Statistical Estimation of Trends in Scrappage and Survival of U.S. Light-Duty Vehicles
We estimate models of scrappage rates and survival probabilities as a function of vehicle age for U.S. light-duty vehicles. We use counts of vehicles in operation by vehicle type and model year for calendar years 2002-2020, which allows us to estimate scrappage functions for years 2003-2020. We estimate models for three vehicle types: passenger cars,…

A Statistical Analysis of Trends in Light-duty Vehicle Scrappage and Survival: 2003-2020
This report presents the results of statistical models estimating scrappage rates and survival probabilities as a function of vehicle age for U.S. light-duty vehicles. Using vehicle counts by type and model year from 2002 to 2020, the analysis estimates scrappage functions for the 2003–2020 period. Separate models were developed for three vehicle categories: passenger cars,…
