Source: R/us_pop_multirace_adjusted_in_btm_codes_by_region.R
us_pop_multirace_in_nmdp_codes_by_region.Rd

This function retrieves and processes US Census 2020 population data to calculate population numbers by NMDP (National Marrow Donor Program) race codes and by region. It supports filtering by state or county and adjusts for individuals reporting multiple races.

Usage

us_pop_multirace_in_nmdp_codes_by_region(
  in_region,
  census_region_level = "state"
)

Arguments

in_region

A string specifying the region of interest. Valid values are:

  • "us" - Entire United States

  • "all states" - All states (not recommended for use)

  • "all counties" - All counties

  • A valid state name (e.g., "Alaska")

census_region_level

A string specifying the granularity of the data:

  • "state" - Data divided by state (default)

  • "county" - Data divided by county within a state

Value

A data frame containing population numbers by NMDP race codes and region, with the following columns:

  • region - The specified region (e.g., state or county)

  • nmdp_race_code - NMDP race code

  • total_single_race_pop - Population reporting a single race

  • total_multiple_race_pop - Population reporting multiple races

  • total_2020_pop - Total population (single + multiple race)

  • census_region - Census region corresponding to the input region
