Obtain data and feature geometry for the decennial Census
get_decennial(geography, variables, year = 2010, sumfile = "sf1",
state = NULL, county = NULL, geometry = FALSE, output = "tidy",
keep_geo_vars = FALSE, summary_var = NULL, key = NULL, ...)The geography of your data.
Character string or vector of character strings of variable IDs.#'
The year for which you are requesting data. 1990, 2000, and 2010 are available.
The Census summary file. Defaults to sf1; the function will look in sf3 if it cannot find a variable in sf1.
The state for which you are requesting data. State names, postal codes, and FIPS codes are accepted. Defaults to NULL.
The county for which you are requesting data. County names and FIPS codes are accepted. Must be combined with a value supplied to `state`. Defaults to NULL.
if FALSE (the default), return a regular tibble of ACS data. if TRUE, uses the tigris package to return an sf tibble with simple feature geometry in the `geometry` column. state, county, tract, and block group are supported for 1990 through 2010; block and ZCTA geometry are supported for 2000 and 2010.
One of "tidy" (the default) in which each row represents an enumeration unit-variable combination, or "wide" in which each row represents an enumeration unit and the variables are in the columns.
if TRUE, keeps all the variables from the Census shapefile obtained by tigris. Defaults to FALSE.
Character string of a "summary variable" from the decennial Census to be included in your output. Usually a variable (e.g. total population) that you'll want to use as a denominator or comparison.
