Low-income countries are also often data poor, lacking recent cen- suses or surveys to inform policy and programs. Without a recent national population census, countries do not know how to sam- ple for nationally-representative surveys. This brief discusses how countries can generate nationally-representative surveys without a recent census by relying on publicly available high resolution ge- ospatial data. The brief discusses how such geospatial data and sampling were used to create the Sudan Labor Market Panel Sur- vey (SLMPS) 2022. Sudan’s last population census was in 2008, a number of years ago, and before the country was divided. The SLMPS is Sudan’s first nationally representative household survey since 2014 and first labor force survey since 2011. These methods can be used in other contexts that lack a recent official census or for sampling between censuses in areas with substanial changes in population.
