In 1999, ORC Macro's MEASURE DHS+ project and the U.S. Bureau of the Census teamed together, along with SerPro S.A., to develop a Windows-based software package to replace the existing DOS-based packages. Those packages had been used for more than 15 years as the standards for Demographic and Health Survey processing and census processing in developing countries. The resulting software is CSPro.

CSPro combines and expands upon the capabilities of both ISSA and IMPS. It takes advantage of the power and flexibility of both of these programs, but adds the friendliness, ease of use, and intuitive nature of Windows. CSPro provides a more visual approach to the creation and manipulation of data and reduces the programming needs. This easy to use package facilitates defining data structures, developing applications, entering and checking data, generating reports, and producing tabulations. More advanced users, including computer programmers, can access the full CSPro language to perform complicated tasks.

CSPro consists of modules for Data Entry, Batch Editing and Processing, and Cross Tabulation, as well as Designer modules for creating Data Dictionaries and Data Entry Forms, and for writing applications. It also includes a set of tools, including Text Viewer, Table Viewer, Map Viewer, Table Retrieval, Tabulate Frequencies, Sort Data, Export Data, Reformat Data, Compare Data, Convert Dictionary, and Convert Shape to Map.
