* 1995-2000 values, and projected 2045-2050 values; medium variant of UN 1996a and UN 1996b if available. Data not available from the mentioned sources were taken from Factbook, 1997. Negative growth rates between brackets. ** From Annex D of CZMS, 1990. Includes, cities, harbors, etc.
*** Weighted average of Greek and Turkish parts of the Island.
**** The data correspond to French Polynesia which is somehow intermediate between the other islands of American Samoa (2.81-0.58) and Wallis and Futuna (1.05-0.58).
For population density the current (1995-2000) and projected (2045-50) values are given. Extreme events are volcanoes (VO), cyclones (CY), drought (DR), earthquakes (EQ) and tsunamis (TS). Strong incidence is indicated by capitals (CY) while small letters stand for a minor impact (cy). Data stem from Factbook (1997); UN 1996a, 1996b and 1997; CZMS 1990 and OFDA 1996.
