题目内容
【题目】读“甲、乙两地人口的抽样调查表(每10 000人中各年龄段人数及死亡率统计)”,据此回答下列各题。
年龄 | 0~14 | 15~60岁 | 60岁以上 | 总计 | |
甲 | 人口数 | 2 000 | 6 500 | 1 500 | 10 000 |
死亡率(%) | 0.6 | 0.6 | 2.5 | 3.7 | |
乙 | 人口数 | 3 500 | 6 000 | 500 | 10 000 |
死亡率(%) | 0.75 | 0.7 | 2.2 | 3.65 | |
【1】下列说法正确的是
①决定人口自然增长率的是出生率与死亡率
②人口出生率由人口基数决定,基数大,出生率就高
③死亡率由人口数量决定,人口越多,死亡率越高
④人口增长数量与人口基数有重要关系,一般人口基数越大,增长数量越大
A. ①② B. ③④ C. ①④ D. ②③
【2】下列说法与表格内容相符的是
①乙地人口表示发展中国家,甲地人口表示发达国家
②各年龄段死亡率甲小于乙,因此死亡总人口数也是甲小于乙
③发展中国家的死亡率高于发达国家
④甲地人口死亡率偏高一些,主要原因是甲组老年人口比例高
A. ①② B. ①④ C. ③④ D. ②③
【答案】
【1】C
【2】B
【解析】试题分析:
【1】人口的自然增长率等于人口的出生率减轻人口的死亡率;因人口增长的数量等于人口基数乘以人口自然增长率,所以人口的增长数量与人口基数有重要关系,一般人口基数越大,增长数量越大;而人口的出生率等于人口出生数量与人口基数的比值,所以人口出生率由人口基数决定,基数大,出生率就低;死亡率由人口数量决定,人口越多,死亡率越低。故选C。
【2】分析表格中数据得知,甲地0~14的人口所占比重相对较小,而60岁以上人口所占比重较大,应为发达国家;乙地0~14的人口所占比重相对较大,而60岁以上人口所占比重较小,应为发展中国家;甲地人口死亡率偏高一些,主要原因是甲组老年人口比例高;而60岁以上人口死亡率,甲大于乙;发展中国家因老年人口所占比重较小,所以死亡率低于发达国家。故选B。
