Discussions of the conventional income/consumption and participatory a
pproaches to poverty measurement have focused on the trade-off between
'objective' and subjective measures of poverty. The trade-offs betwee
n the identification and aggregation of the poor and between static an
d dynamic measurement have been neglected. Although, the income/consum
ption approach may sometimes misidentify the poor, its well understood
aggregation properties make it extremely useful for regional and nati
onal level policy making. In contrast, participatory methods are most
valuable for identifying the other, more subjective, dimensions of pov
erty at the project or village level. In order to be able to distingui
sh between chronic and transitory poverty, both approaches need to pay
more attention to dynamic issues and the ability to track the poverty
status of households and individuals over time.
