In order to assess quality, empirical basis and uncertainty of estimates of life expectancy at birth (LEB) for all countries in the world, we collected, organized, and documented all available external data on life expectancy at birth. In this report we present trends in life expectancy at birth produced in the 2017 revision of World Population Prospects (WPP) together with data from external sources. We discuss availability, timeliness, and possible explanations for the differences between UNPD estimates and the data from external sources, for selected countries.
