Comments on Mulligan's 'Revisiting the urbanization curve'

摘要

In a recent paper published in this journal, Gordon Mulligan has presented a methodology for better understanding the general pattern of urbanization, familiar as an S-shaped curve. While we agree with most of the statements made by the author, his article deviates from Northam's original urbanization curve. Our commentary suggests that the upper limit and speed of change of the urbanization process should be revisited.
