MARAD's Office of Policy and Plans publishes statistical and economic analyses and reports on a variety of maritime transportation topics.  Published data are used as indicators for the health of the U.S. flag maritime industry.  The Office regularly tracks the number of large, self‑propelled, ocean-going ships registered under U.S. flag, and other statistics on U.S.‑international trade and vessel activity at U.S. ports.  MARAD uses this data to monitor the performance of its programs and to ascertain the effectiveness of meeting agency mission requirements.
