The Central Statistics Office produces two preliminary estimates and a final estimate for each year's agricultural output, input and income. The first preliminary estimate is published in early December. The second estimate is published in late January — early February. This second estimate is obviously based on more complete information than the first estimate. For instance, the preliminary indications from the December Livestock Enumertion are taken into account in the January-February estimate. The final estimate in July is made on the basis of the final figures for the previous year.
