Provide a Fermi decomposition to answer the following question: How many new pickup trucks are sold each year in the United States? In answering the question, provide commentary as to each step and the assumptions/decisions made to advance the solution.

Comment: Think of \"new pickup trucks\" as those sold through dealer networks to their first owner.

Solution

on an average in US,

total vehicles(four or more wheelered) sold in an year = 18,000,000

trucks covers 55% of the sales = 9,900,000

and among them pickup trucks cover 15-17% of truck sales = 1,683,000

according to reports, there has been 11-13% increase in pickup vehicles sales

that is equal to 1,901,790

population increase rate is 0.77% of 320,000,000

therefore,

expected pickup trucks sale per year = 2,200,000 approx.
