An economic historian is studying the development of a specific region. The data shows that for nearly a thousand years, from 800 AD to 1750 AD, the average output per person remained virtually unchanged. However, starting around 1750 AD, the data reveals a dramatic and sustained rise in output per person that has continued to the present day. Based on this information, evaluate the claim that this region's economic growth follows a 'hockey stick' trajectory. Justify your conclusion by referencing the specific characteristics of the data pattern described.
