Purpose of Update Cadence Explanation
This page explains how dataset update cadence and internal consistency affect the interpretation of residential listing data for Kampala. Its purpose is to clarify the temporal limits of listing-based visibility and to prevent assumptions about continuity, persistence, or change. The focus remains on methodological constraints rather than analytical use.
Update cadence is addressed to ensure that listing snapshots are read as isolated visibility states rather than as continuous records.
Snapshot-Based Update Structure
The dataset is constructed as a series of discrete snapshots, each capturing residential listings as they appeared at a specific moment. Each snapshot reflects what was published and visible at that time, independent of prior or subsequent states.
Listings may appear, change, or disappear between snapshots due to publication behavior, platform moderation, or listing lifecycle dynamics, without any relation to underlying residential conditions.
Consistency Limits Across Updates
Consistency across dataset updates is not guaranteed. Changes in platform taxonomy, publisher behavior, listing templates, or data extraction processes may alter how attributes are recorded or exposed between snapshots.
As a result, differences observed across updates may reflect structural or procedural changes rather than changes in residential reality.
Temporal Interpretation Constraints
Because each snapshot is self-contained, the dataset does not support temporal comparison, trend identification, or inference of movement over time. The absence or presence of a listing in one snapshot cannot be interpreted as entry, exit, or persistence.
Temporal interpretation is therefore constrained to acknowledging that visibility is moment-specific and non-continuous.
Implications for Methodological Use
All references to listing data must treat each snapshot independently. Update cadence should be understood as a technical refresh mechanism, not as a signal of residential dynamics.
This constraint applies uniformly across all modules that reference residential listing visibility in Kampala.
