The swimming ability of 4128 Queensland school children was studied. The median age for swimming 10 metres is 6.5 years. Ninety-five percent of children are able to swim by 11 years of age. Cumulative frequency curves, by age, are presented for the ability to swim 10 and 50 metres: the latter distance is of relevance in boating accidents. Twenty percent fewer children from lower socioeconomic levels are able to swim. Water safety training is as important as swimming lessons.
对4128名昆士兰学童的游泳能力进行了研究。游10米的年龄中位数为6.5岁。95%的儿童在11岁时能够游泳。按年龄给出了游10米和50米能力的累积频率曲线：后一距离在划船事故中具有相关性。社会经济水平较低的儿童中能够游泳的人数要少20%。水上安全培训与游泳课程同样重要。
