findSVI

R-CMD-check

The goal of findSVI is to calculate regional CDC/ATSDR Social Vulnerability Index (SVI) at a geographic level of interest using US census data from American Community Survey.

Overview

CDC/ATSDR releases SVI biannually at the counties/census tracts level for US or an individual state (which can be downloaded here). findSVI aims to support more flexible and specific SVI analysis with additional options for years (2012-2021) and geographic levels (e.g., ZCTA/places, combining multiple states).

To find SVI for one or multiple year-state pair(s):

In most cases, find_svi() would be the easiest option. If you’d like to include simple feature geometry or have more customized requests for census data retrieval (e.g., different geography level for each year-state pair, multiple states for one year), you can process individual entry using the following:

Essentially, find_svi() is a wrapper function for get_census_data() and get_svi() that also supports iteration over 1-year-and-1-state pairs at the same geography level.

Installation

Install the findSVI package via CRAN:

install.packages("findSVI")

Alternatively, you can install the development version of findSVI from GitHub with:

# install.packages("devtools")
devtools::install_github("heli-xu/findSVI")

Usage

library(findSVI)
library(dplyr)

summarise_results <- find_svi(
  year = c(2017, 2018),
  state = c("NJ", "PA"),
  geography = "county"
)
summarise_results %>% 
  group_by(year, state) %>% 
  slice_head(n = 5)
