Edward Jarvis in 1850 first demonstrated that admission rates to mental hospitals decrease with increasing residential distance, a relationship known today as “Jarvis's Law.” His original data are presented, mapped, and examined by regression analysis to better understand spatial and temporal patterns of mid-19th century mental hospital utilization. Distance substantially affected admission rates to a radius of about 60 miles from the institution in Massachusetts; and there was strong distance decay in the other states examined. For all twelve states, there was a positive association between age of the hospitals and admission rates, which also decreased with increasing residential distance.

贾维斯重新审视：19 世纪中叶庇护服务区的距离衰减

爱德华·贾维斯 (Edward Jarvis) 在 1850 年首次证明，精神病院的入院率随着居住距离的增加而降低，这种关系今天被称为“贾维斯定律”。他的原始数据通过回归分析呈现、映射和检查，以更好地了解 19 世纪中叶精神病院使用的空间和时间模式。距离在马萨诸塞州的机构大约 60 英里的半径范围内极大地影响了录取率；并且在检查的其他状态中存在强烈的距离衰减。对于所有 12 个州，医院年龄与入院率呈正相关，并且随着居住距离的增加而下降。
