Summary: | Small area poverty maps allow for the
design of policies based on spatial differences in welfare.
They are typically estimated based on a consumption survey
reporting on poverty and a census providing the spatial
disaggregation. This paper presents a new method which
allows for the estimation of up-to-date small area poverty
maps when only a dated census and a more recent survey are
available and predictors and structural parameters are
subject to drift over time, a situation commonly encountered
in practice. Instead of using survey variables to explain
consumption in the survey, the new approach uses variables
constructed from the census. The proposed estimator has
fewer data requirements and weaker assumptions than common
small area poverty map estimators. Applications to simulated
data and to poverty estimation in Brazil show an overall
good performance. |
