An interactive Tableau dashboard analyzing electric vehicle registrations across model years, states, manufacturers, vehicle types, models, and CAFV eligibility.
The project turns vehicle-level registration data into a business-style analytical view for exploring EV adoption patterns, geographic concentration, manufacturer share, and vehicle mix.
View the interactive dashboard on Tableau Public
- EV registrations by model year
- State-level geographic distribution
- Manufacturer and model share
- Battery Electric Vehicle (BEV) vs Plug-in Hybrid Electric Vehicle (PHEV) mix
- CAFV eligibility distribution
- Average electric range
| Metric | Value |
|---|---|
| Total vehicles | 150,413 |
| BEVs | 116,745 |
| PHEVs | 33,668 |
| Average electric range | 67.83 miles |
These metrics describe the records included in the supplied dataset, not total U.S. EV sales or the current EV market.
- BEVs make up the majority of records, with 116,745 BEVs versus 33,668 PHEVs.
- Tesla has the largest manufacturer share in the dataset.
- Registrations are concentrated in later model years, with the highest displayed point around 2023.
- The dataset is heavily concentrated in Washington State, so geographic conclusions should be interpreted as characteristics of this dataset rather than nationwide EV adoption.
The dashboard helps investigate:
- How does EV registration volume change by model year?
- Which states have the highest number of records?
- Which manufacturers and models dominate the dataset?
- What is the split between BEVs and PHEVs?
- How is CAFV eligibility distributed?
- How does electric range vary across the vehicles represented?
The project uses a vehicle-level Electric Vehicle Population dataset with fields including:
VIN · County · City · State · Postal Code · Model Year · Make · Model · Electric Vehicle Type · CAFV Eligibility · Electric Range · Base MSRP · Legislative District · Vehicle Location · Electric Utility · Census Tract
The source CSV is included in the repository for reproducibility.

This is a portfolio analysis of the supplied registration dataset. It should not be treated as a complete or current representation of the U.S. electric vehicle market.
- Registration counts are not equivalent to total EV sales.
- The dataset has strong geographic concentration, particularly in Washington State.
- Conclusions depend on the completeness and accuracy of the underlying records.
