Historical demographers have generally agreed on two interrelated features of the urban populations in early-modern Germany. First in accordance with the law of natural decrease, extremely high mortality rates in cities (urban areas with more than 10,000 inhabitants) meant that their populations could not be sustained by reproduction alone. Population density, inadequate sanitary conditions, and poor housing made cities too vulnerable to disease and death. Second, when city populations did increase, it was as a result of in-migration sufficient to overcome the population losses caused by the high mortality. But because the parish registers of urban communities with fewer than 10.000 inhabitants show that the annual number of births usually equaled or exceeded that of deaths, historical demographers assume that the law of natural decrease did not apply to small towns.

Consider each of the choices separately and select all that apply.

It can be inferred that historical demographers generally believe which of the following about communities of fewer than 10,000 people in early-modern Germany?

mortality rates were lower than those in cities of over 10,000 inhabitants. in-migrations were not a signifificant factor in population trends. population levels remained quite stable for extended periods.

本题定位及解读题干关键词：fewer than 10,000关键词类型：细节需要阅读的句子01(本句)：“But because the parish registers of urban communities with fewer than 10,000 inhabitants show that the annual number of births usually equaled or exceeded that of death, historical demographers assume that the law of natural decrease did not apply to small towns."含义：但由于人口少于一万的城市的教区登记册显示，每年的出生人数通常等于或超过死亡人数，历史人口统计学家认为自然减少的法则不适用于小城镇。需要阅读的句子02(前句)：“First, in accordance with the law of natural decrease, extremely high mortality rates in cities meant that their populations could not be sustained by reproduction alone.”含义：根据自然减少法则，城市死亡率很高，意味着生育不能够维持城市人口。选项分析正确选项A：【句子02】指出自然减少法则体现出生率小于死亡率，【句子01】指出人口10,000以下的城镇不适用自然减少法则，所以这些小城镇出生率大于或等于死亡率，因此比大城镇的死亡率要低。错误选项BC：原文没有提到人口迁徙对人口一万以下的城镇的作用。做题笔记
