The NIDS weights were derived in two stages. In the first, the design weights were calculated as the inverse of the inclusion probability. In the second, the weights were calibrated to the 2008 midyear estimates. In practice the process was a bit more complicated so there are not just two sets of weights available. In this document we set out how the weights were calculated and what choices were necessary in the process.
