Number of state prisons per state

This map shows federal prison facilities in the United States. Not included (yet) are the roughly 400 other facilities used by ICE to house people in immigration-related cases.

The blue markers are federal facilities run by the Bureau of Prisons. The green markers are private prisons run by companies such as GEO Group. The red markers are non-federal facilities, such as state, county, city, etc.

This map does not show all the other facilities that are part of the prison industry. For example, the several hundred federal and state probation and pretrial offices.

Help using Google Maps

The Full Screen control in the upper righthand corner of the Google Maps display expands the display to cover the entire computer screen. This full-screen feature is not available on Apple IOS devices like the iPad.

You can exit out of full screen by pressing the Escape key or clicking the control in the upper righthand corner of the display.

Map Satellite Labels

The Map/Satellite control in the upper lefthand corner of the screen lets you choose either the normal map view or the satellite view. The satellite view allows you to see the actual military facility when you zoom in. You can choose to turn Labels on or off. The labels are the names of places, businesses, cities, etc. that appear on the map. You can turn off the labels if they obstruct your view.

Map Satellite Terrain

When you select the Map view, you can turn on terrain features by clicking or touching the Terrain box. This will show things like mountain ranges, similar to looking at a relief map.

You can zoom in and out in a few ways. The lower righthand corner of the Google Maps display has a plus sign and a minus sign that controls zooming. If you're using a mouse with a scroll wheel, the wheel controls zooming. If you're using an IOS device like an iPhone or iPad, double-tapping the display zooms in but tapping does not zoom out.

Most touch screen devices will zoom by pinching the display with two fingers.
