This article argues that precise measurement is often inappropriate in relation to complex, multidimensional issues such as poverty. A good indicator should be understood as a pointer, not a measure. It should be accessible, robust and reinforced by other pointers. By treating indicators as quantities, summary indices conceal key issues, hide the values and concepts implicit in the exercise, and are vulnerable to mathematical accident. Using multiple indicators is sounder in principle, in methodological terms, and in practical application
