We have already seen this semester that the cost of housing in the United States has been rising for several decades. A household is considered cost-burdened if they spend more than 30% of their income on housing costs.

In this application exercise we will explore trends in the percentage of cost-burdened rental households in the 10 largest core-based statistical areas (CBSAs).¹ The relevant data can be found in data/cbsa-renters-burden.csv.

pct_burdened reports the percentage of renter-occupied housing units that spend 30%+ of their household income on gross rent.²

Communicating trends with a static visualization

Your turn: While Americans face rising housing costs, the percentage of cost-burdened households has not increased uniformly across the country. Design and implement a static visualization to communicate the trends for these 10 CBSAs. Ensure it can reasonably be used to identify trends specific to each CBSA.

Communicating trends with an interactive visualization

Your turn: Design and implement an interactive visualization to communicate the trends for these 10 CBSAs. Ensure it can reasonably be used to identify trends specific to each CBSA. Leverage interactive components to reduce clutter in the visualization and effectively utilize interactivity.

TipSuggestions include

• Using geom_line_interactive() and geom_point_interactive()
• Customizing the tooltip to provide better-formatted information
• Using girafe_options() to emphasize the hovered CBSA
