Column 1 is not labeled, with entries coal, grain, and iron and steel. Column 2 is labeled 1913, with entries 29, 80, 8.5. Column 3 is labeled 1921, with entries 9, 37.6, 0.3. Column 4 is labeled 1928, with entries 35, 73.3, 7.3. What is the best conclusion that can be drawn from this table?

The constant presence of diseases or infectious agents within a given geographic area or population group. it may also refer to the usual prevalence of a given disease with such area or group. it includes holoendemic and hyperendemic diseases. a holoendemic disease is one for which a high prevalent level of infection begins early in life and affects most of the child population, leading to a state of equilibrium such that the adult population shows evidence of the disease much less commonly than do children (malaria in many communities is a holoendemic disease). a hyperendemic disease is one that is constantly present at a high incidence and/or prevalence rate and affects all groups equally. so probably family history.
