Younger persons are still less likely to have a driver’s license than in the 1980s

Green Car Congress

Since 2011 , I have periodically examined changes in the proportion of persons with a driver’s license as a function of age. The previous study compared data for 1983 (as the baseline) with those for 2008, 2011, 2014, and 2017. That was followed by modest increases in the licensure for all age groups between 2014 and 2017.

Further reduction in licensing of young drivers during the pandemic

Green Car Congress

In 2011 , Brandon Schoettle and I documented the fact that, during the 25-year period from 1983 to 2008, there was a large reduction in the proportion of young persons with a driver’s license, and an increase in the licensing of older persons. Licensing of older persons—those 60 and older—increased.

Green Car Congress

In a 2011 article , Brandon Schoettle and I showed that the proportion of young Americans aged 16 to 39 years with a driver’s license decreased substantially from 1983 to 2008.
