We present the results of a photometric survey for Be stars in 11 young clusters in the Large Magellanic Cloud and 14 young clusters in the Small Magellanic Cloud. B stars with hydrogen in emission are identified on the basis of their R−Hα colour. We find that Be star fraction in clusters decreases with cluster age and also decreases with the metallicity.
