Datasets that start with popM or popF and do not have “T” in their names, are age-specific and are organized as data frames with one row per country and age group. For each country there are 21 age groups. It contains the following variables:

country_code: Numerical Location Code (3-digit codes following ISO 3166-1 numeric standard) - see http://en.wikipedia.org/wiki/ISO_3166-1_numeric.
name: Country name.
age: A character string representing an age interval. For each country there are 21 values: “0-4”, “5-9”, “10-14”, “15-19”, “20-24”, “25-29”, “30-34”, “35-39”, “40-44”, “45-49”, “50-54”, “55-59”, “60-64”, “65-69”, “70-74”, “75-79”, “80-84”, “85-89”, “90-94”, “95-99”, and “100+” in that order. If there are NAs for ages 85 and older, the “80-84” category is to be treated as “80+”.
1950, 1955, ...: Population estimate or projection (in thousand) for the given time (mid-year).

The remaining datasets, i.e. those that do not have “M” or “F”, or have “T” in their names, contain one row per country.

Dataset pop provides estimates of historical total population counts.

Datasets popMT and popFT provide estimates of total counts of male and female population, respectively.

Datasets popM (popF) contain age-specific estimates of the historical population counts for male (female).

Dataset popproj provides median projection of total population counts, i.e. aggregated over sex and age. Datasets popproj80l, popproj80u, popproj95l, and popproj95u are the lower (l) and upper (u) bounds of the 80 and 95% probability intervals of the total population. Datasets popprojHigh and popprojLow contain the upper and lower variant of total population defined as +- 1/2 child.

Datasets popMTproj and popFTproj provide median projection of total counts of male and female population, respectively.

Datasets popXprojMed, popXprojHigh and popXprojLow contain median, high and low variants of age-specific projections, respectively, with X=M for male and X=F for female.

All values are in thousands.

These datasets are based on estimates and projections of United Nations, Department of Economic and Social Affairs, Population Division (2017).
