The turnover of the membership of a legislative body is described by the exponential probability distribution, where observations are made after successive elections following some starting point. The application of this model, including the estimation of the decay constant for particular cases, is illustrated by examples drawn from five countries. Students compute estimates of decay constants and draw substantive conclusions about attrition processes.
