Format

Datasets that start with popM, popF, popPropM or popPropF 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

Country name.

country_code

Numerical Location Code (3-digit codes following ISO 3166-1 numeric standard) - see http://en.wikipedia.org/wiki/ISO_3166-1_numeric.

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.

1950, 1955, ...

Population estimate or projection (in thousand) for the given time (mid-year).

The remaining datasets, i.e. those that either do not have “M” and “F” in their names or that start with popTM and popTF, contain one row per country.

Details

Dataset pop provides estimates of historical total population counts.

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

The remaining datasets contain projections. Their suffix determines if it is a median (“Med” or “”), half a child variant (“Low”, “High”), or lower (“l”) or upper (“u”) bound of the 80 and 95% probability interval.

Dataset popproj provides median projection of total population counts, i.e. aggregated over sex and age. All datasets that start with “popproj” refer to total population.

Datasets that start with “popTMproj” and “popTFproj” contain projections of population for male and female, respectively, summed over ages.

Datasets that start with “popMproj” and “popFproj” age-specific projections for male and female, respectively.

Datasets that start with “popPropM” and “popPropF” contain sex- and age-specific projections on the scale of proportions.

All values are in thousands.

Source

Projections were produced using the Azose et al. (2016) methodology. Historical estimates were provided by the United Nations, Department of Economic and Social Affairs, Population Division (2015).
