The incidence of goiter and its dependence on the size of the locality are examined in a cross-section of 3.933 people living in South Baden (2.202 natives, 1.731 immigrants) and the results compared with our findings in 1963 obtained under the same conditions. In 1973 only 24.3% of the native population examined had a euthyroid goiter compared with 47.0% in 1963. The incidence of goiter has also decreased by about half among the immigrant population. In 1973 9.4% more people with goiter could be found among the native population than among the immigrants. In the larger towns, the frequency of goiter among the native population fell between 1963 and 1973 from about 40% to less than 20% and in country areas from about 60% to 40%. The total frequency of goiter cases among the immigrant population in country areas fell from about 40% to 30% and in the immigrants to towns from 20% to 10%.
