一个详细的人口统计学分析是由威斯康星州地区灵长类动物研究中心恒河猴殖民地的生命统计记录在20年的时间。所使用的技术是基于人口统计学和流行病学方法开发的人群，这提供了在圈养灵长类动物的殖民地进行标准化测量的潜力。一个基于1,086例死亡的生命表显示，老年人的存活率异常高，这可能是由于为了繁殖目的而保留特别健壮的动物的趋势。在研究期间，2，194只动物被移除用于销售或研究。各年龄段的去除率相对一致。根据第二个十年期间出生的1 616名婴儿计算的特定年龄组生育率显示，从大约2岁到12岁，出生率相对迅速增加，生育高峰持续到大约20岁。生命事件具有明显的季节性，4月和5月是出生高峰。对稳定年龄结构（不包括迁移）的分析表明，内在增长率为6.3%。随着去除率的增加，增长率下降到-0.3%。虽然这些方法的使用可能只需要在圈养群体记录中发现的详细程度，但对圈养群体的分析可以提供与野生灵长类动物人口统计学相关的信息。
A detailed demographic analysis was made of the Wisconsin Regional Primate Research Center rhesus colony from vital statistics recorded over a 20-year period. Techniques used were based on demographic and epidemiological methods developed for human populations, which provide the potential for making standardized measurements within captive primate colonies. A life table based on 1,086 deaths showed an abnormally high survivorship at the older ages, probably caused by a tendency to retain especially robust animals for breeding purposes. During the period of study, 2,194 animals were removed for sale or research. Removal rates were relatively uniform across ages. Age-specific fertility rates based on 1,616 births occurring during the second decade showed a relatively rapid increase in births from about age 2 through age 12, with peak fertility persisting until about age 20. Vital events showed significant seasonality, with a birth peak in April and May. Analysis of the stable age structure (excluding removal) showed an intrinsic growth rate of 6.3%. With removal rates added, the growth rate dropped to -0.3%. Although the use of these methods is probably warranted only by the level of detail found in captive colony records, analysis of captive colonies can provide information relevant to the demography of wild primates.
