Shovels includes industry classification data for contractors, though this data has important limitations to understand.
Available Classification Fields
| Field | Description |
|---|
| NAICS | North American Industry Classification System codes |
| SIC | Standard Industrial Classification codes |
| Primary_industry | General industry classification |
Data Sources
Business industry classifications come from self-reported data, typically through:
- Business registration
- Insurance-related transactions
Important Limitations
Self-Reported Nature
Classifications are self-reported by businesses, not verified by Shovels.
Broad Categories
Classifications are quite broad and may not precisely reflect a contractor’s specialization.
Multiple Classifications
Companies in higher-risk occupations often use multiple industry identifiers to reduce their workers’ compensation insurance liability.
No Central Authority
There is no central authority governing these categories.
The Primary_industry field should be taken with a grain of salt due to these limitations.
NAICS vs SIC
| System | Description |
|---|
| NAICS | More modern and specific classification system |
| SIC | Older system, but more widely adopted |
Both are included in our data because NAICS isn’t as widely adopted as SIC codes.
Better Alternatives
For understanding what a contractor actually does, consider:
- Permit descriptions - What work they’ve actually permitted
- Tags - Shovels-assigned categories based on permit data
- Permit history - Patterns of work they’ve completed
