\format{
  The datasets contain one record per country or region. They contain the following variables:
  \describe{
    \item{\code{country}}{Name of country or region (following ISO 3166 official short names in English - see \url{https://www.iso.org/obp/ui/#search/code/} and United Nations Multilingual Terminology Database - see \url{https://unterm.un.org/unterm2/}).}
    \item{\code{country_code}}{Numerical Location Code (3-digit codes following ISO 3166-1 numeric standard) - see \url{https://en.wikipedia.org/wiki/ISO_3166-1_numeric}.}
    \item{\code{1950-1955}, \code{1955-1960}, \dots}{Life expectancy in various five-year time intervals (i.e., from 1 July in year t to 1 July in year t+5 such as the period 1950-1955 refers to the period 1950.5-1955.5 and the mid of the period is 1953.0). \code{last.observed} containing the year of the last observation for each country. The \code{e0*proj} datasets start at \code{2015-2020}. The \code{e0*_supplemental} datasets start at \code{1750-1755}. Missing data have \code{NA} values.}

\details{
	Datasets \code{e0F} and \code{e0F_supplemental} contain estimates for female historical e0; \code{e0M} and \code{e0M_supplemental} contain estimates for male historical e0. The \code{*_supplemental} datasets contain a subset of countries for which data prior 1950 are available. Datasets \code{e0Mproj} and \code{e0Fproj} contain projections of male and female e0, respectively. Datasets \code{*80l}, \code{*95l} are the lower bounds of 80 and 95\% probability intervals,  \code{*80u}, \code{*95u} are the corresponding upper bounds.

The historical dataset (e0F_supplemental.txt and e0M_supplemental.txt for female and male respectively) for 29 countries or areas covers the period 1750-1950 (including 20 countries with data since at least 1900) is based on a series for 5-year periods from the following sources: (1) University of California at Berkeley (USA), and Max Planck Institute for Demographic Research (Germany).
