This paper first examines the frequency of direct presidential electio
ns among the 170 countries of the world with a working, directly elect
ed parliament. We find that there is a directly elected president in m
ore than half of the countries and in about two-thirds of the republic
s. Former British colonies are less likely to hold direct presidential
elections, which are otherwise very popular in North and South Americ
a and Africa. We then examine the kind of electoral formula that is us
ed for the election of presidents. Most elections are held under the m
ajority rule, most of the time under the majority runoff procedure. Th
e majority rule is clearly predominant in Europe and Africa, and is un
popular in North America, Finally, no relationship is observed between
the level of economic development or of democracy and the use of dire
ct presidential elections or the choice of an electoral formula. (C) 1
