Census of Population and Housing 2012 Department of Census & Statistics Ministry of Policy Planning and Economic Affairs i ii Prologue Department of Census & Statistics has successfully completed the 14th Population & Housing Census in 2012. This Census, conducted to cover the whole island after three decades i.e. since 1981, marks an important juncture in the history of conducting Census in Sri Lanka. This publication is the demographic and housing information report prepared based on the final information of the census on Population & Housing of 2012. The report, comprising 12 chapters, initially contains information on the history and importance of Census and how the Census activities were organized. Secondly it deals with the administrative structure of Sri Lanka and the third chapter is on the growth, distribution and trends of population in the country. Henceforth, from 4th to 12th Chapters of the report gives the breakdown of the population by age-sex distribution, status of marriage and fertility, urbanization, internal migratory trends, physical or mental impairments, distribution of the population by race and religion, education, economically active/ non active and information regarding houses inhabited by this population. It is hoped that the contents of this report would be used by the national policy formulators, administrators, researches and intellectuals for the purpose of uplifting the standard of life in this country and also by school children and university students productively for educational purposes. In accomplishing this task my heartfelt thanks go out to, all the officers of the Department of Census and Statistic, the officers of other government institutions who have contributed to Census activity while attending to their own duties, all enumerating officers who collected information and all demographic experts for their suggestions and ideas. Similarly, I also owe a debt of gratitude to all the persons in this country, who are the subject of this Census, for co-operating by providing the required information to make this national endeavour a success.
