Intra-institutional variables examined included average jail stay, person-years at risk, arraigned versus convicted status of inmates, overcrowding, and staffing patterns. Extra-institutional variables included corrections expenditures, region, and court orders for inmate grievances. In 1977, the three extra-institutional variables were related to both suicides and natural deaths, but only person-years at risk contributed significantly. Variance in natural deaths also was affected by staffing level and statewide average jail stay. By 1983, the person-years at risk variable accounted for virtually all the variance in natural deaths and suicides, with marginal contributions from region and court intervention (for suicides only). 6 cases and 57 references.
