人口统计学特征（demographic characteristics）指用于描述特定群体或人口结构的数据指标，通常用于分析社会、经济或市场趋势。其核心要素包括以下方面：
年龄与性别分布
年龄结构反映人口中不同年龄段的占比，例如青少年、劳动年龄人口与老年群体的比例。性别比例则衡量男性与女性的人口平衡，常影响医疗资源分配或消费市场策略（来源：美国人口普查局，https://www.census.gov/topics/population.html）。
收入水平与教育程度
收入数据揭示经济分层，如高收入家庭与低收入群体的消费能力差异；教育程度指标（如本科以上学历占比）则关联就业结构和社会创新能力（来源：皮尤研究中心，https://www.pewresearch.org/）。
婚姻状况与家庭规模
包括未婚、已婚、离异等状态的比例，以及每户平均人口数。此类数据对住房政策、保险产品设计等领域具有参考价值（来源：联合国人口司，https://www.un.org/development/desa/pd/）。
