?

The extraordinary increase of ability to handle and manipulate large sets of data suggests an extensive use of administrative data for saving money, reducing response burden, producing figures for very detailed domains and estimating transition over time.

Some of these disadvantages can be removed if registers are combined with list or area frame sample surveys through calibration estimators or multiple frames methodology
