The city planning commission for New Orleans divided the city into 13 planning districts and 73 distinct neighborhoods in 1980. Although initially in the study 68 neighborhoods were designated, and later increased by the City Planning Commission to 76 in October 2001 based in census data, most planners, neighborhood associations, researchers, and journalists have since widely adopted the 73 as the number and can even trace the number back to the early 1900s. While most of these assigned boundaries match with traditional local designations, some others differ from common traditional use. This is a result of the city planning commission's wish to divide the city into sections for governmental planning and zoning purposes without crossing United States census tract boundaries. While most of the listed names have been in common use by New Orleanians for generations, some designated names are rarely heard outside the planning commission's usage.
