ACCESS4ALL examines whether policymakers are accessible to all lobbyists, regardless of their societal background. Ideally, policymakers exchange with lobbyists with different socio-demographic profiles. Yet, the ACCESS4ALL project expects that policymakers predominantly exchange with lobbyists who resemble them; lobbyists of the same age, gender and ethnic background. We test our expectations within the European policy context through desk research, focus groups, large-scale surveys and vignette experiments. Based on our research, we propose strategies to make access to EU policymakers more open and inclusive.
