Figure: The residential locations of FIRE and Corporate Service Workers from 1861 to 1906.
These maps show the northward residential movement of different samples of workers employed in the finance, insurance and real estate (FIRE) sector, or who are corporate executives. In all four periods, employment locations remained largely downtown. However, over the 19th century there was significant northward movement of this population. In 1861 the vast majority were living in the area between Houston and 23rd Streets. By 1906, the vast majority of these workers were living on the Upper West Side and the Upper East Side, hugging Central and Riverside Parks. Source: Barr and Tassier (2015).
