Roma and Travellers in the WHO European Region are vulnerable to deep, long-lasting poverty and ill health. Their status is shaped by a variety of factors, especially high unemployment, substandard housing conditions, poor access to health services, and direct and indirect discrimination. Roma live in almost all European and central Asian countries. Population figures and other data on them are scarce and controversial. The European Parliament has estimated there are between 12 million and 15 million Roma and Travellers, with between 7 million and 9 million living in the EU. Roma in eastern Europe and central Asia are primarily settled, while some in western Europe continue to pursue a nomadic lifestyle. Many Travellers also move around. Due in part to changing economies and deepening exclusion in eastern Europe, rural- to-urban labour migration and economically motivated immigration also occur–frequently from eastern to western Europe
