The U.S. Food Insecurity dashboard tracks the national rate of food insecurity by aggregating academic, governmental and nonprofit survey data. As more papers are published and surveys are released, we update this dashboard to better estimate trends in insecurity over time. We invite users to forward old and new datasets that are not included to cfdas@purdue.edu to help develop the most accurate survey average. Future data visualizations included on this dashboard will attempt to track trends such as the rate of food bank/pantry use.


Select the desired trend line using the panel on the left. Hover over the scatterplot to see the tooltip with expanded information. Click the legend on the right to highlight or remove values.


Food insecurity: A measure indicating that a household has experienced limited access to adequate food due to a lack of money and other resources. Each survey might use a slightly different method to define and collect data on rates of ‘food insecurity,’ but we only include studies that demonstrate they have used a validated measure. Typically, this measure is some form of the U.S. Department of Agriculture Household Food Security Module.

Date: The approximate day on which the survey data collection was completed or end of the reference period for the given food insecurity measure. Because food insecurity is typically measured over a specific timeframe and survey data is collected over multiple days, we pick a single date to represent one observation of the food insecurity rate.

Rolling Average: Unweighted mean of 10 most recent data-points.

Local Regression: Locally estimated scatterplot smoothing (LOESS) with a span of 0.3.

Linear by dataset: Linear regression of datasets with more than one observation.
