The Population Reference Bureau (PRB), a nonprofit educational organization, aims "to increase the amount, accuracy, and usefulness of information about population trends and their implications." In addition to general organizational information, PRB's Website provides a selection of full-text articles, excerpts of published reports, and statistical summaries related to world population studies. The News, Numbers, & Analysis section allows users to locate relevant documents quickly; pop-up menus guide users to collections arranged by population topic or geographic region.
