What is it about?
We often use indices combining many indicators in the social sciences. We can increase the (construct) validity of our research by recombining individual indicators of existing indices. I demonstrate this using indicators from the Migration Integration Policy Index (MIPEX) to approximate Koopmans et al.'s conception of citizenship models. The recombined MIPEX data match the data by Koopmans et al., but by re-using the MIPEX we immediately get wider coverage.

Why is it important?
Because collecting data for an index is often beyond what a research project can afford, we often rely on existing indices -- at a cost of (construct) validity. By recombining the individual indicators, we can often create a custom index closer to what we want to do.
