The mission of this project is to analyze how state population size influences used car prices across different regions in the U.S. By merging used car listing data with state population trends from 2010 to 2019, I aim to identify patterns in vehicle pricing. This analysis will help us understand whether more populated states tend to have higher or lower car prices and if population data can be a useful factor in predicting pricing trends. Ultimately, this analysis could guide buyers on where to find more affordable used cars and highlight the impact of regional demand on vehicle costs.
