Sri Lanka is all set to conduct its first post war island wide census next year for the first time in three decades. <br/><br/>The last Census of Population and Housing was conducted in 2001 but the process could not be extended to the North and Eastern parts of the country that were under the control of the LTTE.<br/><br/>Sri Lanka's population is estimated at around 21 million but the exact figure would be known only after the 2011 census. <br/><br/>The door-to-door survey will be conducted by a strong workforce of nearly 80,000 enumerators, district administrative officers, and other ground-level officials.<br/><br/>The previous completed census country wide count was held in 1981.
