  Censuses are fundamental building blocks of most modern-day societies, yet
collected every ten years at best. We propose an extension of the widely
popular census updating technique Structure Preserving Estimation by
incorporating auxiliary information in order to take ongoing subnational
population shifts into account. We apply our method by incorporating satellite
imagery as additional source to derive annual small-area updates of
multidimensional poverty indicators from 2013 to 2020 for a population at risk:
female-headed households in Senegal. We evaluate the performance of our
proposal using data from two different census periods.
