年齡跨越和年齡結年齡跨越和年齡結 年齡跨越和年齡結年齡跨越是被調查人夸大或縮小自己的真實年齡的行為。造成年齡跨越的原因是極為復雜的，它既可能出于被調查人的年齡概念不清，也可能出于蓄意錯報。如在尊崇老年人的社會中，人們有可能習慣夸大年齡。有些和本民族獨特的計算年齡方法有關，如中國使用的陰歷歷法是將出生的嬰兒規定為1歲。 年齡結也叫年齡堆積。以某一數字結尾的年齡或某一年齡的人口遠遠超過其他數字結尾年齡或其附近年齡的人口的一種現象。造成年齡堆積現象的原因是所謂“數字偏好”，即被調查人報告年齡時傾向于以某一數字結尾。數字偏好往往出于年齡概念不清。很多社會中，人們對自己年齡有一定的認識，但這種認識是極不準確的，它可能基于生理外觀的變化，或家庭生命周期的演屯，甚至可能和所在區域的自然景觀變化持正相關聯系。這種模粕，勝使被調查人在報告自己年齡時選擇某一最熟悉的數字結尾。。交5是最自然的選擇。
