The study aims to investigate people’s awareness regarding the potential use of their data by platforms and administrations, as well as the motivations behind their caution or willingness to share data with public or private entities. Additionally, it seeks to understand the reasons driving citizens to adopt privacy-protective behaviors.

The dataset used in this research includes responses to a questionnaire that captured users’ sociodemographic characteristics, political preferences, their level of knowledge on privacy-related topics, and answers to a series of specific questions designed to analyze citizens’ attitudes towards granting their data to third parties.

Data collection was conducted through a survey conducted via online interviews (CAWI) for two-thirds of the sample and through telephone interviews (CATI) for the remaining third.


More specifically, the following topics were discussed:

  • possession of digital devices, and operating system used
  • frequency of use of digital device features
  • subscriptions to social networks
  • collection of personal data by digital platforms: types of data collected and legal aspects
  • use of personal data by public administrations
  • trust in digital companies
  • measures taken to protect personal data
  • willingness to pay for platform subscriptions to better protect personal data and/or willingness to receive money in exchange for giving up more personal data
  • ability to effectively protect personal data
  • interest in seeing ads and news on platforms that correspond to your preferences
  • access to devices and platforms by children and young people.
