Agricultural Census, 2010 - Poland

Abstract
---------------------------

The agricultural census and the survey on agricultural production methods were conducted jointly, i.e. within the same organisational structure, at the same time, and using a single electronic questionnaire and the same methods of data collection and processing. The agricultural census covered about 1.8 million of agricultural holdings. At all farms participating in the census, respondents were asked about the "other gainful activities carried out by the labour force" (OGA). The frame for the full survey was prepared on the basis of the list of holdings prepared for the census. When creating the list, an object-oriented approach was adopted for the first time, which meant that at the first stage the holdings (objects) were identified, their coordinates defined (they were located spatially) and their holders were identified on the basis of data from administrative sources. For domestic purposes, the farms with the smallest area, as well as those of little economic importance (meeting very low national thresholds) were included in the sample survey carried out jointly with the census. The survey on agricultural production methods was conducted on a sample of approximately 200 thousand farms in respect of the precision requirements set out in Regulation (EC) 1166/2008. The frame prepared for the agricultural census was used as the sampling frame.

The statistical unit was the agricultural holding, defined as "an agricultural area, including forest land, buildings or their parts, equipment and stock if they constitute or may constitute an organized economic unit as well as rights related to running the farm". Two types of holding were distinguished (i) the natural persons' holdings (to which thresholds were applied) and (ii) legal persons holdings (no threshold applied).

Census/enumeration data [cen]

Sampling procedure
---------------------------

(a) Frame
The frame for the agricultural census and the survey on agricultural production methods was based on the list of agricultural holdings. In the process of the list of farms creation for the needs of AC and SAPM 2010 the objective approach was used for the first time, which meant that on the first stage of work agricultural holdings were identified, its coordinates were defined (farms were located in space), and its holder was determined according to administrative data as described below. The list creation started from identification of all land parcels used for agricultural purposes. The land parcels found in the set of the Agency for Restructuring and Modernisation of Agriculture (including the Records of holdings and Records of producers) were combined into holding and had their holders defined. For the rest of land parcels,
the holders were defined from the Records of Land and Buildings, afterwards the data concerning users were updated by the set of Real Property Tax Record.

Mode of data collection
---------------------------

Computer Assisted Personal Interview [capi]

Research instrument
---------------------------

A single electronic questionnaire was used for data collection, combining information related to both the AC 2010 and the SAPM. The census covered all 16 core items recommended in the WCA 2010.

Questionnaire:

Section 0. Identifying characters
Section 1. Land use
Section 2. Economic activity
Section 3. Income structure
Section 4. Sown and other area
Section 5. Livestock
Section 6. tractor, machines and equipment
Section 7. Use of fertilizers
Section 8. Labour force
Section 9. Agricultural production methods

a. DATA PROCESSING AND ARCHIVING
The data captured through the CAPI, CATI and CAWI channels were gathered in the Operational Microdata Base (OMB) built for the AC 2010 and processed there (including control and correction of data, as well as completing the file obtained in the AC with the data obtained from administrative sources, imputed units and estimation for the SAPM). The data, depersonalized and validated in the OMB, were exported to an Analytical Microdata Base (AMB) to conduct analyses, prepare the data set for transmission to Eurostat and develop multidimensional tables for internal and external users.

b. CENSUS DATA QUALITY
Except for a few isolated cases, the CAPI and CATI method resulted in fully completed questionnaires. The computer applications used enabled controls for completeness and correctness of the data already at the collection stage, also facilitating the use of necessary definitions and clarifications during the questionnaire completion process. A set of detailed questionnaire completion guidelines was developed and delivered during training sessions.

Data appraisal
---------------------------

The preliminary results of the agricultural census were published in February 2011 (basic data at the national level), and then in July 2011 in the publication entitled "Report on the Results of the 2010 Agricultural Census" (in a broader thematic scope, at NUTS3 2 level). The final results of the AC 2010 were disseminated by a sequence of publications, covering the main thematic areas of the census. The reference publications were released in paper form, and are available online (www.stat.gov.pl <http://www.stat.gov.pl>), and on CD-ROMs.

摘要
---------------------------
农业普查与农业生产方法调查是在同一组织结构下，同时进行，并使用单一电子问卷以及相同的数据收集和处理方法联合进行的。农业普查涵盖了约180万块农业用地。在所有参加普查的农场中，受访者被询问关于“劳动力从事的其他有偿活动”（OGA）。整个调查的框架是在为普查准备的持有者名单的基础上制定的。在创建名单时，首次采用了面向对象的方法，即在第一阶段识别持有者（对象），定义其坐标（在空间上定位），并基于行政数据识别其持有者。为了国内目的，将面积最小的农场以及那些经济重要性较低（满足非常低的国家级门槛）的农场纳入了与普查联合进行的样本调查。根据《欧盟条例》（EC）1166/2008规定的精确度要求，对约20万块农场的农业生产方法进行了调查。为农业普查准备的框架被用作抽样框架。

统计单位是农业持有者，定义为“包括森林土地、建筑物或其部分、设备以及构成或可能构成有组织经济单位的牲畜，以及与经营农场相关的权利的农业区域”。区分了两种类型的持有者：（i）自然人的持有者（对此类持有者适用门槛）和（ii）法人的持有者（不适用门槛）。
数据类型
---------------------------
普查/统计数据 [cen]
抽样程序
---------------------------
（a）框架
农业普查和农业生产方法调查的框架基于农业持有者名单。在为2010年AC和SAPM的需求创建农场名单的过程中，首次采用了客观方法，即在工作的第一阶段，识别了农业持有者，定义了其坐标（农场在空间上定位），并根据以下所述的行政数据确定了其持有者。名单的创建始于识别所有用于农业目的的土地地块。在农业结构调整和现代化局（包括持有者记录和生产者记录）中找到的土地地块被合并成持有者，并确定了其持有者。对于其余土地地块，持有者根据土地和建筑物记录进行确定，之后通过不动产税记录集更新了关于用户的数据。
数据收集方式
---------------------------
计算机辅助个人访谈 [capi]
研究工具
---------------------------
使用单一电子问卷进行数据收集，结合了与2010年AC和SAPM相关的信息。普查涵盖了WCA 2010推荐的16个核心项目。
问卷：
第0节.识别特征
第1节.土地利用
第2节.经济活动
第3节.收入结构
第4节.播种和其他区域
第5节.牲畜
第6节.拖拉机、机器和设备
第7节.肥料使用
第8节.劳动力
第9节.农业生产方法
数据清理操作
---------------------------
（a）数据处理和存档
通过CAPI、CATI和CAWI渠道捕获的数据被收集到为AC 2010建立的运营微观数据库（OMB）中，并在那里进行处理（包括数据控制和纠正，以及使用从行政来源、推定单位和SAPM估计中获得的数据完成在AC中获得的数据文件）。在OMB中脱敏和验证的数据被导出到分析微观数据库（AMB）中，以进行分析、准备数据集以传输到欧盟统计局以及为内部和外部用户开发多维表格。
（b）普查数据质量
除了少数孤立案例外，CAPI和CATI方法导致了问卷的完全完成。所使用的计算机应用程序在收集阶段就允许对数据的完整性和正确性进行控制，同时也促进了在问卷完成过程中使用必要的定义和解释。一套详细的问卷完成指南被开发并在培训课程中提供。
数据评估
---------------------------
2010年农业普查的初步结果于2011年2月发布（国家级的基本数据），然后在2011年7月，在名为“2010年农业普查结果报告”的出版物中发布（在NUTS3 2级别的更广泛主题范围内）。AC 2010的最终结果通过一系列出版物传播，涵盖了普查的主要主题领域。参考出版物以纸质形式发布，可在网上（www.stat.gov.pl <http://www.stat.gov.pl>）和CD-ROM上获取。
