In tidycensus: Load US Census Boundary and Attribute Data as 'tidyverse' and 'sf'-Ready Data Frames

tidycensus 1.5

• Support added for the new Detailed DHC-A file, which includes the ability to query for detailed population groups. This functionality is now enabled for Summary Files 2 and 4 in past years as well with the pop_group argument.
• Full geometry support enabled for the 2022 1-year American Community Survey.
• Various bug fixes and performance improvements, including the pesky 'Error in UseMethod("gather") no applicable method for 'gather' applied to an object of class "character"' problem.

tidycensus 1.4.4

• get_estimates() now supports the newer Population Estimates Program (PEP) datasets not found on the Census API. Please review the package documentation at https://walker-data.com/tidycensus/articles/other-datasets.html for examples of how to use the new datasets, which differ slightly from older versions.
• Decennial Census data for island areas and some historical decennial Census files (for 2000) are now available. To see a full list of decennial Census datasets available in tidycensus, use the summary_files() function.

tidycensus 1.4

• get_decennial() has been updated to accommodate the new Demographic and Housing Characteristics and Demographic Profile summary files. Use sumfile = "dhc" for the DHC file, and sumfile = "dp" for the DP file.
• The default year in get_decennial() is now 2020. This may be a breaking change for some legacy code that omits the year, so be sure to update scripts to hard-code the year for years earlier than 2020.
• sumfile = "pl" is the default for get_decennial() and will remain so to avoid existing code breakages. Please note that variable IDs are replicated across the PL and DHC files, but may represent different topics.

tidycensus 1.3

• Given that the Census API allows for 500 queries per day without an API key, the API key requirement in the package has been removed to support reproducibility. Users without a key are now warned of potential performance limitations.
• PUMS variables for 2021 have been added to the pums_variables data dictionary object.
• Various bug fixes and performance improvements; browse the GitHub issues for a complete listing.

tidycensus 1.2.3

• Minor release with bug fixes and performance improvements. Fixes include support for the 2000 SF3 Data Profile; improvements to the interpolate_pw() function; and correct geometry usage for PUMA geography in the 2021 ACS.

tidycensus 1.2

• get_acs() and get_pums() now default to year = 2020 to 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.
• A new 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.
• A new 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 VACS variable 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 geography column for the 5-year ACS Detailed Tables that tells users the smallest geography at which any given variable is available.
• Numerous bug fixes and performance improvements.

tidycensus 1.1

• tidycensus now supports the 2020 decennial Census PL-94171 redistricting data. Use year = 2020 in a call to get_decennial() to access the data, and load_variables(2020, "pl") to look up variable IDs.
• A new geography, "voting district" is now available for 2020 to assist with redistricting analyses.

tidycensus 1.0

• Support for the ACS Migration Flows API is available in a new function, get_flows(). Browse the supporting documentation for information on how to analyze and map migration flows data in tidycensus.
• The shift_geo argument 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.
• Various bug fixes and performance improvements; browse the GitHub issues for a complete listing.

tidycensus 0.11.4

• Added support for the 2015-2019 5-year ACS PUMS data in get_pums(). Updated variable definitions are found in the data object pums_variables.
• The default year in get_pums() is updated to 2019.
• For 2015-2019 ACS aggregate data, get_acs() now supports the state parameter for zip code tabulation areas (ZCTAs) to allow subsetting by state.
• Various bug fixes and internal improvements; browse the GitHub issues for a complete listing.
• Added a NEWS.md file to track changes to the package.

tidycensus 0.11

• 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.
• tidycensus can once again access the 2000 Summary File 3 in get_decennial() as the Census Bureau has restored its API endpoint.
• Various bug fixes and internal improvements; browse the GitHub issues for a complete listing.

tidycensus 0.10.2

• tidycensus now includes functionality to download and analyze data from the American Community Survey Public Use Microdata Series (PUMS) datasets. Read through the corresponding documentation to learn how to use these features.
• tidycensus cannot access 1990 data or 2000 Summary File 3 data due to the removal of these API endpoints by the Census Bureau. When new endpoints for these years are added, tidycensus will support them again in a future release.

tidycensus 0.9.9.2

• geometry = TRUE now works for all geographies currently available in tidycensus.
• get_acs() can now support the ACS Supplemental Estimates API.

tidycensus 0.9.5

• 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".
• Various improvements and bug fixes (largely thanks to Matt Herman's contributions).

tidycensus 0.8.1

• 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.

tidycensus 0.4.6

• 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.
