Title: Weekday-Basis Seasonal Factors: Auto Production Series ID: G17MVSFWAUTOS Source: Board of Governors of the Federal Reserve System (US) Release: Seasonal Factors for Domestic Auto and Truck Production Seasonal Adjustment: Not Seasonally Adjusted Frequency: Monthly Units: Seasonal Factor Date Range: 1996-01-01 to 2025-06-01 Last Updated: 2024-03-18 1:29 PM CDT Notes: A seasonal factor measures the percentage amount that on average, monthly production is above or below normal. A seasonal factor of 120 states that the month in question will usually be 20% above an average month's production level. Similarly, a seasonal factor of 100 implies an average month, while a factor of 80 implies a month that is typically 20% below average. The not seasonally adjusted (NSA) data for auto assemblies (https://fred.stlouisfed.org/series/MVAAUTOASN) are obtained from Ward's Communications, the weekly-basis seasonal factors (SFW), which contain adjustments for holiday and length-of-month effects as well as normal seasonal variation, and the number of production days, or weekdays in a month (https://fred.stlouisfed.org/series/G17MVSFWWKDAYS), are applied to MVAAUTOASN (https://fred.stlouisfed.org/series/MVAAUTOASN) using the formula found here (https://www.federalreserve.gov/releases/g17/mvsf.htm).
