The biennial National
Census of Ferry Operators (NCFO) is a data collection of all ferry operations
providing service within and to the United States and its territories. The census collects information on the vessels,
terminals, segments that make up our Nation’s ferry system, as well as key operational
information, such as passenger and vehicle boardings. The 2018 NCFO captured that in 2017, there were 967 unique ferry segment
routes reported among 181 operators, connecting 608 unique terminals. These
results can be explored, queried, and downloaded in the interactive map below along with the results of the previous census, the 2016 NCFO.
for the route segments was gathered from a variety of sources. Many were
calculated using Automatic Identification System GPS data obtained from the US
Army Corps of Engineers (USACE). Others were gathered from government agencies,
including the National Oceanic and Atmospheric Agency (NOAA), United States Geological
Survey (USGS), Census Bureau, National Park Service, and the USACE. Routes which could not be sourced
from any of the above were digitized and denoted to have "unofficial
geometry", as demonstrated in the map's legend.
