These estimates were made for the DATASUS from the Brazilian Ministry of Health by the CGI Demográfico/RIPSA e CGIAE/SVSA/Ministério da Saúde.
I gather the brute data available at the datasus ftp [ftp://ftp.datasus.gov.br/dissemin/publicos/IBGE/POPSVS/], also available at TABNET.
The long file popBR2000-2025.long.csv contains the population for each municipality (with name and IBGE 6-digit code) by year.
The columns are
MUNCOD- Municipality IBGE 6-digit codeMUN- Municicipality nameAno- Year of the estimatePOP- Estimated population. For years 2000, 2010 and 2022 data came from IBGE census.
This code allows you to download the file directly from my github:
pop.git <- read.csv("https://raw.githubusercontent.com/lsbastos/popBR_mun/refs/heads/master/popBR2000-2025.long.csv")
All brute files are available at the folder brute/.
