Information was collected from 20 Districts (Excluding 5 districts in the Northern Province -\nJaffna, Kilinochchi, Mannar, Vavuniya and Mullativu). Composition of the provinces is given below.\n\n1 Western Province: Colombo, Gampaha, Kalutara\n2 Southern Province: Galle, Matara, Hambanthota\n3 Sabaragamuwa Province: Rathnapura, Kegalle\n4 Uva Province: Badulla, Moneragala\n5 Central Province: Kandy, Matale, Nuwara - Eliya\n6 Eastern province: Ampara,Batticaloa,Trincomalee\n7 North-Central Province: Anuradhapura, Polonnaruwa\n8 North-Western Province: Puttalama, Kurunegala\n\nThe SLDHS used a stratified two-stage sample design. The sample was spread geographically in\nproportion to the population. The first stage involved selecting  2500 enumeration areas (clusters)\nfrom the list of about 100,000 enumeration areas (EAs) formed in the 2001 Population Census, in\norder to provide reasonably accurate estimates by National Level, Sector Level and District Level, and\nto provide estimates for Tsunami affected areas as well.\n\nAn enumeration area is a sub division of a Grama Niladari Area which consists of about 80 housing\nunits in urban areas and about 65 units in rural or estate . The criteria used in the subdivision is that\none enumerator can visit all the units in the area within six hours to take a count of all the units and\nthe people residing therein .Lists of all these EAs (including information of housing units ) with a\nmap is available at DCS to be used as a frame for selection of samples for surveys.\n\nThe second stage of selection involved the systematic sampling of 10 households listed in each\nEnumeration Area. Thus the survey covered a total of 2500 clusters: 447 urban, 1818 rural and 235\nestate. Finally information was collected from 2,106 clusters while remaining 394 clusters were not\nenumerated (clusters from the Northern Province and few clusters from other areas) due to various\nreasons.\n\nAll ever married women aged 15-49 years and their children below 5 years of age at the time of the\nsurvey were eligible to be interviewed. They were either usual residents of the households or visitors\npresent in the household on the night before the interview date.","sampling_deviation":"The survey covered all parts of the country excluding the Northern Province.","coll_mode":["Face-to-face [f2f]"],"research_instrument":"A  questionnaire was used to collect information from households and eligible women. Information\nwas collected through personal interviews. Model questionnaires developed by MEASURE DHS\nwere used with some modifications to match the local situation.\n\nAdditional questions were also included to satisfy the needs of the health sector and also to provide\ndata for the compilation of Multiple Indicator Cluster Surveys (MICS) and Millennium Development\nGoals (MDG) indicators. The complete questionnaire was pre-tested by a team of well experienced\nstaff to test the feasibility, sequence, skipping and timing before it is being finalized. The\nquestionnaire was prepared in Sinhalese and Tamil languages mainly,  and the  English version was used\noccasionally.\n\nThe questionnaire consisted of two sections namely household section and women's section. The\nhousehold questionnaire served dual purposes. One was to list all the usual members and visitors in\nthe selected household together with some basic information such as age, education, marital status,\n\nInformation such as Nature of residence, relationship to the head of household, some information about non communicable diseases, inadequacy of basic requirements of school going children and information about orphan-hood were used to identify eligible women and children for main interviews and also\ngives an estimate of the sample population to be used as denominators for some of the household\ncharacteristics. The second purpose was to collect information on characteristics of the household's\ndwelling unit, such as the source of drinking water, type of toilet facilities, materials used for the floor\nand roof of the house, tenure, garbage disposal, ownership of various durable goods, use of iodized\nsalt and use of mosquito nets including treated nets.\n\nThe woman's questionnaire was used to collect information from all ever married women aged 15-49\nyears and covered the following topics:\n\n\u2022 Background characteristics (education, marital status, media exposure, etc.)\n\u2022 Anthropometric measurements and hemoglobin levels\n\u2022 Reproductive history and child mortality\n\u2022 Knowledge and use of family planning methods\n\u2022 Antenatal, intra-natal, post-natal care and breastfeeding practices\n\u2022 Vaccinations, childhood illnesses and nutrition status of mothers and children\n\u2022 Marriage and sexual activity\n\u2022 Fertility preferences\n\u2022 Woman's work and husband's background characteristics\n\u2022 Awareness about AIDS and other sexually transmitted infections (STIs)\n\u2022 Use of drugs, alcohol by household members and other health issues\n\nIn addition calendar of events related to eligible respondent's marriage, child births, information with\nregard to contraception was recorded in a specially designed chart for a five year period prior to the\nsurvey.","coll_situation":"A total of 24 teams (15 Sinhala teams and 9 Tamil teams) were formed for the data collection. Each\ncomprised of one female supervisor, four female interviewers, one field editor, measurer (height and\nweight and GPS measurements) and field assistant. The Senior staff of DCS was appointed as District\ncoordinators and each was assigned to accomplish the co-ordination work of the teams. The overall\nresponsibility of the coordinators was to assure the smooth functioning of field work. This included\nthe checking of filled questionnaires for quality control and also to attend to other logistics such as\ntransport, accommodation etc. Data collection in areas other than the Eastern Province started in\nSeptember 2006 and continued for 5 to 7 months. During this period field work had to be stopped\ntemporarily for a period of about one month due to the heavy rainfall in most parts of the country. The\nfield work of areas covering Tamil speaking communities started much later due to various reasons.\nThe field work which started in May 2007 continued up to October 2007","act_min":"Instructions  were  given  to  the  interviewers  to  ensure  that  every  question  has  been  answered  and  the  response  recorded  correctly  before  leaving  the  household.

The  coordinators  visited  the  interviewers  in  the  field  both  at  the  beginning  and  in  the  middle  of  the  fieldwork  and  reviewed  the  questionnaires completed  by  every  interviewer  for  the consistency  of  the  response.","cleaning_operations":"The processing of the SLDHS data began a few weeks after the fieldwork commenced. Completed\nquestionnaires were returned periodically from the field to the Data Processing Division in Colombo,\nwhere they were coded manually by specially trained staff for this task.

All data were entered twice (100 percent verification). \nThe concurrent processing of the data was a distinct advantage for data quality, since the Survey Unit was able \nto advise field teams of errors detected during data entry.
