There has been an increasing share of older workers in America’s workforce as Baby Boomers continue to age into this group. This raises questions about what their local labor markets look like in space and how they differ from Millennials and Generation Xers who are also active in today’s workforce. However, even though significant generational (or age) differences in commuting distance have been well documented, questions about generational disparities in local labor market geographies have not been investigated. Although several definitions of market areas exist, they were delineated using all commuting trips made by all workers in a region and thus may not be representative of subgroups of workers. The aim of this research is to delineate generation-specific local labor market areas and compare how they differ from one another. Using flow visualizations and three employment self-containment indices applied to a Longitudinal Employer-Household Dynamics dataset of Florida, this research finds that the core-based statistical areas, a popular definition of local labor market areas, understate the true market geographies across generational cohorts. It then delineates generation-specific market areas using a popular community detection method and compares their geographies using the self-containment indices. Results demonstrate largely consistent market geographies across the three generational cohorts in most regions in Florida. Most of these consistent market areas encompass two or more metros, indicating the emergence of functional megaregions centering on major metropolitan hubs. Substantial generational differences in market geographies do exist and concentrate in regions appealing to seniors along the Gulf of Mexico.

随着婴儿潮一代继续进入这一群体，美国劳动力中老年工人的比例越来越高。这引发了关于他们当地劳动力市场在太空中的样子以及他们与同样活跃于当今劳动力市场的千禧一代和 X 一代有何不同的问题。然而，尽管通勤距离的显着代际（或年龄）差异已得到充分证明，但尚未调查有关当地劳动力市场地理代际差异的问题。尽管存在多种市场区域定义，但它们是使用一个区域内所有工人的所有通勤旅行来界定的，因此可能不代表工人的子群体。本研究的目的是描绘特定世代的当地劳动力市场区域，并比较它们之间的差异。使用流动可视化和三个就业自足指数应用于佛罗里达州的纵向雇主-家庭动态数据集，本研究发现，基于核心的统计区域（当地劳动力市场区域的流行定义）低估了跨代群体的真实市场地理. 然后，它使用流行的社区检测方法描绘特定世代的市场区域，并使用自包含指数比较它们的地理区域。结果表明，佛罗里达州大部分地区的三个世代群体的市场地理分布基本一致。这些一致的市场区域中的大多数都包含两个或更多的地铁，这表明以主要大都市枢纽为中心的功能性特大区域的出现。
