Sex ratios at birth are known to change during wars or shortly after. This study investigated changes in sex ratios during the civil war that occurred in Tajikistan after the dismantling of the Soviet Union. This civil war was particularly bloody and long lasting, and had many demographic consequences. According to vital registration data, some 27,000 persons died in excess of previous trends during the civil war period (1992-1997), and total mortality was sometimes estimated to be three times higher by independent observers. Birth rates dropped markedly during the war, and sex ratios at birth increased significantly from 104.6 before the war to 106.9 during the war, to return to baseline values afterwards. The change in sex ratio is investigated according to demographic evidence (migration, delayed marriage, spouse separation), substantiated with qualitative evidence (difficulties with food supply), and compared with patterns found in Europe during World War II, as well as with recent wars in the Middle East.
已知出生性别比例会在战争期间或战后不久发生变化。本研究调查了苏联解体后塔吉克斯坦内战期间出生性别比例的变化。这场内战异常血腥且旷日持久,对人口产生了诸多影响。根据人口登记数据,内战期间(1992-1997 年),超过以往趋势的死亡人数约为 2.7 万,独立观察人士估计,战争期间的总死亡率有时甚至是正常时期的三倍。战争期间出生率显著下降,出生性别比例从战前的 104.6 显著上升至战时的 106.9,战后又恢复到基线水平。本研究根据人口统计证据(移民、延迟结婚、配偶分居),结合定性证据(食物供应困难),对性别比例的变化进行了调查,并与第二次世界大战期间欧洲以及中东近期战争中的模式进行了比较。
