Surveys at a variety of wavelengths indicate that galaxy interactions are statistically linked to enhanced rates of star formation. The distributions of star-formation rate (SFR) show typical increases of order 30%, and only a few systems undergoing the order-of-magnitude enhancements typical of strong starbursts (particularly in mergers). Potential advantages and problems of various measures of SFR are discussed, along with issues of sample selection and comparison. Finally, various proposed mechanisms for enhancing the SFR during interactions are listed, with relevant observational tests. Current data suggest that several physical processes may contribute to star formation during interactions.
