Global Psoriasis Atlas

The first atlas of its kind showing the global distribution of psoriasis. A dynamic, informative and accessible web-based atlas.

When the WHO Global Report on Psoriasis called for greater understanding of psoriatic disease epidemiology, the Global Psoriasis Atlas (GPA) was formed. The project is a long term collaboration between IFPA, the International league of Dermatological Societies (ILDS) and the International Psoriasis Council (IPC).

The GPA is the world’s most extensive review of the global burden of psoriasis and provides open access information about the worldwide epidemiology of psoriasis. Its results provide the scientific foundation to fuel IFPA's advocacy.

According to 2020 systematic review it is estimated that at least 60 million people worldwide are living with psoriasis. However, the prevalence appears to vary depending on genetic background and geographic location, and more than 80% of countries lack epidemiological data on psoriatic disease.


The Global Psoriasis Atlas is the leading epidemiological resource on psoriasis globally; thus informing research, policy and health care provision for the disease worldwide.


The mission of the GPA is to provide the common benchmark on the complete burden of psoriasis in all countries and regions throughout the world. The GPA will leverage existing data from publications and registries; where gaps are identified additional studies will be commissioned.

The GPA is a longterm project that seeks to drive continuous improvement in the understanding of psoriasis and to uncover how it affects both the individual and society at large. Whilst the first edition of the GPA will focus on the incidence and prevalence of psoriasis, future additions will be expanded to include access to treatment, comorbidities and cost to society.

In 2014, the World Health Organization approved the Resolution on Psoriasis. Shortly thereafter, the Global Report on Psoriasis (2016) was published, highlighting the need for an international atlas to map the burden of disease. These landmarks paved the way for the Global Psoriasis Atlas (GPA).

Since 2019, the Global Psoriasis Atlas has been available in an interactive website format. One of the GPA’s aims is to improve the understanding of psoriasis among different groups of people in every region worldwide, while meeting the highest scientific standards of epidemiological research. In addition to collecting previously published data on psoriasis, the GPA unleashes new findings on the prevalence of psoriasis among adults and children, associated comorbidities, and healthcare access.

The Global Psoriasis Atlas website presents the human face of psoriatic disease by sharing compelling, first-hand experiences from around the world. The faces and stories of our very own IFPA members are featured on the GPA website, revealing the deep impact of psoriatic disease and the true value of the GPA's work.

The GPA published the world’s largest systemic review of global data on the burden of psoriasis in the British Medical Journal.

The Global Psoriasis Atlas is now available in Spanish!

The GPA is a collaboration between three leading international organizations in world dermatology: International Federation of Psoriasis Associations (IFPA); International League of Dermatological Societies (ILDS); and International Psoriasis Council (IPC). This long-term project is led and delivered by global experts and led by the academic team at the University of Manchester working in collaboration with research organization from around the world.
