Abstract
With the objective of providing Information on the impact of Tsunami on Sri Lanka for better planning rebuilding of systems and rehabilitation of those affected, DCS conducted a Census of Tsunami on Feb 2005 to provide unbiased and reliable information on this event. The complexity of the situation was very high and DCS realized this as a tough task. The Census was conducted in two stages. During the stage 1, all the building units in the affected Census Blocks were listed under three categories. In stage 2, detailed information was collected from both damaged housing and non housing units using a separate questionnaire.
This dataset belongs to the stage 1 of the project whose purpose was to enumerate the housing units of the Tsunami affected areas and classify them by type of damage - ie totally damaged, partially damaged (restorable), partially damaged (un-restorable), undamaged.
The type of damage was taken as the nature of damage caused to a housing unit when it was directly hit by the Tsunami wave. For completeness, the undamaged housing units also had been counted.

Data Collection Notes
Definition of the Buffer Zone:
The definition for measuring Buffer Zone had been set to cover the area from the sea coast to the boarder up to which the Tsunami wave directly hit the land. The tidal wave hit by other means such as from the Harbor, the Bay, the river, the Lagoon etc had to be considered.
Un-cleared area - Controlled by the LTTE
Certain areas in the North and east have been identified as the areas controlled by the LTTE, when the peace accord was signed in the year 2002. Officers of DCS were allowed to enter those areas by the LTTE in the listing operation of collecting information by type of damage.
DCS has identified all the Grama Niladhari Divisions in each District affected by Tsunami (Already all such Divisions have been marked on electronic maps)
The lists (F1 Form) of housing units and other buildings (prepared for the census 2001) pertaining to the affected census blocks of the affected GN Divisions have been extracted and photocopied from the available records.
A GN division is subdivided into several Census Blocks(CB). Each CB has about 80 housing units in the Urban areas and about 65 units in the Rural/Estate areas. Lists of H/units for each CB with sketch map were prepared and stored in the DCS for conducting surveys. This map includes building type (housing unit, other building etc), serial number of the unit. This unit is called F1 form. About 125 000 F1 forms are drawn for the entire Sri Lanka. Before any survey this list has to be updated.
F1 form has the following Basic Info:
Census Unit No
Postal Address
Chief Occupant's name
Whether Housing unit, Collective living quarters, institution/non housing unit)
No of persons usually spending the night
The economic activity of the members residing in the unit
Whether they have land outside
Whether they do fishing

Data Processing
Other Processing
The data collected in the forms were fed into Excel in a central location (DPU). Having completed the data entry a round of manual checking was conducted and errors were corrected.
Separate files were maintained for each DS Division in each District. The Division wise files had data entered either in Sinhala font or in English font. In the predominantly Sinhala speaking areas the forms were filled in Sinhala and the data was entered using Sinhala font. in Excel. For others the forms were filled in English and the data were fed in English.
The Divisional files were consolidated and a District file was prepared for all 13 Districts for archival purposes. Original Data (unconsolidated data ) in the form of District-wise zip files are available in the external Resources Section.
