Agricultural census, 2010 - Réunion

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

The Statistical and Forecasting Service has been entrusted with the production of the AC 2010. (SSP) which is the central statistical department of the Ministry in charge of agriculture, (MAAPRAT) the central department is in charge of the design of the operation, the drafting of the questionnaire and instructions, the training of regional services, the final quality control of the data collected and of the first publication of the results. The SSP has relied on its specialised decentralised levels, the services regional statistics (NUTS2) of statistical and economic information (SRISE). The threshold definition of agricultural holding applied has been the same since 1955, and corresponds exactly to the one proposed by the European regulation. The geographical area is the whole of France; for the DOM the territories of Saint-Martin and Saint-Barthélemy are now excluded, Mayotte is not yet included.

For statistical purposes, agricultural censuses in French territories (French Guyana, Guadeloupe, Reunion and Martinique) are recorded separately in the World Census of Agriculture Database. The census results are presented for all of France.

Analysis unit

Universe
---------------------------

The statistical unit in the AC 2010 was the agricultural holding, defined as an economic unit that participates in agricultural production and meets the following criteria:
· it has an agricultural activity either of production, or of maintenance of the lands in good agricultural and environmental

Kind of data
---------------------------

Census/enumeration data [cen]

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

a. Frame
The basic list of agricultural holdings was built using the SSP farm register, the SIRENE register (business register), the list of farmers who had applied for aid (area declarations),' and some additional sources for beekeeping, olive oil, aromatic plants. The holding lists were checked at local level by communal commissions.

b. Complete and/or sample enumeration method(s)
The AC and SAPM were conducted using complete enumeration.

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

Computer Assisted Personal Interview [capi]

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

Three questionnaires were used: one for France in Europe (including questions of regional interest) and two for France's overseas territories: one for Guadeloupe, Martinique and Reunion and another for Guyana. The census covered all 16 core items recommended in the WCA 2010. ie.

0001 Identification and location of agricultural holding
0002+ Legal status of agricultural holder
0003 Sex of agricultural holder
0004 Age of agricultural holder
0005 Household size
0006 Main purpose of production of the holding
0007 Area of holding according to land use types
0008 Total area of holding
0009 Land tenure types on the holding
0010 Presence of irrigation on the holding
0011 Types of temporary crops on the holding
0012 Types of permanent crops on the holding and whether in compact plantation
0013 Number of animals on the holding for each livestock type
0014 Presence of aquaculture on the holding
0015+ Presence of forest and other wooded land on the holding
0016 Other economic production activities of the holding's enterprise

Cleaning operations
---------------------------

a. DATA PROCESSING AND ARCHIVING
The CAPI interface included controls to ensure that there were responses to all questions. In addition, interactive range and consistency checks were included for each variable so that corrections could be made by the enumerator during the interview. Further edits and imputations were completed at the central office where the census validation and tabulation was completed. To ensure that the list of holdings was complete, several tests were conducted at the end of collection. All available administrative sources were used to verify that existing holdings had been identified and included. The key databases and registers used included that for EU agriculture aid applications, the national database of bovine identification, the computerized vineyard register, organic producer records, and some local registers for small productions. The data, after validation, were archived on secured servers.

b. CENSUS DATA QUALITY
To assess the quality of field data collection, completeness checks and feedback were performed at the end of field data collection operation, from March to June 2011. Data checking began during the collection phase on the farmer's premises. It then continued throughout the processing chain. A special effort was made to check the AC's coverage by using the administrative data available. The nonresponse rate was of only 0.96 percent, and the missing data were imputed using the hot deck method.

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

The first provisional census results were disseminated in September 2011, ten months after the end of the reference period. The main final results were made available at the end of February 2012, 16 months after the end of the reference period. The AC 2010 results were disseminated online and are available on the SSP website.9 The "ADEL" tool allows web users to build their own tables.

The first table with main results shows the total number and area of holdings broken down by continental France, on one hand, and its overseas territories, on the other. See metadata review tables in external materials.

摘要
---------------------------
统计与预测服务承担了生产AC 2010（SSP）的重任，该服务是负责农业的中央统计部门（MAAPRAT）的核心部门，负责操作设计、问卷及说明的起草、区域服务的培训、收集数据的最终质量控制以及结果的首次发布。SSP依靠其专业化的分散层级，即区域统计和经济学信息服务（NUTS2）。自1955年以来，所采用的农业经营门槛定义一直保持不变，与欧洲法规提出的定义完全一致。地理区域涵盖整个法国；对于DOM，圣马丁和圣巴泰勒米领土现已排除在外，马约特尚未纳入。

对于统计目的，法国领土（法属圭亚那、瓜德罗普、留尼汪和马提尼克）的农业普查记录在世界农业普查数据库中分别记录。普查结果展示在法国全境。

地理覆盖范围
---------------------------
全国覆盖

分析单元
---------------------------
家庭

总体
---------------------------
AC 2010的统计单元是农业经营，定义为参与农业生产并满足以下标准的经济单位：
·拥有农业生产或维护土地以保持良好的农业和环境状态的活动。

数据类型
---------------------------
普查/枚举数据 [cen]

抽样程序
---------------------------
a. 框架
农业经营的基本名单是通过SSP农场登记册、SIRENE登记册（企业登记册）、申请援助的农民名单（面积申报）以及一些额外的蜜蜂养殖、橄榄油、香草植物来源构建的。经营名单在地方层面由地方委员会进行检查。
b. 完整和/或样本枚举方法
AC和SAPM使用完整枚举进行。

数据收集方式
---------------------------
计算机辅助个人访谈 [capi]

研究工具
---------------------------
使用了三份问卷：一份用于欧洲的法国（包括区域兴趣问题），以及两份用于法国海外领地：一份用于瓜德罗普、马提尼克和留尼汪，另一份用于圭亚那。普查涵盖了WCA 2010推荐的16个核心项目，即：

0001 农业经营的识别和位置
0002+ 农业经营者的法律地位
0003 农业经营者的性别
0004 农业经营者的年龄
0005 家庭规模
0006 经营单位生产的主要目的
0007 按照土地利用类型划分的经营单位面积
0008 经营单位总面积
0009 经营单位上的土地权属类型
0010 经营单位上的灌溉情况
0011 经营单位上的临时作物类型
0012 经营单位上的永久作物类型及其是否为密集种植
0013 经营单位上每种牲畜类型的动物数量
0014 经营单位上的水产养殖情况
0015+ 经营单位上的森林和其他林地情况
0016 经营单位企业的其他经济生产活动

数据清洗操作
---------------------------
a. 数据处理和归档
CAPI界面包括控制以确保对所有问题的回答。此外，每个变量都包括交互式范围和一致性检查，以便在访谈过程中由调查员进行更正。进一步的编辑和补录在中央办公室完成，该办公室负责普查验证和制表。为了确保经营名单的完整性，在收集结束后进行了几次测试。所有可用的行政来源都被用来验证已识别并包含现有的经营单位。关键数据库和登记册包括欧盟农业援助申请数据库、国家牛只识别数据库、计算机化的葡萄园登记册、有机生产者记录以及一些小规模生产的地方登记册。经过验证的数据存档在安全服务器上。
b. 普查数据质量
为了评估现场数据收集的质量，在2011年3月至6月结束的现场数据收集操作结束后进行了完整性检查和反馈。数据检查在收集阶段在农民的场地上开始，然后在整个处理链中继续进行。特别努力使用可用的行政数据来检查AC的覆盖范围。非响应率仅为0.96%，缺失数据使用热补丁法进行补录。

数据评估
---------------------------
首次临时普查结果于2011年9月发布，距参考期结束十个月后。主要最终结果于2012年2月底发布，距参考期结束16个月后。AC 2010的结果已在线发布，可在SSP网站上找到。'ADEL'工具允许网络用户构建自己的表格。
