FAQs About the History of Geological Surveys

The U.S. Census Bureau has a long history of geographic innovation. James D.B. DeBow produced the first map in a census publication in 1854, and by the end of the 19th century, the first statistical atlases were produced. In the 20th century, innovations in computing enhanced the ability to produce maps and link maps and global positioning systems.

These questions are some of the most frequently asked about the Census Bureau's geographic programs.

To aid in collecting data during the 1990 census, the Census Bureau developed the "Topologically Integrated Geographic Encoding and Referencing" (TIGER) system. Using the U.S. Geological Survey's maps, TIGER added additional information (roads, rivers, railroads, etc.) to create maps that are the basis for the global positioning systems many people have on their smartphone maps applications.
