While auto sales hit 17.5 million in 2015, slightly surpassing the prior record set in 2000, the US population is now 12.7% larger! Per capita sales are falling because the percentage of persons with driver’s licenses is declining. The percentage with a license aged 20 through 24 is 77%, down from 80% in 2011 and 92% in 1983. For those under 20, the declines are steeper. Suburbia take note!
