Combining information from the 1970, 1980, and 1990 censuses of the population with African-American homicide offending data in the United States for the period 1976-1994, this research examines, empirically, the relative efficacy of two powerful explanatory schemes: One proposed by Wilson suggesting that the most important determinant of the relationship between race and crime is the concentration of African-Americans in structurally disorganized communities. The competing theory, proposed by Massey et al., argues that the interaction of racial residential segregation and poverty is more relevant in causing accelerating rates of African-American homicide and victimization. The analytic method for the research is hierarchical linear growth curve analysis. Data on rates of African-American homicide offending will be nested within counties over the period 1976-1994. The Level-1 model estimates the changes in African-American homicide offending rates within each county, over time. The parameters of these trajectories (the intercept, slope, and acceleration of the trend lines) describe the nature of change in the homicide offending rates. The Level-2 model estimates differences between counties in these trends. The importance of the research lies in the promise of increased understanding of the forces that foster urban violence, the leading cause of death among young black males.

结合1970年、1980年和1990年美国人口普查的信息和1976-1994年间美国非裔美国人杀人犯罪的数据，这项研究实证地检验了两种强有力的解释方案的相对有效性：威尔逊提出的一种方案认为，种族和犯罪之间关系的最重要决定因素是非洲裔美国人集中在结构混乱的社区。由Massey等人提出的竞争理论认为，种族居住隔离和贫困的相互作用在导致非裔美国人被杀和受害的速度加快方面更相关。研究的分析方法是层次线性增长曲线分析。1976年至1994年期间，关于非洲裔美国人凶杀案犯罪率的数据将嵌套在县内。1级模型估计了随着时间的推移，每个县内非裔美国人凶杀案犯罪率的变化。这些轨迹的参数(趋势线的截距、斜率和加速)描述了凶杀案犯罪率变化的性质。2级模型估计了县与县之间在这些趋势上的差异。这项研究的重要性在于有望增进对助长城市暴力的力量的了解，城市暴力是年轻黑人男性死亡的主要原因。
