One problem is increased competition for limited resources such as housing and jobs. As more people migrate from rural areas to urban centers, the demand for housing and employment opportunities grows, leading to higher competition and potentially increased housing costs. This can put strain on existing urban residents and make it harder for newcomers to find affordable housing and secure jobs. Another issue caused by rural-to-urban migration is increased pressure on urban infrastructure and services. The influx of migrants can strain existing systems such as transportation, healthcare, and education, leading to overcrowding and potential service shortages. This can impact both old residents who may experience deteriorating quality of services, and new residents who may struggle to access necessary amenities
