In nmmarquez/censeg: Calculate Segregation Measures from Census Data

Description

get_decennial_metro uses the census api to download data for all 50 states plus DC for "on spine" geographies county and below. This method will associate those geographies with a CBSA as well.

Usage

get_decennial_metro(
  geography,
  variables = NULL,
  table = NULL,
  cache_table = FALSE,
  year = 2010,
  sumfile = "sf1",
  output = "tidy",
  summary_var = NULL,
  key = NULL,
  show_call = FALSE,
  ...
)

Arguments

geography	unit for which to pull data
variables	Character string or vector of character strings of variable IDs.
table	The Census table for which you would like to request all variables. Uses lookup tables to identify the variables; performs faster when variable table already exists through load_variables(cache = TRUE). Only one table may be requested per call.
cache_table	Whether or not to cache table names for faster future access. Defaults to FALSE; if TRUE, only needs to be called once per dataset. If variables dataset is already cached via the load_variables function, this can be bypassed.
year	The year for which you are requesting data. 1990, 2000, and 2010 are available.
sumfile	The Census summary file. Defaults to sf1; the function will look in sf3 if it cannot find a variable in sf1.
output	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.
summary_var	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.
key	Your Census API key. Obtain one at http://api.census.gov/data/key_signup.html
show_call	if TRUE, display call made to Census API. This can be very useful in debugging and determining if error messages returned are due to tidycensus or the Census API. Copy to the API call into a browser and see what is returned by the API directly. Defaults to FALSE.
...	Other argumenets to pass to get_decennial.

Value

data frame with census info and adjoined cbsa location
