ICTworks

The November 14, 2012, Technology Salon NYC (TSNYC) focused on ways that ICTs can support work with children who migrate. An earlier post covers the discussion around Population Council’s upcoming ‘Adolescent Girls on the Move’ report. The current post focuses on the strategic use of data visualization for immigration advocacy, based on opening points from Brian Root and Enrique Piracés of Human Rights Watch (HRW).

The project

The HRW initiative used data to track and visualize the movement of people through the US immigration detention system after noticing that U.S. Immigration and Customs Enforcement (ICE) was moving people very freely without notifying their families or attorneys. HRW was aware of the problem but not its pervasiveness. The team obtained some large data sets from the US government via Freedom of Information Act (FOIA) requests. They used the data to track individuals’ routes through the immigration detention system, eventually mapping the whole system out at both aggregate levels and the level of individual. The patterns in the data informed HRW’s advocacy at the state and federal levels. In the process, HRW was able to learn some key lessons on advocacy and the importance of targeting data visualizations to specific advocacy purposes.

Data advocacy and storytelling

The data set HRW obtained included over 5.4 million records of 2.3 million people, with 10-12 variables. The team was able to connect these records to individuals, which helped tell a meaningful story to a broad audience. By mapping out all the US facilities involved and using geo-location to measure the distance that any individual had been transferred, the number of times an individual from Country X in Age Range X was transferred from one facility to another was visible, and patterns could be found. For example, often people on the East Coast were transferred to Texas, where there is a low ratio of immigration lawyers per detainee.

Even though the team had data and good stories to tell with the data, the two were not enough to create change. Human rights are often not high priority for decision makers, but budgeting is; so the team attached a cost to each vector that would allow HRW to tell decision makers how much was being spent for each of these unnecessary transfers.

They were also able to produce aggregated data at the local level. They created a state dashboard so that people could understand the data at the state level, since the detention facilities are state-run. The data highlighted local-level inefficiencies. The local press was then able to tell locally relevant stories, thus generating public opinion around the issue. This is a good example of the importance of moving from data to story telling in order to strengthen advocacy work.

HRW conveyed information and advocated both privately and publicly for change in the system. Their work resulted in the issuing of a new directive in January 2012.

FOIA and the data set

Obtaining data via FOIA acts can be quite difficult if an organization is a known human rights advocate. For others it can be much easier. It is a process of much letter sending and sometimes legal support.

Because FOIA data comes from the source, validation is not a major issue. Publishing methodologies openly helps with validation because others can observe how data are being used. In the case of HRW, data interpretations were shared with the US Government for discussion and refutation. The organization’s strength is in its credibility, thus HRW makes every effort to be conservative with data interpretation before publishing or making any type of statement.

One important issue is knowing what data to ask for and what is possible or available. Phrasing the FOI request to obtain the right data can be a challenge. In addition, sometimes agencies do not know how to generate the requested information from their data systems. Google searches for additional data sets that others have obtained can help. Sites such as CREW (Citizens for Responsibility and Ethics in Washington), which has 20,000 documents open on Scribd, and the Government Attic project, which collects and lists FOI requests, are attempting to consolidate existing FOI information.

The type of information available in the US could help identify which immigration facilities are dealing with the under-18 population and help speculate on the flow of child migrants. Gender and nationality variables could also tell stories about migration in the US. In addition, the data can be used to understand probability: If you are a Mexican male in San Jose, California, what is the likelihood of being detained? Of being deported?

The US Government collects and shares this type of data, however many other countries do not. Currently only 80 countries have FOI laws. Obtaining these large data sets is both a question of whether government ministries are collecting statistics and whether there are legal mechanisms to obtain data and information.

Data parsing

Several steps and tools helped HRW with data parsing. To determine whether data were stable, data were divided by column and reviewed, using a SHELL. Then the data were moved to a database (MySQL), however other programs may be a better choice. A set of programs and scripts was built to analyze the data, and detention facilities were geo-located using GeoNames. The highest quality result was used to move geo-location down to the block level and map all the facilities. Then TileMill and Quantum GIS (QGIS) were used to make maps and ProtoViz (now D3) was used to create data visualizations.

Once the data were there, common variables were noted throughout the different fields and used to group and link information and records to individuals. Many individuals had been in the system multiple times. The team then looked at different ways that the information could be linked. They were able to measure time, distance and the “bounce factor”, eg.., how many times an individual was transferred from one place to the other.

Key learning:

Remember the goal. Visualization tools are very exciting, and it is easy to be seduced by cool visualizations. It is critical to keep in mind the goal of the project. In the HRW case the goal was to change policy, so the team needed to create visualizations that would specifically lead to policy change. In discussions with the advocacy team, they defined that the visualizations needed to 1) demonstrate the complexity 2) allow people to understand the distance 3) show the vast numbers of people being moved.

Privacy. It is possible to link together individual records and other information to tell a broader story, but one needs to be very careful about this type of information identifying individuals and putting them at risk. For this reason not all information needs to be shared publicly for advocacy purposes. It can be visualized in private conversations with decision makers.

Data and the future

Open data, open source, data visualization, and big data are shaping the world we are embedded in. More and more information is being released, whether through open data, FOIA or information leaks like Wikileaks. Organizations need to begin learning how to use this information in more and better ways.
