Census of Population and Housing 2011 - Sri Lanka

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

Planning for the ‘Census of Population and Housing 2011’, 14th National Census of Sri Lanka since 1871 and the first Census since 1981 covering all the districts in the country, was initiated by the Department of Census and Statistics (DCS) in 2008. The preparation of maps at Grama Niladhari (GN) level was completed in 2009/2010 and the listing of the buildings based on these maps was completed in 2011. The enumeration stage of the Census was scheduled for and the activities carried out between 27 February and 21 March 2012. The enumeration stage was comprised of two rounds: the first round, which was carried out from 27th February to 19th March 2012, involved collection of data of persons according to their places of usual residence, and their housing units. The revision of data collected in the first round to account for any births, deaths or changes of residence between the date of collection and the Census Date, which is 20th March 2012, was carried out during the second round, based on a defined Census Moment of midnight of 19th March 2012. Enumeration of the homeless people who do not have a usual place of residence was carried out during the night of 19th March 2012, based on the above Census Moment. About 80,000 enumerators were deployed for data collection. Supervision of these activities was carried out by the Grama Niladharis and other appointed government officials. District Secretaries functioned as Commissioners of Census for their respective districts while the Divisional Secretaries functioned as the Deputy Commissioners of Census for their respective Divisional Secretariat divisions. The necessary technical guidance to conduct the Census was provided by the officers of DCS.

Geographic coverage
---------------------------

An important feature of this Census is the coverage of the entire island after a lapse of 30 years since 1981. Only 18 districts out of 25 districts were covered in the previous Census which was carried out in 2001 due to the conflict situation in Northern and Eastern Provinces prevalent during that period. Census activities in Jaffna, Mannar, Vavuniya, Mullaitivu and Kilinochchi districts in the Northern Province and in Batticaloa and Trincomalee districts in the Eastern Province could not be completed during that Census.

摘要
---------------------------
“人口与住房普查2011年计划”，自1871年以来进行的第十四次斯里兰卡全国人口普查，以及自1981年以来的首次全面覆盖全国所有地区的普查，由人口与统计部（DCS）于2008年启动。在2009/2010年完成了格拉马尼尔达里（GN）级别的地图制作，并基于这些地图在2011年完成了建筑物的登记。普查的统计阶段计划于2012年2月27日至3月21日进行。统计阶段包括两个阶段：第一阶段，从2012年2月27日至3月19日，涉及根据个人通常居住地收集其个人及其住房单位的数据。根据收集日期与普查日（2012年3月20日）之间的出生、死亡或居住地变更等情况，对第一阶段收集的数据进行修订，这一修订工作在第二阶段进行，基于2012年3月19日午夜规定的普查时刻。在2012年3月19日夜间，根据上述普查时刻，对无固定居住地的无家可归者进行了统计。大约有80,000名统计员被部署进行数据收集。这些活动的监督由格拉马尼尔达里和其他任命的政府官员执行。区秘书在各自的地区担任人口普查专员，而地区秘书在各自的地政司地区担任人口普查副专员。人口与统计部的官员提供了进行普查所必需的技术指导。
地理覆盖范围
---------------------------
本次普查的一个重要特征是在1981年以来间隔30年后，对整个岛屿进行了全面覆盖。由于当时北部和东部省份的冲突情况，2001年进行的上次普查只覆盖了25个地区中的18个地区。在北部省份的贾夫纳、曼纳、瓦武尼亚、穆拉蒂维和基洛内奇地区，以及东部省份的巴提卡尔奥和特里尼康姆利地区，那次普查未能完成。
