Estimates of the occurrence of new cases, frequency of existing cases, and economic costs of injury to the head or spinal cord are presented for the population of the contiguous United States for the year 1974. Estimates for subpopulations defined by demographic variables (age, race, sex and region in which injury occurred) are also presented, as well as related estimates on cause of injury, length of stay in hospital, and mortality. All estimates are from the National head and Spinal Cord Injury Survey and should be interpreted on the basis of how the study was conducted.
本文给出了1974年美国本土人口头部或脊髓损伤的新发病例数、现患病例数以及经济成本的估计值。还给出了按人口统计学变量（年龄、种族、性别以及损伤发生地区）定义的亚人群的估计值，以及关于损伤原因、住院时长和死亡率的相关估计值。所有估计值均来自全国头部和脊髓损伤调查，应根据该研究的开展方式进行解读。
