tfr {wpp2012} | R Documentation |
Datasets containing the United Nations time series of the total fertility rate (TFR) for all countries of the world as available in 2012. Dataset tfr
contains estimates of the historical TFR starting with 1950; tfr_supplemental
contains a subset of countries for which data prior 1950 are available. Datasets tfrprojMed
contain the median projections. Datasets tfrproj80l
, tfrproj80u
, tfrproj95l
, and tfrproj95u
are the lower (l) and upper (u) bounds of the 80 and 95% probability intervals, respectively.
Datasets tfrprojHigh
and tfrprojLow
contain high and low variants, respectively, defined as +-1/2 child.

The datasets contain one record per country or region. It contains the following variables:
country
Name of country or region (following ISO 3166 official short names in English - see http://www.iso.org/iso/country_codes/iso_3166_code_lists/english_country_names_and_code_elements.htm and United Nations Multilingual Terminology Database - see http://unterm.un.org).

1950-1955
, 1955-1960
, ...TFR in various five-year time intervals. last.observed
containing the year of the last observation for each country. The tfrproj*
datasets start at 2010-2015
. The tfr_supplemental
datasets start at 1740-1745
. Missing data have NA
values.
These datasets are based on estimates and projections of United Nations, Department of Economic and Social Affairs, Population Division (2013).
