Workshop on population estimates and projections for Namibia

Okahandja, Namibia

05 August 2019 to 09 August 2019

Overview

Technical staff from the Namibia Statistics Agency, government line ministries (Planning, Education, Health, and Immigration), and researchers from higher education institutions were trained in methods for assessing the quality of demographic statistics, projecting the national population, and projecting sub-national (regional) populations.
