BACKGROUND: Ageing European populations put pressure on national blood supplies, increasing the need for blood and donor base rejuvenation. Therefore, we investigate how European countries' blood donor populations differ and how they have evolved over the last 2 decades. Previous comparative research, based on 1994 Eurobarometer data, indicate that the typical donor is an educated, middle-aged, white, married male. Other sociodemographic and socioeconomic correlates, such as employment status and type of community, are less clear. STUDY DESIGN AND METHODS: Multilevel analyses are performed on repeated cross-level data from the Eurobarometer (waves 1994, 2002, 2009, and 2014) to compare information on "ever having donated" across sociodemographic categories, countries, and periods. RESULTS: There are consistent but moderate country and period differences. The donor population rose to become largest in most countries by 2009, and stabilized thereafter. Over the studied period, donors were more likely to be higher educated, married men. Nevertheless, changes across time in donor profiles within countries did occur. Women were less likely to donate blood, especially in Southern and Eastern Europe, but this gender gap has declined. Furthermore, educational attainment seems more relevant for women, although, more recently, to a lesser extent. CONCLUSION: Although there is a promising trend in which women, young people, and students are increasingly likely to donate, more attention is needed to reach the unemployed and the low to medium educated. Because the unemployed may lack structural opportunities to donate, and the low to medium educated may lack relevant knowledge on blood donation necessity, we recommend providing practical opportunities and information on the necessity of blood donation.
