The line graph compares the number of US households with access to a car during the winter and summer seasons over a twenty-year period from 2000 to 2020.
Overall, car ownership was consistently higher in the winter than in the summer throughout the entire period. While both seasons experienced fluctuations, the figures for both winter and summer finished significantly higher in 2020 than they started in 2000, indicating a clear upward trend in household car availability over the two decades.
Looking first at the winter data, the number of households initially fluctuated around the 500 mark between 2000 and 2010. Following a brief decline to its lowest point of approximately 500 in 2005, the figure experienced a sharp increase, ultimately jumping to its peak of around 680 toward the end of the period in 2017.
In contrast, the figures for the summer season were consistently lower but showed a more rapid overall growth rate. At the beginning of the period in 2000, summer car ownership stood at its lowest point of around 250 households. Despite experiencing two separate contractions – declining by a combined total of 150 households between 2005 and 2010, and again between 2018 and 2020 – the general trajectory remained strongly upward. Notably, between 2010 and 2020, the summer figures rose dramatically, with its highest point matching the winter’s lowest baseline of 500.
