\abstract{
Using a population synthesis code, we calculate the expected
nova rate in stellar systems with different star formation
histories, for a variety of input parameters concerning the
initial binary population. We show that the current nova rate
in galaxies is determined by their star formation history. We
show that in irregular and spiral galaxies, the currently observed
nova rates are determined mainly by the present disk star
formation rate, while in elliptical galaxies it depends mainly
on the mass of the galaxy. This offers an explanation for the
suspected differences in the observed nova rates per unit of
$K$~luminosity in different galaxies. The differences between bulge
and disk novae in the Galaxy are probably also related to the
respective ages of the parent populations.}
