In trulia/rUnemploymentData: Data and Functions for USA State and County Unemployment Data

US County Unemployment Data

Data

This package contains a data.frame called ?df_county_unemployment which contains unemployment data on US Counties from 2000-2014. The data is annualized, which means that there is one data point per County per year:

library(rUnemploymentData)

data(df_county_unemployment)
?df_county_unemployment

head(df_county_unemployment)

The data was scraped from the US Bureau of Labor Statistics (BLS) Local Area Unemployment Statistics (LAUS) webpage on January 4, 2014 (http://www.bls.gov/lau/) with the function ?build_county_df.

Visualization - Boxplot

The easiest way to visualize the entire dataset is with a boxplot.

?boxplot
boxplot(df_county_unemployment[, c(-1, -2, -3)],
        main="USA County Unemployment Data",
        xlab="Year",
        ylab="Percent Unemployment")

This visualization shows you, by year, the distribution of the unemployment rate in each county. For example, the recession that began in 2009 is very clear in this graph.

Visualization - Choropleth Map

This package also comes with a function to create choropleth maps of the data:

?county_unemployment_choropleth
county_unemployment_choropleth(year=2013)

Choropleth maps are useful for understanding the geographic distribution of values. For example, in this map it is clear that - with some notable exceptions - in 2013 the unemployment rate was very low in the central part of the US.

Visualization - Animated Choropleths

A third option for visualizing the data is with an animated choropleth map:

?animated_county_unemployment_choropleth
# animated_county_unemployment_choropleth()

This function is commented out in the above example because the resulting image cannot render inside a vignette. If you are interested in this visualization, then please type the command locally. Note that it will write files to your local file system - see ?choroplethr_animate in the choroplethr package for details.
