Series Information
The 2011/12 Business Register (BR) for Tanzania Mainland is the first of its kind since it has integrated and translated the current and future demands of local and international data producers and users.
Abstract
The main objective of the survey was to improve the CRE by collecting necessary inputs that will fulfill the current demands of our stakeholders in their daily activities. Other specific objectives were:
(i) to harmonise all establishment directories produced by other data producers in order to have a National Statistical Directory (NSD) of Establishments;
(ii) to improve the CRE dataset by adding new variables including initial capital investments and their sources, owners and their nationalities, business categories, size of the business (micro, small, medium, large) and annual turnover;
(iii) to improve awareness on the importance of BR among key stakeholders by using Information Communication Technology (ICT) and other means of communications; and
(iv) to ensure the proper use of the BR to all data producers and data users as well as public at large.

Notes
The implementation of the 2012 Baseline survey is an important exercise since the information collected will be used to improve the CRE in order to fulfill the current demands of our stakeholders. The baseline findings will be used to develop a database of existing establishments in the country. Unlike, the current CRE, the produced BR will have establishments which are registered and active. All establishments with one and above employees will be included in the 2012 Business Register of Tanzania Mainland.
The updated Business Register (BR) Report will provide quality and adequate sampling frame for establishments' based survey. This will facilitate planning and decision making within the government, the business community, Institutions and other stakeholders. Moreover, will stimulate research and inform public debate through the provision of relevant, reliable and timely statistics and a quality statistical service in general.
