have your data be transferrable (and trackable) across social services you use.
have your data be collected directly at each social service you use and not shared.
Of course, these are not the only two options. I see many pros and cons around a much discussed topic, data portability. Done well, data portability can change the relationship about who gets to actually control and own their own data. Done poorly, data portability can make it very easy for external actors to surveille people using social services. Which would you like to see your sector moving towards? How would you like to see your own data stored? Have you had any experiences with these systems?
This is such a sticky issue! Wearing my researcher hat, well-done and privacy-preserving data portability could help us answer critical social questions that are hard to answer when different administrative data sources don’t align. Imagine how nice it would be to, for example, easily access housing/education/health/other social service data in one fell swoop - that’s the stuff of dreams!
But as a person who uses social services (and who knows that data portability is often not done well), the idea of such extensive data linkages is very troubling, even if it would reduce the burden of accessing these services. Such services have a long and fraught history of being co-opted for surveillance.
