In CHDSS since 2004 data on socio-demographic and health indicators including birth, death, migration, marriage, maternal health, education and employment have been systematically collected and recorded from 7,042 households, randomly chosen from the total of 26,979 households through quarterly household visits by a team of surveillance workers (SWs) with supervision from a team of two supervisors. In 2011 data collection system was modified choosing 49 villages randomly from a total of 183 which were divided into 14 work areas and 14 SWs were recruited from their residing areas. Most of the households included in the system prior to this modification were also included in the new system. The modification of the system has resulted the visit by SWs almost double the number of households, saving time spent on travel in comparison with the previous system. In addition, the modification allowed the possibility of estimating migration as the system includes complete villages. Currently, surveillance covers 82,160 individuals (16,272 households). The primary objective of CHDSS is to monitor the changes in socio-demographic indicators, inequalities in health and impact of public health interventions. A demographic change was accompanied by a shift from traditional to modern society during the past decade, but inequality in health still persists. The findings from the surveillance are shared regularly among the local and global communities. Data are also available upon request to ICDDRB and INDEPTH for use by researchers and policy makers. Bangladesh Chakaria is one of the 500 upazilas (sub-districts) in Bangladesh. It is located between latitudes 21o34' and 21o55' North and longitudes 91o54' and 92o13' East in the southeastern coast of the Bay of Bengal. Administratively, it is under Cox's Bazar district with an estimated population of 511,861 in 2013. The highway from Chittagong to Cox's Bazar passes through Chakaria. The east side of Chakaria is hilly, while on the west side towards the Bay of Bengal is lowland. The Chakaria HDSS covered 11 unions, namely Baraitali, Kaiarbil, Bheola Manik Char, Paschim Boro Bheola, Shaharbil, Kakara, Harbang, Purba Boro Bheola, Surajpur Manikpur, Konakhali, and Dhemoshia. Individual Although Chakaria HDSS started in 1999, covering 183 villages of 166,405 individuals living in 26,979 households, data collection was interrupted during 2001-03. Since 2004, quarterly data collection has resumed, and data have been systematically collected from 7,042 households, randomly chosen from the total of 26,979 households. Data have been collected through quarterly visits by a team of surveillance workers (SWs) with supervision from a team of two supervisors. On a typical day, prior to 2011 a SW would come to the office and take a list of households assigned by the supervisors, travel to respondents' households, update the events and return the collected data sheets to the office. Using this system, data collection and data management took a significant amount of time and money, involving daily travel to the households by SWs. The above system of data collection was modified in 2011. The modification involved choosing 49 villages randomly from a total of 183. The 49 villages were divided into 14 work areas and 14 SWs were recruited from the 14 work areas where they resided. Most of the households included in the system prior to this modification were also included in the new system. The modification of the system has resulted in the SWs visiting almost double the number of households in comparison with the previous system, saving time spent on travel in the earlier system. In addition, the modification allowed the possibility of estimating migration as the system includes complete villages. Event history data So far, all the important demographic indicators related to fertility, mortality, migration and nuptiality have been measured. Information on causes of deaths and migration are also collected and tabulated. In addition, indicators of special interest such as hunger, water and sanitation, use of family planning, use of safe delivery services, immunization, health-seeking behaviour, use of iodized salt, consumption of tobacco, nutritional anthropometry, ownership of mobile phone and household socio-economic condition have been collected when felt appropriate. Socio-economic inequities for the major health and demographic indicators have always been assessed and published. Surveillance workers Supervisors Collection of data from households on a quarterly basis This dataset is related to the demographic surveillance population as a whole Not applicable Proxy Respondent [proxy] Data have been collected through quarterly visits by a team of surveillance workers (SWs) with supervision from a team of two supervisors. On a typical day, prior to 2011 a SW would come to the office and take a list of households assigned by the supervisors, travel to respondents’ households, update the events and return the collected data sheets to the office. The above system of data collection was modified in 2011. The modification involved choosing 49 villages randomly from a total of 183. The 49 villages were divided into 14 work areas and 14 SWs were recruited from the 14 work areas where they resided. Two supervisors supervised the data-collection process. To detect any anomalies, the supervisors re-visited 5% of the households, chosen randomly, within 2 days of data collection by the field workers. Later on, the supervisors and the relevant field workers together sorted out any inconsistencies in the collected data. All the filled-up questionnaires were manually checked for completeness and for any inconsistencies. Not applicable All the filled-up questionnaires were manually checked for completeness and for any inconsistencies. Subsequently, computer-based data-editing procedures were applied to ensure the quality of data. On an average the response rate is 99.99% in all rounds over the years.
