Abstract
AbstractSmall area estimation (SAE), which combines a population census and a sample survey, is widely used to estimate poverty and welfare indicators in small areas. A common situation in practice is that a population census is conducted using both short‐ and long‐form questionnaires. The short form is used to collect basic demographic information for the whole population, while the long form is used to collect additional information, such as employment, from a random sample. This study shows that combining both short‐ and long‐form data can improve estimation efficiency. This method is applied to poverty maps for the 2014–2019 period in Vietnam.
