人口統計學特征（demographic characteristics）指用于描述特定群體或人口結構的數據指标，通常用于分析社會、經濟或市場趨勢。其核心要素包括以下方面：
年齡與性别分布
年齡結構反映人口中不同年齡段的占比，例如青少年、勞動年齡人口與老年群體的比例。性别比例則衡量男性與女性的人口平衡，常影響醫療資源分配或消費市場策略（來源：美國人口普查局，https://www.census.gov/topics/population.html）。
收入水平與教育程度
收入數據揭示經濟分層，如高收入家庭與低收入群體的消費能力差異；教育程度指标（如本科以上學曆占比）則關聯就業結構和社會創新能力（來源：皮尤研究中心，https://www.pewresearch.org/）。
婚姻狀況與家庭規模
包括未婚、已婚、離異等狀态的比例，以及每戶平均人口數。此類數據對住房政策、保險産品設計等領域具有參考價值（來源：聯合國人口司，https://www.un.org/development/desa/pd/）。
種族與文化背景
反映社會多元性，例如不同族裔的語言使用習慣或宗教分布。政府機構常基于此制定反歧視政策或文化保護措施（來源：世界衛生組織全球健康觀察站，https://www.who.int/data/gho）。
