The United States

• The number of people suffering from IBD (either Crohn’s disease or ulcerative colitis) in the United States is estimated to be 1.3% of US adults (3 million). 
• According to the Crohn’s and Colitis Foundation of America (CCFA), as many of 70,000 new cases of inflammatory bowel diseases (IBD) are diagnosed in the United States each year, and there are as many as 80,000 children in the United States with IBD. One of the most common types of IBDs is Crohn’s disease,
• In 2015, an estimated 3.1 million adults in the United States had received a diagnosis of IBD, and according to the Crohn’s & Colitis Foundation, Crohn’s disease may affect as many as 780,000 Americans.
• Most people with IBD are diagnosed in their 20s and 30s.

Germany

• In Germany, it is estimated that one to two in 1,000 people suffer from Crohn's disease.

France

• In France approximately 5 new cases of Crohn's disease and an equal number of ulcerative colitis cases are diagnosed each year per 100,000 inhabitants. 
•  France is projected to have the highest Annual Growth Rate (AGR) of diagnosed prevalent cases of CD at 4.04% 

Denmark

• The annual incidence of Crohn’s disease increased by about 75%, from 5.2 to 9.1 per 100,000 individuals between 1980 and 2010.
• The increase in annual incidence rates of Crohn’s disease was highest among patients aged younger than 15 years, while the increase in annual incidence rates of ulcerative colitis was highest among patients aged older than 15 years.
• Increases in Crohn’s disease incidence were seen among both sexes, but the incident rates were significantly higher in females. 

United Kingdom

• The prevalence of Crohn's disease in the UK is about 145 per 100,000 population. 
• In the UK, it is estimated that at least 115,000 people have Crohn's disease and around 146,000 have a diagnosis of ulcerative colitis.
• In more than 8 million total individuals, investigators observed 16,765 incident cases of Crohn’s disease and 24,410 incident cases of ulcerative colitis.

Sweden

• The Crohn's disease prevalence is reported as 29 per 100,000 population.
• Although most patients are adults, some 10–25% are diagnosed before 21 years of age.

Norway

• The incidence of Crohn's disease in western Norway was estimated in a prospective epidemiologic study during the years 1984 and 1985. The total population in the area was 807,000. 
•  505 per 100,000 people have ulcerative colitis in Norway.

Finland

•  2,000 new cases of inflammatory bowel disease (IBD) are diagnosed in Finland every year. Finland has seen an explosion in inflammatory bowel disease (IBD) cases including Crohn's disease since the chronic condition first became prevalent in the 1990s.
•  This study showed a high prevalence of IBD in Finland; in fact, 0.6% of the Finnish population has IBD, and in the age group 35–54 almost 1% suffers from it.

Spain

• Assuming an estimated prevalence of IBD in Spain of 180,000 cases, 40% are attributed to Crohn's disease.

Summary Of Our Early Findings Relevant To The Goals

• Our initial hour of research was spent trying to understand if the data asked for is publicly available. It was a mixed bag. While some countries like the United States, Canada (which was not asked for) and the United Kingdom appear to have readily available data, other countries did not have recent statistics. In fact Norway does not appear to have any recent data, but again we were only given one hour to research, so more digging is recommended in this case.
• It should be noted that Crohn's Disease very often is lumped in with ulcerative colitis, as well as IBD in general, and data has been provided on that when Crohn's disease statistics were not available.
• Both prevalence and incidence appear to be readily available for IBD, however, there was no data found that provided how long the average person has been dealing with the disease. In other words the number of years since diagnosis. We will not be pursuing that avenue. However, we did note that there was data surrounding how old someone was when they are first diagnosed.
• We will use the most up to date publicly available sources available, but we noted that for some countries, the most recent data was a decade or more older.
• We did not have time in the initial hour to drill down on demographics, but we did note that in almost all cases, we saw that age and gender were publicly available for most countries, but that could be for IBD in general, and not just for Crohn's disease.
