However, the graphs reveal that these thousands of factories fueled the local economies, enabling families to put food on the table and send their kids to school. In some areas, like Detroit, MI, the community was largely dependent on a single factory or company. When these companies started shutting down operations after WWII, the economy collapsed in many areas and left many people unemployed and families struggling to make ends meet. Moreover, while manufacturing is skilled labor, many workers suddenly found their skills obsolete, as most other factories had also left the area. This led to a collapse in many communities' tax bases, which closed down schools, public works, and infrastructure. Many communities were abandoned altogether as their inhabitants looked for better prospects elsewhere. Let's take a look at the population changes of the area from 1969 to 2023. **Interact Below:** Use the slider, click and drag the map, and hover over the counties to analyze the information below. Which areas increased or decreased in population over time?

However, after WWII, the U.S. shifted focus from manufacturing to higher-paying industries and outsourced manufacturing to foreign countries like China and Germany. This heavily impacted the working Americans and industries in this region. As companies moved or closed, they left many people without jobs and the area became impoverished with many abandoned factories across the region, which is where the rust belt name originated.","pinned":false,"hidden":false,"mode":"md","author":"$undefined","summary":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"","database":"$undefined"},{"id":448,"value":"\n
