Publishing subnational estimates with confidence intervals is important for their correct interpretation and use. Despite the development of software routines for the computation of standard errors, users of household survey data with complex design can often only approximate the variance of their regional estimates. This is due to limited infomiation on the survey’s sampling structure in the microdata available to researchers. As discussed in detail in Annex 2, the provision of ‘computational strata and PSUs’ variables in the public-use files would improve the capacity of users to correctly estimate the sampling variance, with limited confidentiality issues.
