==Overview==
Incidence of temporal arteritis ranges from approximately 0.5 to 27 cases per 100,000 people aged 50 years or older. The incidence of temporal arteritis increases with [[Ageing|age]]; the median [[age]] at diagnosis is 76.7 years. Temporal arteritis commonly affects individuals older than 70 years of age. Temporal arteritis usually affects individuals of the white race. Black, Asians, and Hispanic individuals are less likely to develop temporal arteritis. Women are more commonly affected by temporal arteritis than men. The [[female]] to [[male]] ratio is approximately 3 to 1. The highest incidence of temporal arteritis is reported in Scandanavian countries at 32.7 per 100,000 people for people over 50 years of age.

Because temporal arteritis is a disease of the elderly, the prevalence of the disease is very dependent upon the age of the population. As a result, there is a lower prevalence in countries with a shorter or reduced life expectancy.

===Race===
 
It is more prevalent in caucasians.
=== Region ===
===Prevalence===
Most likely as a result of increased clinical recognition of the syndrome, the incidence of temporal arteritis increased between 1950 and 1975 from 5.1 to 17.4 incident cases per 100,000 population per year in persons aged 50 years and older in Olmsted County, Minnesota. More recently in this population, the prevalence was even higher at 133 cases per 100,000 in persons aged 50 years and older.


There is not much data regarding the prevalence of disease outside the US, but given the variation in life expectancy and demographics, the prevalence is thought to vary significantly. The highest reported rates of disease outside the US are in Scandinavia, where the prevalence is 23.3-33.6 per 100,000 people older than 50 years.

Overview

Incidence of temporal arteritis ranges from approximately 0.5 to 27 cases per 100,000 people aged 50 years or older. The incidence of temporal arteritis increases with age; the median age at diagnosis is 76.7 years. Temporal arteritis commonly affects individuals older than 70 years of age. Temporal arteritis usually affects individuals of the white race. Black, Asians, and Hispanic individuals are less likely to develop temporal arteritis. Women are more commonly affected by temporal arteritis than men. The female to male ratio is approximately 3 to 1. The highest incidence of temporal arteritis is reported in Scandanavian countries at 32.7 per 100,000 people for people over 50 years of age.
