Overview

World Population Prospects (WPP), the United Nations population estimates and projections prepared by DESA鈥檚 Population Division since 1951, form a comprehensive set of demographic data to assess population trends at the global, regional and national levels. Widely considered to be the world鈥檚 most authoritative dataset on population levels, trends and characteristics, WPP is used for calculating one-third of the indicators used to track progress towards the achievement of the Sustainable Development Goals (SDGs). Starting in 2021, WPP will estimate and project the population by single age for each year (鈥�1x1鈥�), replacing the current 鈥�5x5鈥� approach.

In order to achieve this objective, the Population Division is organizing an online expert group meeting on 鈥淢ethods for the World Population Prospects 2021 and beyond鈥� from 6 and 8 April 2020. The purpose of the meeting is to bring together experts to discuss and share experiences in the use of methods to develop robust annual time series of various demographic indicators (child, adult and old-age mortality, fertility, migration), incorporate uncertainty in population estimates, produce models to derive mortality and fertility age patterns, and reconcile the various demographic components of change to reconstruct coherent populations by age, period and cohort from 1950 to 2020.
