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%.
对居住在南巴登的3933人（2202名本地人，1731名移民）进行横断面研究，调查甲状腺肿的发病率及其与当地规模的关系，并将结果与我们1963年在相同条件下得到的研究结果进行比较。1973年，接受检查的本地人口中只有24.3%患有甲状腺功能正常的甲状腺肿，而1963年这一比例为47.0%。移民人口中的甲状腺肿发病率也下降了约一半。1973年，本地人口中甲状腺肿患者比移民人口中多9.4%。在较大的城镇，1963年至1973年期间，本地人口中甲状腺肿的发病率从约40%降至不到20%，在农村地区从约60%降至40%。农村地区移民人口中甲状腺肿病例的总发病率从约40%降至30%，移民到城镇的人口中从20%降至10%。
