DHS Program Indicator Data API Opens Door for Innovative Apps

On the heels of the White House’s commitment to open data, Blue Raster collaborated with ICF International under The Demographic and Health Surveys (DHS) Program to build the DHS Indicator Data Application Programming Interface (API). Funded by the United States Agency for International Development (USAID), the API provides users direct access to over 30 years of Demographic and Health Survey (DHS) data for more than 90 countries covering almost 1,500 indicators – more than 3 million records. By using this tool, developers, analysts, and researchers can obtain DHS data programmatically and develop applications that suit their needs.

The API was developed by Blue Raster on the ColdFusion Web Application platform. Developers can query the DHS data using both a RESTful interface, which allows selecting parameters including countries, indicators, and surveys, as well as a conventional query-based interface which provides advanced options for obtaining more customized results. For those looking to query large sets of data, the API offers additional parameters that control the format, citation, and version information. Additionally, JSON, XML, CSV and HTML output formats are supported to provide users with flexibility.

DHS Program API Application Showcase

In the spirit of openness, the DHS Program has put together tips and code samples in JavaScript, ColdFusion, .NET, Python, R, Stata, and more to help users get started. You can even register to be a DHS API partner which allows you access to a larger number of entries returned per page and assistance in application development.

Trever Croft, DHS Program’s Capacity Strengthening Technical Coordinator, says:

“The DHS API provides a new level of access to DHS data. Blue Raster has produced a wonderfully simple but powerful tool that will power both the DHS website and STATcompiler as well as users and developers own applications.”

MEASURE DHS Releases New Website, STATcompiler

The new MEASURE DHS website (www.measuredhs.com) and STATcompiler (www.statcompiler.com) were launched today, introducing the global community to new ways of visualizing Demographic and Health Surveys data. New features of the website include an interactive map of countries and surveys, an enhanced publications library, and more information on survey methodology.  The new, more user-friendly STATcompiler features customized tables, as well as charts, maps, and scatter plots.

STATcompiler has always allowed users to create custom tables, comparing survey results across countries and over time. Now users can visualize these data through interactive column charts, line graphs, maps, and scatter plots.  Users can select indicators and countries of interest, add background characteristics such as age, education, and wealth, and instantly see in a chart what is hard to discern in a table. These images are exportable for use in papers and presentations.  Data tables have also been enhanced, allowing users to sort data and customize their view.

The MEASURE DHS web tools allow for the sharing of Demographic and Health Surveys data from 90 countries and over 260 surveys.  Data are made available through free publications, datasets, and online data visualization tools. The website also provides background information on the survey process and methodology, contextual information on health and demographic topics, and summary data on countries and topics of interest.

Blue Raster collaborated with ICF Macro to build this application using ArcGIS Server, Flex API, ColdFusion, and CommonSpot.  The MEASURE Demographic and Health Surveys Project is funded by the United States Agency for International Development (USAID).
