certain key sectors (if people are leaving).

information of significance not included elsewhere.

Personal Names - Capitalization: The Factbook capitalizes the surname
or family name of individuals for the convenience of our users who are
faced with a world of different cultures and naming conventions. The
need for capitalization, bold type, underlining, italics, or some other
indicator of the individual's surname is apparent in the following
examples: MAO Zedong, Fidel CASTRO Ruz, George W. BUSH, and TUNKU
SALAHUDDIN Abdul Aziz Shah ibni Al-Marhum Sultan Hisammuddin Alam Shah.
By knowing the surname, a short form without all capital letters can be
used with confidence as in President Castro, Chairman Mao, President
Bush, or Sultan Tunku Salahuddin. The same system of capitalization is
extended to the names of leaders with surnames that are not commonly
used such as Queen ELIZABE
