Hi Michael,
This is from the net:

-Pernicious anaemia has an incidence of 1:10,000 in Northern Europe, and accounts for 80% of cases of megaloblastic anaemia [Hoffbrand and Provan, 2007].
-A cross-sectional study of 3511 people, 65 years of age or older, investigated the prevalence of vitamin B12 and folate deficiency (with or without anaemia) [Clarke et al, 2004]:
-The prevalence of vitamin B12 deficiency was around 5% in people 65–74 years of age, and more than 10% in people 75 years of age or older.
-The prevalence of folate deficiency was similar to that of vitamin B12 deficiency.
-Of people with low vitamin B12 levels, only 10% had low folate levels.
-Vitamin B12 deficiency is unusual in younger people, except those eating strict long-term vegan diets [British Columbia Medical Association, 2006].
