Download ACS tables EJSCREEN uses, but with more race ethnicity poverty details

Description

EJScreen 2.0 was latest as of June 2022, released early 2022, and actually used ACS2019, which is from 2015-2019 (released late 2020).

Helper function used by ejscreen.create, but can be used if one wants to obtain the more detailed relevant ACS data. The EJSCREEN-related ACS tables have more of the detailed fields than the demographic data on the EJSCREEN FTP site, because the detailed fields are used to calculate the ones retained for EJSCREEN, such as percent non-hispanic black alone, percent hispanic, percent poor (<1x poverty line) not just percent low income (<2x poverty line), etc.

Usage

ejscreen.acsget(
  end.year = "2020",
  tables = c("B01001", "B03002", "B15002", "C16002", "C17002", "B25034", "B23025"),
  base.path = getwd(),
  data.path = file.path(base.path, "acsdata"),
  output.path = file.path(base.path, "acsoutput"),
  vars = "all",
  sumlevel = "bg",
  write.files = TRUE,
  ...
)

Arguments

end.year	optional character year like 2020 specifying last of 5 years of ACS summary file
tables	Default is the ones needed for EJSCREEN - character vector list of Census data tables like B01001
base.path	optional, default is working directory; folder in which data.path and output.path subfolders are or will be created
data.path	see ACSdownload::get.acs()
output.path	see ACSdownload::get.acs()
vars	Default here is 'all' vars which is more than what ejscreen.create keeps. (or can be a vector of things like 'B01001')
sumlevel	Default here is just bg but see ACSdownload::get.acs()
write.files	Default here is TRUE but see ACSdownload::get.acs()
