Rent burden is a situation when a renter-occupied household spends a sizable portion of its income on housing costs. Using census tracts as the scale of analysis, this article examines rent burden determinants in Shelby and Davidson counties, the two largest of Tennessee. These counties differ substantially in terms of their housing markets, demographics, and the state of their economy. Mapping reveals distinct spatial patterns of rent burden and its geographic extent. Correlations and spatial regression analyses suggest that in both counties, a lack of access to an automobile, crowded living, and the presence of children in households similarly associate with higher rent burden. In contrast, educational attainment, race, and a lack of medical insurance do not demonstrate such consensus. Compared to Davidson County, race is a less crucial predictor of rent burden in Shelby County, likely due to its predominantly African American composition across different income groups. Besides, the positive effect of education is more pronounced in Shelby County. Results indicate that rent burden tends to be more of a socioeconomic class issue in Shelby County, whereas it is not as strongly associated with the socially disadvantaged in Davidson County.

田纳西州戴维森县和谢尔比县冷热住房市场的租金负担决定因素

租金负担是指租房住的家庭将其收入的很大一部分用于住房成本的情况。本文使用人口普查区作为分析尺度，研究了田纳西州最大的两个县谢尔比县和戴维森县的租金负担决定因素。这些县在住房市场、人口统计和经济状况方面存在很大差异。绘图揭示了租金负担及其地理范围的不同空间模式。相关性和空间回归分析表明，在这两个县，缺乏汽车、拥挤的生活以及家庭中有儿童同样与较高的租金负担相关。相比之下，教育程度、种族和缺乏医疗保险并没有表现出这种共识。与戴维森县相比，种族是谢尔比县租金负担的一个不太重要的预测因素，可能是由于其主要是非裔美国人在不同收入群体中的构成。此外，教育的积极作用在谢尔比县更为明显。结果表明，在谢尔比县，租金负担更像是一个社会经济阶层问题，而在戴维森县，它与社会弱势群体的相关性并不强。
