  1. The data were obtained from the National Tuberculosis Registry and Statistics Norway, and are sorted according to sex and age per 100,000 population in 10 year cohorts. Values represent annual rates of tuberculosis per 100,000 population. By combining the data from the birth cohort and age group it appears that the data are derived from the years 19481, 19582, and similarly from 1968, 1978 and 1988.
