G17: Seasonal Factors for domestic auto and truck production have been revised
Published on March 18, 2025
Seasonal factors for auto and truck production were revised from January 2020 through September 2026 on March 18, 2025. The revised factors for September 2024 through February 2025 were used in the G.17 release issued on March 18, 2025, and the revised factors for earlier months will be incorporated into the production estimates at the time of the annual revision. The revised seasonal factors are based on production data through January 2025; in the estimation, production data for January 2024 and January 2025 are identified as outliers due to unseasonably cold weather and the impact of snow storms. The seasonal factors are scheduled to be revised again in March 2026.
