Census Tract Maps
Census tract boundaries are fairly stable, but some tracts change at each decennial census since they are designed to be relatively homogeneous units ranging between 2,500 and 8,000 residents.

What to Do if the GIF Appears Unreadable (Internet Explorer Users Only)
Internet Explorer (by default) scales graphics to the browser size; thus, if your window is smaller than the graphic, IE scales the image down on the fly rather than popping up scroll bars. If you hover over the image, an expand button pops up (view screenshot ).
For those who find this functionality annoying, you can change this default behavior. From the toolbar, click Tools > Internet Options > Advanced Tab. Then scroll down to Multimedia and uncheck the “Enable Automatic Image Resizing” button. (Depending on your version of IE, the wording may differ slightly). Now whenever you look at a graphic, it will display at the size it was intended to, with scrollbars if needed.
