Lifetime, 5-year and past-year prevalence of homelessness in Europe: a cross-national survey in eight European nations

Objectives To examine the lifetime, 5-year and past-year prevalence of homelessness among European citizens in eight European nations.Design A nationally representative telephone survey using trained bilingual interviewers and computer-assisted telephone interview software.Setting The study was conducted in France, Ireland, Italy, the Netherlands, Poland, Portugal, Spain and Sweden.Participants European adult citizens, selected from opt-in panels from March to December 2017. Total desired sample size was 5600, with 700 per country. Expected response rates of approximately 30% led to initial sample sizes of 2500 per country.Main outcome measures History of homelessness was assessed for lifetime, past 5 years and past year. Sociodemographic data were collected to assess correlates of homelessness prevalence using generalised linear models for clustered and weighted samples.Results Response rates ranged from 30.4% to 33.5% (n=5631). Homelessness prevalence was 4.96% for lifetime (95% CI 4.39% to 5.59%), 1.92% in the past 5 years (95% CI 1.57% to 2.33%) and 0.71% for the past year (95% CI 0.51% to 0.98%) and varied significantly between countries (pairwise comparison difference test, p1.5).Conclusions The prevalence of homelessness among the surveyed nations is significantly higher than might be expected from point-in-time and homeless service use statistics. There was substantial variation in estimated prevalence across the eight nations. Coupled with the well-established health impacts of homelessness, medical professionals need to be aware of the increased health risks of those with experience of homelessness. These findings support policies aiming to improve health services for people exposed to homelessness.
