What is an effect of high population density in urban areas?

High population density in urban areas leads to increased demand for housing and infrastructure because a larger number of people inhabit a small geographical area. This concentration of residents places pressure on existing housing, often resulting in higher rents and property prices as more individuals compete for limited living spaces. Additionally, the need for supporting infrastructure—such as roads, schools, public transport, and healthcare facilities—increases significantly to cater to the growing population. As more people live and work in these areas, urban planners and governments must respond by investing in and expanding resources to meet these demands. Consequently, urban areas with high population densities must continually adapt and grow their housing and infrastructure to improve living conditions and accommodate the needs of their residents.
