interpolate_pw()function; and correct geometry usage for PUMA geography in the 2021 ACS.
get_pums()now default to
year = 2020to retrieve data from the 2016-2020 5-year ACS. 2020 1-year data are not available in tidycensus and the package throws an error message; users should hard-code a different year to get 1-year ACS data.
as_dot_density()function allows users to quickly generate dots from data for dot-density mapping. This function requires the terra package to be installed.
interpolate_pw()function supports population-weighted interpolation of data between incongruent geometries, based on Esri’s weighted block centroid apportionment algorithm. A common use-case will be interpolating pre-2020 data to 2020 geometries like Census tracts and block groups.
get_pums()now correctly returns vacant housing units either when the
VACSvariable is requested or when
return_vacant = TRUE.
get_acs()now supports the ACS Comparison Profile data, helping users perform longitudinal demographic analyses correctly.
load_variables()now returns a
geographycolumn for the 5-year ACS Detailed Tables that tells users the smallest geography at which any given variable is available.
year = 2020in a call to
get_decennial()to access the data, and
load_variables(2020, "pl")to look up variable IDs.
"voting district"is now available for 2020 to assist with redistricting analyses.
get_flows(). Browse the supporting documentation for information on how to analyze and map migration flows data in tidycensus.
shift_geoargument is deprecated in favor of using the new
tigris::shift_geometry()function. This allows for shifting of geometries for any geography in national mapping projects.
get_pums(). Updated variable definitions are found in the data object
get_pums()is updated to 2019.
get_acs()now supports the
stateparameter for zip code tabulation areas (ZCTAs) to allow subsetting by state.
NEWS.mdfile to track changes to the package.
get_acs()now defaults to
year = 2019, meaning that 2015-2019 5-year estimates and 2019 1-year estimates are retrieved if no year is specified.
get_estimates()now also defaults to
year = 2019.
get_decennial()as the Census Bureau has restored its API endpoint.
geometry = TRUEnow works for all geographies currently available in tidycensus.
get_acs()can now support the ACS Supplemental Estimates API.
get_acs()now defaults to the 2014-2018 five-year American Community Survey estimates, or the 2018 1-year estimates if users set
survey = "acs1".
tidycensus now includes support for the Census Bureau Population Estimates API. Please see https://walkerke.github.io/tidycensus/articles/other-datasets.html for examples of how to use these new features.
Important internal changes to ensure that tidycensus continues to work with upcoming changes to Census API endpoints.
Several internal improvements and bug fixes. Please see the closed issues at https://github.com/walkerke/tidycensus/issues for a list.
Bug fixed that was causing GEOIDs for some states to be converted to NA on certain Linux platforms
A new parameter,
shift_geo, allows tidycensus users to get US state and county geometry originally obtained with the albersusa R package with Alaska and Hawaii shifted and re-scaled for better cartographic display of the entire US.
library(tidycensus) library(tidyverse) library(viridis) us_county_income <- get_acs(geography = "county", variables = "B19013_001", shift_geo = TRUE, geometry = TRUE) ggplot(us_county_income) + geom_sf(aes(fill = estimate), color = NA) + coord_sf(datum = NA) + theme_minimal() + scale_fill_viridis_c()
