January 2025 (2025-01) focused on delivering geographic data enrichment and metro-status categorization in BigData2025-Rev/p3, enabling finer geographic segmentation and more reliable downstream analytics. Key work includes adding a Metro_Status column derived from MACCI, establishing metro/region/urban-rural classifications, and hardening DataCleaner with enhanced geographic data handling (column renaming, null value management, and expanded docstrings). The data loader was updated to expose the new geographic columns, ensuring end-to-end consistency from ingestion to analytics. This work improves data quality, enables targeted business insights, and reduces maintenance risk through added documentation and explicit method descriptions. Commits supporting this work include: MACCI value simplification, new column integration into the data loader, improved column calling and null handling, and enhanced method documentation.
