This Glossary of Common Data Terms was developed locally as a non-technical resource for those interested in expanding their functional data vocabulary. This glossary contains commonly used data terms defined in easy-to-understand language. Although the definitions are informal and non-academic, the following academic texts heavily informed their development:

Shryock, H.S., and Siegel, J.S. The Methods and Materials of Demography. San Diego, CA: Academic Press, 1976.
Haupt, A. and Kane, T.T. Population Handbook. Washington, DC: Population Reference Bureau, Inc., 1978.
