DH Tools Series: Population Maps and Time-Series in R

This talk introduces the basics of creating choropleth maps (a type of thematic map in which areas are shaded in proportion to a statistical variable) of population data using R software. A basic suite of methods is applied to creating population maps based on census and survey data using units such as counties and census tracts. The talk will cover the essentials of data organization for joining population data to geospatial data, some basic principles of geospatial data in R, color schemes for maps in the ggplot R package, and procedure for writing code loops to create time-series maps and choropleths comparing different population attributes.
