Based on Einstein IPC data, we have completed a census of X-ray emission from and around OB associations in the LMC. In addition to an apparent correlation of young, X-ray bright supernova remnants with recent star formation regions, we detect diffuse X-ray emission from over two dozen other associations; luminosities in the 0.16–3.5 keV band range from ˜ 3 × 1034 (the detection threshold) to ˜ 1036erg s−1. The mean X-ray luminosity of the ˜ 50 undetected associations is ˜ 1034erg s−1 and the emission from all associations contributes ˜ 4% to the total diffuse X-ray emission from the galaxy. Implications of this survey for ISM bubble evolution is discussed.
