The number of dancing schools in New Orleans increased dramatically during the 20th Century. This data was extracted from city directory listings for the years: 1930, 1931, 1935, 1945, 1955, 1962, 1968, 1973, 1977, 1986, and 1997. It is an initial review of directory information and it not an exhaustive representation. According to a preliminary review of the 2021 New Orleans Yellow Pages, there are roughly 56 dancing schools that fit this definition. This is a very cursory review, and a more in-depth scoping of the data is needed.
This google map shows the location of each dancing school/teacher listing in city directories for select years. The pins are color-coded by year (1930-31 are combined.). To toggle the pins by year, slick on the slider icon on the map menu bar's top left corner.
