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.
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.
