The geographic location of 18 major manufacturing industries within the United States is illustrated by a series of computer-generated county maps. The metal and machinery industries, the two largest employers, an the transportation and rubber industries are concentrated in the northeastern quadrant of the United States, while most counties with textile, apparel, tobacco, and furniture manufacturing are in the South. Other industries had different patterns. The counties where industry was concentrated tended to be more urban and to have higher levels of income and education. The maps and associated demographic data on industrial counties may prove a useful adjunct to county maps illustrating mortality patterns for cancer and other diseases. Despite obvious limitations, the visual patterns and correlation analyses may help to generate and formulate hypothese concerning occupationally induced diease.
一系列由计算机生成的县级地图展示了美国18个主要制造业在美国的地理位置。金属和机械行业是最大的两个雇主行业，运输和橡胶行业集中在美国的东北象限，而大多数有纺织、服装、烟草和家具制造业的县位于南部。其他行业有不同的分布模式。产业集中的县往往更具城市特征，且收入和教育水平更高。这些关于工业县的地图及相关人口数据，可能会成为展示癌症和其他疾病死亡率模式的县级地图的有用补充。尽管存在明显局限性，但直观的模式和相关分析可能有助于生成和形成关于职业性疾病的假设。
