Purpose of Data Sourcing Explanation
This page explains how residential listing data used for Dar es Salaam is sourced and compiled at a structural level. The objective is to document sourcing mechanics and boundaries without evaluating data quality, completeness, or representativeness.
Platform-Originated Content
Residential listings originate from third-party platforms where contributors publish property information for visibility. The dataset captures only what is publicly observable on these platforms at the time of extraction, reflecting platform-specific formats and disclosure practices.
Contributor Role in Data Formation
Listing content is shaped by contributors who select categories, enter descriptive attributes, and assign location references. The dataset therefore reflects contributor interpretation and intent rather than standardized or verified residential information.
Snapshot-Based Collection
Data sourcing occurs as a snapshot of visible listings rather than as a continuous feed. Listings included represent those active and observable at the time of collection, without indicating duration, persistence, or recurrence of publication.
Exclusions and Structural Gaps
Unlisted properties, informally exchanged housing, and residential assets outside platform ecosystems are structurally excluded from the dataset. These exclusions are inherent to the sourcing method and do not imply absence within the real-world residential environment.
