Use of Databases and Computer Technology
See also: Geographic information systemThe introduction of modern computers alongside the development of elaborate voter databases and special districting software has made gerrymandering a far more precise science. Using such databases, political parties can obtain detailed information about every household including political party registration, previous campaign donations, and the number of times residents voted in previous elections and combine it with other predictors of voting behaviour such as age, income, race, or education level. With this data, gerrymandering politicians can predict the voting behaviour of each potential district with an astonishing degree of precision, leaving little chance for creating an accidentally competitive district.

Famous quotes containing the words computer and/or technology:
“What, then, is the basic difference between today’s computer and an intelligent being? It is that the computer can be made to see but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of pattern—a capacity essential to perception and intelligence.”
—Rudolf Arnheim (b. 1904)
“One can prove or refute anything at all with words. Soon people will perfect language technology to such an extent that they’ll be proving with mathematical precision that twice two is seven.”
—Anton Pavlovich Chekhov (1860–1904)
