云南玉溪地区人口的性比

对云南玉溪地区1982年人口普查时的性比(男:女100)进行了分析,发现:(1)玉溪地区总人口的性比(99.22)比全国的(106.3)低,0—4岁与5—9岁儿童的性比(103.45与102.9)也比全国的(107.15与106.24)低。(2)傣族的性比特别低,其0—14岁儿童的性比为98.54;回族的性比也较低,其0—14岁儿童的性比为101.22;汉族0—14岁儿童性比则为104.16。(3)“大跃进”与“国民经济暂时困难”时期出生的人(20—24岁)性比特别低,仅为92.30,而且按民族,县,及城、乡分别统计时均有同样趋势。这一情况在全国人口性比统计中也得到证实。作者估计,这可能是当时自然流产增多造成的。(4)玉溪地区解放以来总人口性比不断增高,1953年为88.70,1964年为94.94,1982年则为99.22。(5)城镇人口的性比(156.48)比农村的(95.86)高得多,这与全国各地区相同。

SEX RATIO IN YUXI DISTRICT, YUNNAN PROVINCE

The sex ratio (male: female 100) in Yuxi District, Yunnan Province was analysed by using the data of the last national census in 1982. The following results were ob-tained: 1. The sex ratio of total population in Yuxi District (99.22) was lower than that of the whole country (106.3), even the sex ratio in the age group of 0-4 and 5-9 years (103.45 and 102.90, respectively) were also lower than those of the whole country (107.15 and 106.24, respectively). 2. The sex ratio of Dai ethnic group is unusually low, that of 0-14 years old being 98.54. The sex ratio of Hui ethnic group is also low, with a value of 101.22 for 0-14 years age group, while that for Han ethnic group in the same district is 104.16. 3. The persons born in the period of "Great Leap Forward" and "Temporal Dif-ficulties in National Economy" (aged 20-24 years) have a especially low sex ratio (92.30), which is the same when calculated for different ethnic groups, or different counties, OP urban and rural populations separately, and also for the whole country. It is suggested that the increase of spontaneous abortions might be the cause. 4. The sex ratio of the total population in Yuxi District has been ever increasing steadily since the liberation, from 88.70 in 1953 to 94.94 in 1964,, and to 99.22 in 1982. 5.
