Information about data cleaning and normalization
Data Cleaning: All organization names and locations have been normalized to ensure consistent case, remove extra whitespace, and standardize common prefixes/suffixes.
Location Normalization: Variations of the same location (e.g., "Preston", "Preston, Lancashire") have been consolidated into a single canonical form.
Duplicates: Entries with the same organization name and location (after normalization) are counted only once.
About This Data
This visualization shows the distribution of Home Office Worker and Temporary Worker license sponsors across UK towns and cities. The data is sourced from the UK government's official statistics.
Data Cleaning: All organization names and locations have been normalized to ensure consistent formatting. This includes standardizing case, removing extra whitespace, and handling common prefixes/suffixes. Duplicate entries (same organization in same location) are counted only once.
Hierarchical Navigation: The map supports three levels of navigation:
1. Regions (e.g., North West)
2. Major Cities (e.g., Preston, Manchester)
3. Specific Locations (individual towns and cities)
Performance Optimization: The map now processes data in chunks to prevent browser freezing, and uses efficient caching to speed up geocoding operations. For very large datasets, some low-count locations may be filtered to improve rendering performance.
