Allergy Statistics and Facts

Here’s a rundown of some of the most important allergy statistics — based on the best available data from WEBMD.

Allergy Statistics and Facts


  • $7.9 Billion: Annual cost of allergies to the health care system and businesses in the U.S.
  • 4 Million: Number of workdays lost each year as a result of hay fever: 4 million.
  • 33%: Odds that a child with one allergic parent will develop allergies
  • 70%: Odds that a child with two allergic parents will develop allergies
  • 1 in 5: Number of people in the U.S. who have either allergy or asthma symptoms
  • 55%: Percentage of the U.S. population that tests positive to one or more allergens

Asthma Statistics

  • 160%: Increase in the prevalence of asthma in U.S. children under age 5 between 1980 and 1994
  • 25%: Percentage of annual ER visits in the U.S. caused by asthma
  • 44%: Percentage of people hospitalized for asthma who are children
  • 5,000: Number of deaths each year in the U.S. from asthma
  • 30,000: Number of ER visits in the U.S. caused by food allergies each year

To Be an Allergy or Not To Be?

  • 1 out of 3: The number of people with chronic allergy-like symptoms — runny nose, congestion and cough –but who do not test positively for allergens.

This statistic means that people are having allergy symptoms but do not test for allergies. To me this means that the detection instruments are not sensitive enough of are not measuring the appropriate substances. Why would your immune system react to eliminate something if nothing is provoking the elimination response?
