A factor estimation system (1) estimates factors of the risk of falling which indicates the possibility of a subject being measured (50) falling, the system (1) comprising: a calculation unit (21) that acquires body motion data which indicates body motion of the subject being measured (50) during walking and calculates two or more walking parameters of the subject being measured (50) on the basis of the acquired body motion data; and a factor analysis unit (23) that estimates, on the basis of the two or more walking parameters, one or more main components which are included in the factors of the risk of falling of the subject being measured (50) and are based on the two or more walking parameters, and outputs the estimation result. 原因推断系统(1)是推断表示被测量者(50)的跌倒的可能性的跌倒风险的原因的原因推断系统，具备：计算部(21)，取得表示被测量者(50)的步行时的身体运动的身体运动数据，基于所取得的身体运动数据，计算被测量者(50)的2个以上的步行参数；以及原因分析部(23)，基于2个以上的步行参数，推断被测量者(50)的跌倒风险的原因中包含的、基于2个以上的步行参数的1个以上的主成分，输出推断结果。
