How rare does a medical condition have to be to be considered rare? I'm hoping for an answer like an x number of cases, or incidences/100,000 or x/1,000,000 etc. I am asking both for the technical answer and for opinions as well.

In the US there is a Rare Disease Act defining Rare:
The Rare Disease Act of 2002 (HR 4013) and the US Orphan Drug Act define a rare disease or condition as one that "(A) affects less than 200,000 persons in the United States, or (B) affects more than 200,000 in the United States and for which there is no reasonable expectation that the cost of developing and making available in the United States a drug for such disease or condition will be recovered from sales in the United States of such drug." Statistically speaking, with a population of 287,400,000, that means roughly .07% of the US population.
In Europe Rare is considered to be 0.05% (< 5 in 10,000)
