# CSPro

CSPro, short for the Census and Survey Processing System, is a public domain and Open source data collection and processing software package developed by the U.S. Census Bureau and ICF International. Serpro S.A. was involved in past development. Funding for development comes primarily from the U.S. Agency for International Development. The main purpose of this software suite is to design applications for data collection, processing and tabulation.
CSPro was designed and implemented through a joint effort by the developers of two earlier software packages that were used to capture, edit, and tabulate census and survey data on DOS-based machines: the Integrated Microcomputer Processing System (IMPS), developed by the U.S. Census Bureau, and the Integrated System for Survey Analysis (ISSA), developed by Serpro S.A. As a result, CSPro is founded on more than 35 years of development.
The software can be run on Windows-based OS (8,10 and 11—Linux and IOS operating systems are not supported) to design applications able to be deployed on Android and Windows family OS following its "Build Once, Deploy Many" ability. These applications can be used for mobile survey data collection (via Smartphones or tablets), or for office-based collection (via laptops or desktops). The public domain distribution is open source. Support for Unicode data entry began with version 5.
A CSPro designed application can be a dynamic and intelligent questionnaire for entering, editing, tabulating, mapping, and disseminating census and survey data. Also, the simple IDE of the CSPro Designer can be used to implement sophisticated Information System in various fields such as Monitoring and Evaluation, Business Administration, Logistics and so on.
This package is widely used worldwide by statistical agencies, international organizations, NGOs, consulting firms, colleges and universities, hospitals, and private sector groups, in more than 160 countries. Major international household survey programs, such as Multiple Indicator Cluster Surveys (MICS) and Demographic and Health Surveys (DHS) also use CSPro for Census and Survey works.
While the program uses a simple graphical interface (IDE), CSPro also contains a sophisticated programming language that can be used to create highly customized applications. Beginning users can program simple quality control checks, and advanced users can write dynamic applications using his procedural and object oriented programming language.
It remains actively in development (as of Winter 2025). With latest improvements, CSPro designed application support:
* SQLite and SQL language;
* Relational database support on device and servers;
* Improved data security through transparent data encryption and support of best in class hashing/salting algorithms;
* Multiple questions per screen;
* Mobile Mapping: Displaying dynamic mapping and deal with geographic informations (online maps, Tiled offline basemap and points (all features: polygon, polyline, line is supported on version 7.7));
* Introduction of Objects programming in CSPro logic;
* CSS, HTML5, JavaScript via templated report, CAPI text, Webview/Webview 2 and CSPro-Javascript interface;
* PHP through CSWeb;
* Powerful and comprehensive paradata for complete and intelligent monitoring of the data collection step;
* Smart application installation using barcode/QR Code;
* Multiple programming language improvements (smart synchronization (including on local Dropbox and FTP servers, dynamic translation, etc.));
The source code of the CSPro software Suite: CSPro Designer, CSEntry Windows and Android, CSPro Help Documentation, CSWeb API have been released to the public. And starting 2025, CSPro become an open source project. In addition to the help system disseminated with CSPro, an active users forum is maintained as well.
