Compendium of Statistical Concepts and Definitions Foreword The various institutions and agencies that make up the National Statistics System (NSS) are sanctioned by the Census and Statistics Act (Chapter 10:29) of 2007 to collect, analyze, compile, produce and disseminate integrated, relevant, reliable and timely official statistical information in their areas of specialization. The Census and Statistics Act brought about the birth of the Zimbabwe National Statistics Agency (ZIMSTAT), a semi-autonomous agency under the Ministry of Finance and the focal point of the NSS. Within the NSS, ZIMSTAT is also responsible for the coordination, supervision, harmonization and standardization of concepts and definitions to be used in the production of official statistics as laid out in the National Strategy for the Development of Statistics (NSDS) in Zimbabwe 2011-2015. ZIMSTAT developed this Compendium of Concepts and Definitions for use by all stakeholders in the NSS, in recognition of its mandated roles of coordination, supervision and harmonization of concepts and definitions in the production and dissemination of official statistics. The use of this Compendium of Concepts and definitions by all players in the NSS will ensure local, regional and international comparability of Zimbabwe’s statistical products. The Compendium presents the concepts and definitions in alphabetical order under broad subject areas for easy access. An attempt has been made to provide self–contained definitions so that users searching for further items or additional material on a particular item can be minimized. It is greatly acknowledged that most of the concepts and definitions were developed making reference to documents produced under the auspices of the international organizations such as: · International Labour Organization (ILO) · Food Agricultural Organisation (FAO) · European Union (EU) · United Nations Educational, Scientific and Cultural Organisation (UNESCO) · United Nations Statistical Division · Organisation for Economic Co-operation and Development (OECD) · United Nations Environmental Programme · Southern African Development Community (SADC) · Economic Commission for Africa, i Compendium of Statistical Concepts and Definitions · Economic Commission Western African States (ECOWAS) · European Statistics (Eurostat) Reference was also made to other authoritative local, regional and international organizations, with particular reference to compendiums of countries such as Uganda and Tanzania with modifications to suit our environment. Last but not least, ZIMSTAT would like to acknowledge with gratitude the immense contribution made by the African Capacity Building Foundation (ACBF) of providing with financial assistance which facilitated the production of this publication. M Dzinotizei` Director General, ZIMSTAT ii Compendium of Statistical Concepts and Definitions INTRODUCTION The Zimbabwe National Statistical Agency (ZIMSTAT) is the main source of Official Statistics in the National Statistical System (NSS) in the country through censuses and statistical surveys, but the responsibility for producing good quality statistics lies not in the hands of ZIMSTAT alone. Other institutions, such as line ministries, produce administrative data and a variety of other essential statistics. However, according to the Census and Statistics Act of 2007, ZIMSTAT is mandated to play a coordination and supervisory role within the NSS. It has been a concern over the years that producers of statistics in Zimbabwe have been producing statistics that are conflicting. This situation was probably caused by lack of coordination and use of differently defined terms and concepts, and this brought difficulties for researchers, planners and decision makers to decide on which dataset to use. In an effort to ensure the timely production of relevant and standardized quality statistics that are comparable over time, space and across subject matter areas, ZIMSTAT has produced the Compendium of Concepts and Definitions in order to provide statistical concepts and definitions to be used by all producers and users of statistics so as to enhance harmonization in the production of official statistics in Zimbabwe. This publication is summarized into 19 subject matter areas; · General Concepts and Definition · Sampling and Survey Methodology · Population and Housing · Education · Health · Employment · Tourism , Migration and Cultures · Gender · Judicial, Crime and Social Welfare · Living Conditions · Poverty · Economic statistics (National Accounts, External Trade, Prices, Finance, Census of Services, Industry) · Information and Communication Technology (ICT) · Science and Technology iii Compendium of Statistical Concepts and Definitions · Sources of Electrical Energy · Agriculture · Environment · Geographical and Mapping Concepts · Quality Assurance. This is the First Edition of the publication of the Compendium on Concepts and Definitions and is intended to be one of the regular publications for use by Government and other statistical stakeholders in the NSS. This publication was produced with the involvement of various stakeholders within the NSS. Henceforth, the NSS needs to be supported by adequate statistical infrastructure based on well-defined Concepts, Definitions, International Classifications and Methodologies and Standard procedures. It is expected that the Development of Statistical Infrastructure will improve the quality of data and harmonize statistical production processes as well as reduce production costs within the NSS. This initiative will assist to heighten public awareness and confidence among various users in the use of routine and ad hoc Surveys and Census data. It is intended to update this publication after every three (3) years. The time in between will be used to develop concepts and definitions for new subject matter areas and promote discussions, comments and constructive suggestions from stakeholders so as to produce quality statistics needed to facilitate evidence-based policy formulation and monitoring and evaluation of Government’s developmental policies and programmes. The next edition will be produced in 2015. iv Compendium of Statistical Concepts and Definitions Acronyms ABM Agent‐based modeling ACP African, Caribbean and Pacific Group of States ADSL Asymmetric digital subscriber line AGRIBANK Agricultural Bank of Zimbabwe AGRITEX Agricultural, Technical and Extension Services AIDS Acquired immune deficiency syndrome ALS Agriculture and Livestock Survey ARI Acute Respiratory Infection AU African Union AZTA Association of Zimbabwe Travel Agents BCG BasilliCalmetic Guerin BEAM Basic Education Assistance Module BOAZ Boat Association of Zimbabwe BOD Biological Oxygen Demand BOR Bed Occupancy Rate BTS Business Tendency Survey CAPCO Central African Power Corporation CARIM Consortium for Applied Research on International Migration CBR Community‐Based Research CBR Crude Birth Rate CCA Climate Change Adaptation CDMA Code Division Multiple Access CDR Crude Death Rate CDU Curriculum Development Unit v Compendium of Statistical Concepts and Definitions CERT.
