为了更好地理解非大都市县宽带与工作/收入之间的关系，本研究使用联邦通信委员会和国家宽带地图的最新数据进行了空间和一阶差分回归。在控制了年龄、种族、受教育程度、交通基础设施和自然设施等一系列潜在影响变量后，分析了农村地区宽带采用/可用性与工作/收入之间的关系。使用2011年数据的空间误差模型的结果表明，非城域县的高宽带普及率与这些县的企业数量和员工总数呈正相关。第一差分回归使用2008年和2011年的数据表明，宽带采用水平的提高与非都会县家庭收入中位数和非农业业主比例的增加有关。有趣的是，在这段时间内，仅仅获得宽带可用性（而不是采用率）的增加，对工作或收入都没有统计上的影响。
In order to better understand the association between broadband and jobs/income in non-metropolitan counties, this study conducts spatial and first-differenced regressions using recent data from the Federal Communications Commission and the National Broadband Map. The relationships between broadband adoption/availability and jobs/income in rural areas are analyzed after controlling for a host of potentially influential variables such as age, race, educational attainment, transportation infrastructure, and the presence of natural amenities. Results from spatial error models using 2011 data provide evidence that high levels of broadband adoption in non-metro counties are positively related to the number of firms and total employees in those counties. The first-differenced regressions use data from 2008 and 2011 to suggest that increases in broadband adoption levels are associated with increases in median household income and the percentage of non-farm proprietors in non-metro counties. Interestingly, simply obtaining increases in broadband availability (not adoption) over this time has no statistical impact on either jobs or income.
