United Nations Time Series of Total Fertility Rate

Description

Datasets containing the United Nations time series of the total fertility rate (TFR) for all countries of the world as available in 2019.

Usage

data(tfr)
data(tfr_supplemental)

data(tfrprojMed)
data(tfrproj80l)
data(tfrproj80u)

data(tfrproj95l)
data(tfrproj95u)

data(tfrprojHigh)
data(tfrprojLow)

Format

The datasets contain one record per country or region. 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

Name of country or region (following ISO 3166 official short names in English - see https://www.iso.org/obp/ui/#search/code/ and United Nations Multilingual Terminology Database - see https://unterm.un.org/unterm).

1950-1955, 1955-1960, ...

TFR 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). The tfrproj* datasets start at 2020-2025. The tfr_supplemental datasets start at 1740-1745. Missing data have NA values.

Details

Dataset tfr contains estimates of the historical TFR starting at 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 historical dataset tfr_supplemental (for 103 countries or areas) covers the period 1740-1950 (including 24 countries with data before 1850), and is based on series for five-year periods from the following sources: (1) Max Planck Institute for Demographic Research (Germany) and Vienna Institute of Demography (Austria).
