Query: The stellar population of bulges   This review summarizes the properties of the stellar population in bulges as
observed in nearby or distant spiral galaxies. It gives a particular emphasis
to the comparison with elliptical galaxies, when possible. The criteria of
sample selection and choices in data analysis are addressed when they may be
involved in discrepant results reached by different studies.
