Data Sources

A description of the empirical data used and the methods applied in revising past estimates of population and components of demographic change (fertility, child, adult and overall mortality, international migration) is available here for each country or area for the period 1950-2020. For the countries with less than 90,000 inhabitants in 2019, only the data sources for total population are made available.

Central African Republic
Population: Total population and distribution by age and sex estimated to be consistent with the population by age and sex of the (a) 1959-1960 Survey and 1975, 1988, 2003 censuses; (b) adjusted censuses for underenumeration; and with estimates of the subsequent trends in fertility, mortality and international migration.

Fertility: Total fertility rate and age pattern of fertility based on: (a) birth-histories data from the 1994-1995 DHS; (b) births in the household in the preceding 12 (or 24) months classified by age of mother from the 1959-1960 Survey and 1975, 1988, 2003 censuses and 2000, 2006, 2010 MICS; (c) adjusted fertility using Brass P/F ratio method (or variants) with data on children ever born and births in the preceding 12 (or 24/36) months, both classified by age of mother, from the 1975, 1988, 2003 censuses; (d) cohort-completed fertility backdated by the mean age of childbearing from the 1994-1995 DHS and 2003 Census.  In addition, the cohort-completed fertility backdated by the mean age of childbearing from the 1975, 1988 censuses and 2006, 2010 MICS have been considered.

Child Mortality: Under-five mortality based on: (a) direct estimates from births and deaths under-five calculated from full birth histories data from the 1994-1995 DHS; (b) indirect estimates from data on children ever born and surviving from the 1975, 1988, 2003 censuses and 2000, 2006, 2010 MICS; (c) recent household deaths from the 1959-1960 Survey and 1988, 2003 censuses; (d) International estimates used up to 2018.

Overall Mortality: Life expectancy at birth and age pattern of mortality based on: (a) International estimates considered up to 2017; (b) The demographic impact of AIDS has been factored into the mortality estimates; (c) estimates using HIV/AIDS model life tables and estimates of under-five mortality (5q0), and adult mortality (45q15).  In addition, the official estimates through 2007 have been considered.

Adult and Old Age Mortality: Estimates derived from: (a) recent household deaths data by age and sex from the 1988, 2003 censuses; (b) recent household deaths adjusted at adult ages for underregistration using death distribution methods; (c) siblings deaths from the 1994-1995 DHS; (d) maternal orphanhood from the 1988, 2003 censuses and 1994-1995 DHS; (e) paternal orphanhood from the 1988, 2003 censuses and 1994-1995 DHS; (f) intercensal survivorship from successive census age distributions; (g) International estimates considered up to 2017.

Migration: International migration based on: (a) information on foreign-born populations from censuses and registers from major countries of destination; (b) estimates derived as the differences between overall population growth and natural increase; (c) UNHCR statistics on the number of refugees in the main countries of asylum.
