Sample Vital Registration System

Sample Vital Registration System

Sample Vital Registration System (SVRS) Project is a regular surveillance system undertaken by the Bangladesh Bureau of Statistics to determine the annual population change at national and district level. The objective of the Sample Vital Registration System of BBS is to collect, compile and publish demographic data to meet the inter censual data needs of our valued stakeholders. Over the years, the vital registration system has been improved and the sample coverage has been increased to estimate reliable demographic indicators at the sub national levels. The strength of the sample vital registration system is the collection of data under a dual record system to estimate demographic indicators using Chandrasekaran and Deming Technique. Under this system vital events are collected as and when it occurs by a locally recruited registrar termed as Local Register (LR) (System-1). On the other hand, under a second system another group of officials from Upazila Statistical Office of BBS also collect the data from the same area on quarterly basis (system-2). Having the filled up questionnaires from the two systems, data are matched in the headquarter by a pre-designed matching criteria and the demographic rates and ratios are calculated using Chandrasekaran and Deming Technique.
