Allergic conditions: Statistics and epidemiology

Allergy type	United States	United Kingdom^[106]
Allergic rhinitis	35.9 million^[107] (about 11% of the population^[108])	3.3 million (about 5.5% of the population^[109])
Asthma	10 million have allergic asthma (about 3% of the population). The prevalence of asthma increased 75% from 1980 to 1994. Asthma prevalence is 39% higher in African Americans than in Europeans.^[110]	5.7 million (about 9.4%). In six- and seven-year-olds asthma increased from 18.4% to 20.9% over five years, during the same time the rate decreased from 31% to 24.7% in 13- to 14-year-olds.
Atopic eczema	About 9% of the population. Between 1960 and 1990 prevalence has increased from 3% to 10% in children.^[111]	5.8 million (about 1% severe).
Anaphylaxis	At least 40 deaths per year due to insect venom. About 400 deaths due to penicillin anaphylaxis. About 220 cases of anaphylaxis and 3 deaths per year are due to latex allergy.^[112] An estimated 150 people die annually from anaphylaxis due to food allergy.^[113]	Between 1999 and 2006, 48 deaths occurred in people ranging from five months to 85 years old.
Insect venom	Around 15% of adults have mild, localized allergic reactions. Systemic reactions occur in 3% of adults and less than 1% of children.^[114]	Unknown
Drug allergies	Anaphylactic reactions to penicillin cause 400 deaths per year.	Unknown
Food allergies	About 6% of US children under age 3 and 3.5–4% of the overall US population.^[^citation needed^] Peanut and/or tree nut (e.g. walnut) allergy affects about three million Americans, or 1.1% of the population.^[113]	5–7% of infants and 1–2% of adults. A 117.3% increase in peanut allergies was observed from 2001 to 2005, an estimated 25,700 people in England are affected.
Multiple allergies (Asthma, eczema and allergic rhinitis together)	Unknown	2.3 million (about 3.7%), prevalence has increased by 48.9% between 2001 and 2005.^[115]
