advances research on fertility, mortality, family, migration, methods, policy, and beyond, yet it lacks a recent, rigorous review. We examine all papers published between 1947 and 2020 ( = 1,901) and their authors, using natural language processing, social network analysis, and mixed methods that combine unsupervised machine learning with qualitative coding. After providing a brief history, we map the evolution in authorship and papers towards shorter, multi-authored papers, also finding that females comprise 33.5 per cent of authorship across the period under study, with varied sex ratios across topics. Most papers examine fertility, mortality, and family, studying groups and change, but topics vary over time. Children are rarely studied, and research on women focuses on family planning, fertility decline, and unions, whereas key domains for research on men are migration, historical demography (war, famine), and employment. Research on Africa and Asia focuses on family planning, with work on fertility decline concentrated on North America and Europe, consistent with theories of demographic transition. Our resulting discussion identifies future directions for demographic research.
推进生育力、死亡率、家庭、迁移、方法、政策等方面的研究，但缺乏近期的严格审查。我们使用自然语言处理、社会网络分析和混合方法（将无监督机器学习与定性编码相结合），检查了 1947 年至 2020 年期间发表的所有论文及其作者（共有 1901 篇论文）。在提供简要历史背景之后，我们绘制了作者和论文在朝向更短、多作者论文方面的演变情况，还发现，在整个研究期间，女性占作者总数的 33.5%，不同主题的性别比例也有所不同。大多数论文研究生育力、死亡率和家庭，研究群体和变化，但研究主题随时间而变化。儿童很少被研究，对女性的研究主要集中在计划生育、生育率下降和婚姻方面，而对男性的研究重点是迁移、历史人口学（战争、饥荒）和就业。关于非洲和亚洲的研究主要集中在计划生育方面，关于生育率下降的研究主要集中在北美和欧洲，这与人口转变理论一致。我们的讨论确定了人口研究的未来方向。
