Systemic lupus erythematosus
The rate of SLE varies between countries, ethnicity, and sex, and changes over time. In the United States, one estimate of the rate of SLE is 53 per 100,000; other estimates range from 322,000 to over 1 million. In Northern Europe the rate is about 40 per 100,000 people. SLE occurs more frequently and with greater severity among those of non-European descent. That rate has been found to be as high as 159 per 100,000 among those of Afro-Caribbean descent. Childhood-onset systemic lupus erythematosus generally presents between the ages of 3 and 15 and is four times more common in girls.
Lupus Foundation of America
The Foundation provides answers to questions and gives caring support to people with lupus and their loved ones. The organization works with lupus experts to answer questions, provide tools, resources and referrals to doctors who treat lupus, and help guide all those affected by lupus toward a better quality of life. 
In 2016, the Foundation conducted a National Needs Assessment on Lupus to take a broad, yet in-depth look at the very specific needs and wants of the diverse lupus patient, caregiver and health care professional communities. In response, the Foundation created the National Resource Center on Lupus – a one-stop resource for all things lupus. 
The National Resource Center on Lupus aims to connect, empower and educate those whose lives are impacted by lupus by providing trustworthy, reliable and high-quality resources, programs and emotional support services.
The Foundation also developed more than 600 medically-reviewed resources in English and Spanish about all aspects of lupus. New content is added on a regular basis developed in response to the needs of the lupus community. Children and teens with the disease can find specialized content created just for them based on their input and unique perspectives. 
. Through their National Health Educator Call Center and programs conducted by their National Network, the organization provides direct education, support and referrals for more than 40,000 people. They also provide information to nearly 9 million people through their website annually.
