Questions & Answers

Q: What is the significance of missing data in vulnerable communities?

Missing data in vulnerable communities exacerbates their marginalization as it hinders the allocation of essential resources. Without accurate data, it's challenging to understand their needs and develop targeted interventions.

Q: How did the speaker overcome the lack of data on Nairobi's informal transit system?

The speaker leveraged mobile phone data and created an app to collect information on the movement of buses. This data was then used to develop a model and eventually create a map that facilitated better understanding of the system.

Q: How did visualization impact policy-making in relation to migration?

By presenting the migration data in an interactive and accessible format, policymakers were able to gain insights and make informed decisions. The visualization revealed the significant costs associated with migration and influenced the opening of legal pathways for Central American migrants.

Q: How did the speaker engage migrants in telling their own stories?

The speaker created a tapestry of motivations, representing the reasons behind migration, and used it as inspiration to create a physical tapestry made of money. Each dollar had a chip that could be tapped to hear a migrant's story, giving them a voice in the narrative.

Summary & Key Takeaways

• The speaker talks about the era of "Big Data" but highlights the existence of missing data in many countries, which further marginalizes vulnerable communities.

• The first example focuses on Nairobi, where the speaker used mobile phone data to create a model of the city's informal transit system, which had a significant impact on policy-making.

• The second example involves collecting data from migrants and transforming it into an interactive visualization to raise awareness and influence policy decisions.
