Prevalencemaps is an online R Shiny application for visualizing and exploring prevalence data for multiple conditions as collected by the Selected Metropolitan/Micropolitan Area Risk Trends (SMART) and Behavioral Risk Factor Surveillance System (BRFSS) survey for U.S Metropolitan and Micropolitan Statistical Areas (MMSAs) from the years of 2011 to 2017

Prevalencemaps is a user-friendly resource for the exploration of relationships among BRFSS variables, including geospatial trends at the level of MMSAs. Data displayed in the maps and MMSA-specific graphs were weighted using survey weights from the BRFSS source data and created with the R rgeos, rgdal, and sf packages. Along with displaying the geographical distribution of various BRFSS health outcomes and demographic factors, the app also provides bivariate and multivariable relationship graphics.
Prevalencemaps was created using RStudio's Shiny. Running the app locally requires R, with the following packages installed: shiny, leaflet, shinyWidgets, ggplot2, shinydashboard, tigris, dplyr, reshape2, rgdal, rgeos, sf, feather, survey, jtools, sjPlot, bbplot
