The OHI results are shown on the exclusive economic zone (EEZ) of each coastal country, an area that extends 200 nautical miles (370 KM) offshore from the country’s coast. For countries with multiple and separate coastlines, EEZs were grouped based on country, latitude, habitation, and ocean basin.

When a goal is not relevant to a specific region, no value (N/A) is shown and that goal is not included in calculation of the region's overall Index score.
