Monthly State Motor Fuel Sales by Fuel Type

United States monthly motor fuel sales data reported by states to the Federal Highway Administration. It includes gallons taxed by states and reported by wholesale distributors, covering highway use, non-highway use, and losses. The data is provided by the U.S. Department of Transportation's Federal Highway Administration and was last updated in February 2026.

Use Cases

• Model state-level fuel consumption trends using the `value` (gallons), `date`, and `fuel_type` columns.
• Analyze geographic disparities in diesel versus gasoline sales by joining `state` or `fips` codes with `fuel_type_code`.
• Forecast monthly fuel tax revenue for state budgets using the `value` column aggregated by `date` and `state`.
• Compare highway versus non-highway fuel use patterns by filtering the `fuel_type` or `fuel_type_code` column.
• Track long-term shifts in fuel type adoption (e.g., special fuels) across states using the `date`, `state`, and `fuel_type` fields.

Strengths

• Data is reported monthly, enabling fine-grained temporal analysis.
• Includes geographic identifiers (`state`, `fips`) for state-level comparisons.
• Covers multiple fuel types (`fuel_type`, `fuel_type_code`) for disaggregated analysis.

Limitations

• Sample size and total row count are unknown, limiting assessment of completeness.
• Data may have reporting gaps or inconsistencies as it is aggregated from state agencies.
• The description does not specify the historical time range covered by the dataset.
