HayStack is a tool to explore Point in Time data provided by the U.S. Department of Housing and Urban Development across the 25 metro areas involved in the 25 Cities Initiative (Continuums of Care).

The bar chart below compares different variables with unsheltered persons per capita (1000 persons). The size of the circles on the map below represent the unsheltered persons per capita, while the darkness of a circle represents a higher density of the comparison variable.

Select a variable to animate the chart and map. Click on a metro on the bar chart below or any circle on the map to highlight a specific city.
