bg22DemographicSubgroups2016to2020: Demographic subgroups of race/ethnicity by block group

In ejanalysis/ejscreen: EJScreen Tools for US EPA Environmental Justice (EJ) Mapping and Screening

Demographic subgroups of race/ethnicity by block group

Description

bg22DemographicSubgroups provides subgroups that are the ones making up EJScreen's such as Hispanic or Latino, Non-Hispanic Black Alone, etc.

Details

  This dataset is a companion to the block group data from EJScreen.
  EJScreen and therefore bg22 would have lacked table B03002 (race ethnicity)
   so that table is obtained as bg22DemographicSubgroups

 This also includes race/ethnicity data for Puerto Rico, but not GU/AS/VI/MP.

   EJScreen 2.1 uses ACS2020, which is from 2016-2020 
   (released March 17 2022, delayed from Dec 2021).
   It was to be called the 2022 version of EJScreen, and
   here is called bg22.

 EJScreen 2.0 was released by EPA 2022-02-18 (delayed from mid/late 2021).
   EJScreen 2.0 used ACS2019, which is from 2015-2019 (released Dec 2020).
   It was to be a late 2021 version, and here had been called bg21.
   
  bg22DemographicSubgroups was created by downloading and calculating
  RACE ETHNICITY SUBGROUP VARIABLES THAT ARE NOT IN EJSCREEN
  (the subgroups within "minority" or "people of color").
  This is from Census Table B03002, and includes percent Hispanic,
  percent Non-Hispanic Black Alone (not multirace), etc.
  Race ethnicity groups are defined by Census Bureau. They are
  mutually exclusive (no overlaps between groups,
  so a person is always in only one of these groups)
  so they add up to the total population count or percent.
  Block group resolution for USA.
  From Census ACS 5 year summary file.
  
  This will give a quick look at some key stats: 
    # round(data.frame(cbind( 
    # subgroups=unlist(ustotals(bg22DemographicSubgroups2016to2020)),
    # maingroups = unlist(ustotals(subset(bg22, bg22$ST !='PR')))  
    # ),2)

    # see  ejscreen/inst/SCRIPT_create_bgDemog_ejscreen2.1_andtracts.R
    # the SCRIPT for how this was created
    # and  ejscreen/inst/SCRIPT_ADD_PUERTORICO_DEMOG_SUBGROUPS.R for PR part.

    # DOWNLOADED ACS TABLE WITH RACE ETHNICITY BY BLOCK GROUP
    # AND CREATE PERCENT VARIABLES LIKE PERCENT HISPANIC, ETC.

  # These are created: (count and percent hispanic or latino, 
   # nonhispanic white alone i.e. single race,
  # nonhispanic black or african american alone, Not Hispanic or Latino 
  #   American Indian and Alaska Native alone,
  # Not Hispanic or Latino Native Hawaiian and Other Pacific Islander alone,
  # and nh some other race alone, and nh two or more races):

  # "hisp"          "nhwa"      "nhba"       "nhaiana"  "nhaa"  "nhnhpia"
  # "nhotheralone"  "nhmulti"   "nonmins"    "pcthisp"  "pctnhwa" "pctnhba"
  # "pctnhaiana"    "pctnhaa"   "pctnhnhpia" "pctnhotheralone" "pctnhmulti"
