Download census tract-level aggregate data from Brazil's censuses.

Usage

read_tracts(
  year,
  dataset,
  as_data_frame = FALSE,
  showProgress = TRUE,
  cache = TRUE,
  verbose = TRUE
)

Arguments

year

Numeric. Year of reference in the format yyyy.

dataset

Character. The dataset to be opened. The following options are available for each edition of the census:

2000 Census

  • c("Basico", "Domicilio", "Responsavel", "Pessoa", "Instrucao", "Morador").

2010 Census

  • c("Basico", "Domicilio", "DomicilioRenda", "Responsavel", "ResponsavelRenda", "Pessoa", "PessoaRenda", "Entorno").

2022 Census

  • c("Basico", "Domicilio", "ResponsavelRenda", "Pessoas", "Indigenas", "Quilombolas", "Entorno", "Obitos", "Preliminares").

The censobr package exposes all original IBGE census tracts datasets, regrouping them into broader themes and appending geographic identifiers so that they align seamlessly with geobr shapefiles.

For a complete description of the datasets, themes, and variables, check

  • data_dictionary(year = 2000, dataset = "tracts"),

  • data_dictionary(year = 2010, dataset = "tracts"),

  • data_dictionary(year = 2022, dataset = "tracts").

as_data_frame

Logical. When FALSE (Default), the function returns an Arrow Dataset, which allows users to work with larger-than-memory data. If TRUE, the function returns data.frame.

showProgress

Logical. Defaults to TRUE display download progress bar. The progress bar only reflects only the downloading time, not the time to load the data to memory.

cache

Logical. Whether the function should read the data cached locally, which is much faster. Defaults to TRUE. The first time the user runs the function, censobr will download the file and store it locally so that the file only needs to be download once. If FALSE, the function will download the data again and overwrite the local file.

verbose

A logical. Whether the function should print informative messages. Defaults to TRUE.

Value

An arrow Dataset or a "data.frame" object.

Examples

library(censobr)

# return data as arrow Dataset
df <- read_tracts(
  year = 2022,
  dataset = 'Domicilio',
  showProgress = FALSE
  )
#> ℹ Downloading data and storing it locally for future use.

# return data as data.frame
df <- read_tracts(
  year = 2010,
  dataset = 'Basico',
  as_data_frame = TRUE,
  showProgress = FALSE
  )
#> ℹ Downloading data and storing it locally for future use.
