Data in the public sector: Open data and research data

OpendataThe “open data” movement is radically transforming policy-making. In the name of transparency and openness the UK, US and other governments are releasing large amounts of records. It is a way to hold the government to account: in UK for example, all lobbying efforts in the form of meetings with senior officers are now publicly released. Data also enable the public to make more informed decisions: for example, using apps from public transport services to plan their journeys, or tracking indicators of, say, crime or air pollution levels in their area to decide where to buy property. Data are provided as a free resource for all, and businesses may use them for profit.

The open data movement is not limited to the censuses and surveys produced by National Statistical Institutes (NSIs), the public-sector bodies traditionally in charge of collecting, storing and analyzing data for policy purposes. It extends to other administrations such as the Department for Work and Pensions or the Department for Education in the UK, which also gather and process data, though usually through a different process, not using questionnaires but rather registers.

Big Data redefine what “markets” are

The growth of “big data” changes the very essence of modern markets in an important sense. Big data are nothing but the digital traces of a growing number of people’s daily transactions, activities and movements, which are automatically recorded by digital devices and end up in huge amounts in the hands of companies and governments. Payments by debit and credit cards record timing, place, amount, and identity of payer and payee; supermarket loyalty cards report purchases by type, quantity, price, date; frequent traveler programs and public transport cards log users’ locations and movements; and CCTV cameras in retail centers, buses and urban streets capture details from clothing and gestures to facial expressions.

This means that all our market transactions – purchases and sales – are identifiable, and our card providers know a great deal about our economic actions. Our consumption habits (and income and tastes) may seem more opaque to scrutiny but at least to some extent, can be inferred from our locations, movements, and detail of expenses. If I buy some beer, maybe my supermarket cannot tell much about my drinking; but if I never buy any alcohol, it will have strong reasons to conclude that I am unlikely to get drunk. As data crunching techniques progress (admittedly, they are still in their infancy now), my supermarket will get better and better at gauging my habits, practices and preferences.
