State Data is a series of HyperCard stacks that presents a tremendous amount of information about the 50 states. These well-designed and -integrated stacks can be a useful resource for teachers. There are some flaws, however. The data sources are several years old. If you want more-current data, you must gather and enter it. The sports focus is entirely on professional teams. State Data is a nice supplement to a social studies or geography course, but it isn’t a stand-alone tool.
