The census information thus collected provides benchmark data on the structural characteristics of the agriculture sector. It also provides benchmark data for current agricultural statistics and sampling frames for future sample surveys.\n\nThe Census of Agriculture 1982 was one of the largest operations in the field of Production - 1921 was the first attempt that made to conduct a Census in the country followed by parcel Censuses in 1924 and 1929. These Censuses were limited to collect the information such as crop area, production and livestock numbers at village level.  Subsequently, in 1946, 1952, 1962, 1973 and 1982, five Censuses had been conducted.  \n\nThe data collected at the Census have been released over a period of time commencing from February 1983 with the release of some provisional results in respect of the small holding sector.  This was followed by the report on Estate Sector for which data was collected through a mailed questionnaire. A report in respect of the small holding sector based on a ten percent sample tabulation was released in July 1984 to serve the immediate needs of the data users. It was followed by a series of District reports containing detailed information based on the complete tabulation of data in respect of the small holding sector."},"version_statement":{"version":"v1.0: Full edited dataset, for internal DPD use.","version_date":"2008-12-01"},"study_info":{"topics":[{"topic":"agricultural, forestry and rural industry [2.1]","vocab":"CESSDA","uri":"http:\/\/www.nesstar.org\/rdf\/common"}],"abstract":"Although the Census of Population was a regular decennial function since 1871, the Census of Agriculture had not been conducted in such a frequency. A census of Production, virtually Agricultural production was taken in 1921 and was followed by a partial censuses in 1924 and 1929. At these censuses. particulars of crop areas, livestock numbers, and production were recorded at village level.  \n  \nIn more recent times the Census of Agriculture had been conducted in 1946, 52, 62 and 73. At the '46 census, a plot-wise enumeration was undertaken of all blocks of land throughout the country, on which there existed at the time or had previously existed any kind of cultivation. This was the first comprehensive census of agriculture in Sri Lanka in recent times.  \n\nA deviation from this pattern of parcel-wise enumeration was first attempted at the 1952 census, but difficulties in completely enumerating the villages selected in the sample restricted the use of the census data on small holdings. The 1962 census, enumerated all holdings not less than 50 acres on a complete basis and a sample of 10 percent in the case of holdings less than 50 acres. In 1973 the larger holdings and all estates were completely enumerated for detailed information on the various characteristics and operations while a sample of small holdings were scientifically selected and enumerated.","coll_dates":[{"start":"1982-08","end":"1982-08","cycle":"2 weeks"}],"nation":[{"name":"Sri Lanka","abbreviation":"LKA"}],"geog_coverage":"National Coverage Urban, Rural and Estate","analysis_unit":"The basic unit of enumeration was in this census was the operational holding (as distinct from the ownership holding) which was defined as all land and\/or livestock used wholly or partly for agriculture production irrespective of title size legal form or location and is operated under one operational status.","universe":"The Census of Agriculture covered the entire  island excluding the MC's of Colombo and Dehiwela-Mt.

Other holdings were small holdings.\n\nThe census in the small holding sector was carried out in two stages. At the 1st stage the enumerator visited each and every census unit namely housing unit, living quarters other than housing unit and non-housing units in the country and screened out the Agriculture operators thro' a schedule known as Agriculture Census 1 (AC-1). After identifying the agricultural operators, the enumerators collected the following information in respect of their operational holdings through the schedule Agricultural Census - 2 (AC-2).\n\na.\tCharacteristics of the operators - age, sex, educational status\nb.\tType of ownership of holding\nc.\tOperational Status of operator\nd.\tArea of operational holding\ne.\tArea under principal crops.\nf.\tIrrigated and source of irrigation\ng.\tAgriculture machinery owned and used\nh.\tNumbers of livestock kept.\n\nAlong with the first stage census operation, the enumerators were instructed to summarize some important info obtained from AC-2 schedule on a summary sheet AC-4 in order to serve immediate needs of data users.\n\nAt the second stage a sample of 10% of the holdings was selected and the following info was collected thro' AC-3.\n\na.\tPopulation of operator's household\nb.\tSources of income of operator's household\nc.\tMain occupation of the operator\nd.\tType of holding\ne.\tUse of fertilizer and pesticides\nf.\tLand utilization and tenure pattern\n\nThe estate sector was covered thro' a mailed questionnaire AC-5.
