Download spatial data of census tracts of the Brazilian Population Census
read_census_tract(
code_tract,
year = 2010,
zone = "urban",
simplified = TRUE,
showProgress = TRUE,
cache = TRUE
)
The 7-digit code of a Municipality. If the two-digit code
or a two-letter uppercase abbreviation of a state is passed, (e.g. 33
or "RJ") the function will load all census tracts of that state. If
code_tract="all"
, the function downloads all census tracts of the
country.
Numeric. Year of the data in YYYY format. Defaults to 2010
.
For census tracts before 2010, 'urban' and 'rural' census tracts are separate data sets.
Logic FALSE
or TRUE
, indicating whether the function
should return the data set with 'original' spatial resolution or a data set
with 'simplified' geometry. Defaults to TRUE
. For spatial analysis and
statistics users should set simplified = FALSE
. Borders have been
simplified by removing vertices of borders using st_simplify{sf}
preserving
topology with a dTolerance
of 100.
Logical. Defaults to TRUE
display progress bar.
Logical. Whether the function should read the data cached
locally, which is faster. Defaults to cache = TRUE
. By default,
geobr
stores data files in a temporary directory that exists only
within each R session. If cache = FALSE
, the function will download
the data again and overwrite the local file.
