A comparison of Parkes radio surveys and the X-ray ROSAT All-Sky Survey of the LMC has found 71 discrete sources of both radio and X-ray emission. These 71 sources are mainly supernova remnants (SNRs) and SNR candidates (36) and background sources (27). For six of the sources we have no clear identifications. A comparison of the radio and X-ray flux densities of all 71 sources shows very little correlation, but we note that the strongest SNRs at both radio and X-ray frequencies are young SNRs from Population I. Six new SNR candidates are proposed. From the brightness of the SNRs we estimate the SNR birth rate to be one every (100+/-20) years and the star formation rate to be (0.7+/-0.2) M_☉ yr(-1) .
