Abstract
Summary
This dataset provides detailed information about the enumeration areas used for the 2022 Population and Housing Census (PHC) in Tanzania. The data was collected from 2020 to May 2022 and is available in ESRI Shapefile format, including geographic boundaries and key attributes of each ward area. The dataset aims to support census planning, management, and analysis by offering crucial insights into population distribution and characteristics.
Purpose
The primary purpose of this dataset is to serve as a geographical reference for the ward areas used in the 2022 PHC. It aims to aid various census activities, including demographic analysis, ward area allocation, and strategic planning. The dataset is intended to improve the accuracy and efficiency of census operations by providing precise and up-to-date geographic information.
Data Structure
The dataset is provided in the ESRI Shapefile format, a popular vector data format for Geographic Information System (GIS) applications.
Geographic Coverage
The dataset covers the entire geographic area of Tanzania. The boundaries of the ward areas are drawn according to administrative regions and internal geographical features.
