### Subtype Distribution (19 subtypes)

| Subtype                 | Count | Primary Usage                    |
| ----------------------- | ----- | -------------------------------- |
| `retail`                | 202   | Consumer retail establishments   |
| `healthcare`            | 134   | Medical and healthcare services  |

| `technology`            | 2     | Technology services              |

### Critical Issues Identified

1. **Sector-Subtype Confusion**: 699 organizations (54.6%) have identical sector and subtype values
2. **Inconsistent Classification**: Some sectors have very few organizations (agriculture: 2, sports: 2, technology: 2)
3. **Limited Granularity**: Only two levels of categorization
4. **User-Unfriendly**: Categories are not aligned with how users search for services

### Sector-Subtype Relationship Analysis

**Most Problematic Combinations** (where sector = subtype):

- `retail/retail`: 202 organizations
- `healthcare/healthcare`: 134 organizations
- `services/commercial`: 87 organizations (different but related)
- `food_beverage/food_beverage`: 84 organizations

**Well-Differentiated Combinations**:

- `beauty_wellness/personal_services`: 79 organizations
- `education/educational`: 104 organizations
- `automotive/transportation`: 15 organizations
- `religious/cultural`: 9 organizations

---

## Implementation Details

### Database Schema Changes

```sql
-- Add new categorization columns to organizations table
ALTER TABLE organizations ADD COLUMN primary_sector VARCHAR(50);
ALTER TABLE organizations ADD COLUMN business_types JSONB DEFAULT '[]'::jsonb;
ALTER TABLE organizations ADD COLUMN service_categories JSONB DEFAULT '[]'::jsonb;

-- Create indexes for new fields
CREATE INDEX idx_org_primary_sector ON organizations(primary_sector);
CREATE INDEX idx_org_business_types_gin ON organizations USING gin(business_types);
CREATE INDEX idx_org_service_categories_gin ON organizations USING gin(service_categories);
```

### Mapping Logic Example

```typescript
// Legacy to new system mapping
const sectorMapping: Record<string, string> = {
  retail: 'RETAIL_COMMERCE',
  healthcare: 'HEALTHCARE_WELLNESS',
  services: 'PROFESSIONAL_SERVICES', // Will be refined by subtype
  beauty_wellness: 'CONSUMER_SERVICES',
  food_beverage: 'FOOD_HOSPITALITY',
  education: 'EDUCATION_TRAINING',
  automotive: 'TRANSPORTATION_LOGISTICS',
  government: 'GOVERNMENT_PUBLIC',
  religious: 'COMMUNITY_RELIGIOUS',
  manufacturing: 'MANUFACTURING_INDUSTRY',
  financial: 'PROFESSIONAL_SERVICES',
  technology: 'PROFESSIONAL_SERVICES',
};

const subtypeToBusinessType: Record<string, string[]> = {
  retail: ['retail_store'],
  healthcare: ['healthcare_facility'],
  personal_services: ['direct_service'],
  professional_services: ['professional_service'],
  food_beverage: ['food_establishment'],
  educational: ['educational_institution'],
  transportation: ['transportation_service'],
  commercial: ['retail_store', 'professional_service'],
  religious: ['religious_institution'],
};
```
