Abstract We update the systematic studies of circular polarization in integrated pulse profiles of Han et al. Sense reversal can occur in either core or cone components, or near the intersection between the components. The correlation between the sense of circular polarization and the sense of position angle variation for conal double pulsars is confirmed with a much larger database. Some pulsars show clear changes of circular polarization with frequency. Circular polarization is marginally different between millisecond and normal pulsars.
