censobr: Download Data from Brazil’s Population Census

{censobr} is an R package to download data from Brazil’s Population Census. It provides a very simple and efficient way to download and read the data sets and documentation of all the population censuses taken in and after 1960 in the country. The package is built on top of the Arrow platform, which allows users to work with larger-than-memory census data using {dplyr} familiar functions.

Installation

# install from CRAN
install.packages("censobr")

# or use the development version with latest features
utils::remove.packages('censobr')
remotes::install_github("ipeaGIT/censobr", ref="dev")
library(censobr)

Basic usage

The package currently includes 6 main functions to download & read census data:

read_population()
read_households()
read_mortality()
read_families()
read_emigration()
read_tracts()

{censobr} also includes a few support functions to help users navigate the documentation Brazilian censuses, providing convenient information on data variables and methodology:

data_dictionary()
questionnaire()
interview_manual()

Finally, the package includes two functions to help users manage the data chached locally.

censobr_cache()
set_censobr_cache_dir()

The syntax of all {censobr} functions to read data operate on the same logic so it becomes intuitive to download any data set using a single line of code. Like this:

read_households(
  year,          # year of reference
  columns,       # select columns to read
  add_labels,    # add labels to categorical variables
  as_data_frame, # return an Arrow DataSet or a data.frame
  showProgress,  # show download progress bar
  cache          # cache data for faster access later
  )

Note: all data sets in {censobr} are enriched with geography columns following the name standards of the {geobr} package to help data manipulation and integration with spatial data from {geobr}. The added columns are: c(‘code_muni’, ‘code_state’, ‘abbrev_state’, ‘name_state’, ‘code_region’, ‘name_region’, ‘code_weighting’).

Data cache

The first time the user runs a function, {censobr} will download the file and store it locally. This way, the data only needs to be downloaded once. When the cache parameter is set to TRUE (Default), the function will read the cached data, which is much faster.

censobr_cache(): can be used to list and/or delete data files cached locally
set_censobr_cache_dir(): can be used to set custom cache directory for {censobr} files

Larger-than-memory Data

Microdata of Brazilian census are often be too big to load in users’ RAM memory. To avoid this problem, {censobr} will by default return an Arrow table, which can be analyzed like a regular data.frame using the dplyr package without loading the full data to memory.

More info in the package vignette.

Contributing to censobr

If you would like to contribute to {censobr}, you’re welcome to open an issue to explain the proposed a contribution.

As far as we know, {censobr} is the only R package that provides fast and convenient access to the complete data sets and documentation of Brazilian censuses. The microdadosBrasil package used to provide access to microdata of several public data sets, but unfortunately, it has been discontinued.
