Select one or more filter values to narrow the dataset. Only records that match all of your selections will be displayed. After making your selections, click the "Apply Data Filters" button to apply the filters. Use the year range slider below to filter by date and the bounding box tool in Results to further limit the dataset to a specific area.
There are two options for selecting records based on the death date: you can use a range slider to select a year range, or you can use dropdowns to select a year and month range.
Select the desired start and end year and month from the respective dropdowns.
After you select an option and change the date, click the "Apply Data Filters" button to filter the data to the selected date range.
Try adjusting or clearing some filters to see results.
The interactive map below displays recorded migrant mortality locations along the United States–Mexico border. You can add or remove data layers using the layer control panel in the lower-left corner of the map. Click on individual points or other areas on the map to view additional information. To navigate the map, use the "Search for a location" box in the upper-left corner to locate a specific place, or use the "+" and "–" buttons in the upper-right corner to zoom in and out. The Home button returns the map to its default view, while the Geolocation button below it (an arrow pointing up and to the right) centers the map on your current location.
To filter migrant mortality locations by geographic area, select an option below and then click the “Apply Bounding Box Filter” button. The resulting map will display only locations that fall within the selected area and match any other filters you may have applied. Because the study area is located in the Northern and Western hemispheres, enter positive values in the North and South fields and negative values in the East and West fields.
The chart below displays the number of deaths by year, broken down by identification status. Each color represents one identification category. Hover over or tab into the chart to view the number of deaths for each category in a given year. The chart only displays deaths that match the current filter settings. Click "Table View" or "Chart View" to toggle between tabular and graphical displays of the data.

The horizontal bar charts below show the distribution of deaths across categories for the records that match the current filter settings. Each bar represents 100% of the records in that category, making it easy to compare proportions across categories. Categories with no matching records are not shown. Toggle the radio button below to display the values as either percentages or counts. To change filters, scroll back up to the filters section or click here to automatically scroll to the filters.

Manner of death represents the broad medicolegal classification of the circumstances surrounding a death, as reported by the source agency.
Cause of death represents the reported injury, condition, or environmental factor associated with a death, grouped into broader categories for comparison.
The table below lists the migrant death records that match the current filter settings. Each row represents one recorded death. Use the pagination controls to browse the records. By default, records are sorted by date, with the most recent records displayed first. Show or hide columns by selecting options in the "Show columns" dropdown. To pan the map to a given row, click the button labeled "Center the map on this location". The map will update to bring this record into view, and open its popup.
As part of our commitment to transparency, the M3P2 team has made the complete migrant mortality dataset available for public download, allowing users to explore the data, conduct their own analyses, and create maps, charts, and other visualizations.
