As of 2018, there were 19,495 incorporated cities, towns and villages in the United States – and out of those, 14,768 have populations below 5,000. Only ten places have populations above 1 million and none are above 10 million. 310 cities are considered at least medium cities with populations of 100,000 or more. The largest city in the U.S. — part of the Northeast megalopolis — is New York City, with a population of 8.5 million people. New York City has five boroughs: Manhattan, the Bronx, Brooklyn, Queens, and Staten Island. New York City is also the largest metropolitan area in the world by urban area (4,585 square miles) and by population by both Metro Statistical Area (20.3 million) and combined statistical area (23.7 million).
Population growth in any area can have many effects, but one of the most notable effects of dense population on industries is the heightened demand for goods and services. In densely populated cities, consumer markets are larger and more diverse, presenting businesses with lucrative opportunities to cater to the needs and preferences of urban dwellers. For example, companies like Walmart Inc. (NYSE:WMT), Target Corporation (NYSE:TGT), and Costco Wholesale Corporation (NASDAQ:COST) strategically establish their stores in urban centers to capitalize on dense population concentrations and cater to the needs of urban shoppers.
According to their financial reports, Walmart Inc. (NYSE:WMT)’s total revenue for the fiscal year 2023 was $648.13 billion, representing an increase of about 6.03% compared to the previous year. Whereas, Costco Wholesale Corporation (NASDAQ:COST)’s revenue for the fiscal year ending September 3, 2023, was $242.3 billion, representing a 6.7% YoY growth. It is important to note that for both companies, a huge chunk of their revenue comes from New York city. Therefore, from retail stores and hospitality to healthcare and entertainment, industries must adapt and innovate to meet the demands of densely populated urban markets, driving competition and fostering dynamic economic ecosystems.
Moreover, dense population centers often serve as hubs of innovation and entrepreneurship, fueled by the concentration of talent, resources, and investment opportunities. Tech havens like Silicon Valley in California and the burgeoning startup scene in cities like Austin, Texas, thrive amidst dense urban landscapes, harnessing the creative energy and collaborative spirit of densely populated environments to drive technological advancements and economic growth. However, alongside opportunities and diversity, challenges come in the view too. As populations swell and urban boundaries expand, issues such as housing affordability, transportation congestion, and unstable living conditions, impacting the overall way of life for those residing in densely populated cities.
Overcrowding is more prevalent in densely populated cities, with a higher percentage of households living in overcrowded conditions, defined as having more than one person per room, compared to less densely populated areas. Therefore, high population density is associated with increased housing instability. In an article on housing accessibility in densifying cities, it has been identified that renters in densely populated areas are more likely to experience eviction and housing displacement due to rising rents and limited affordable housing options. It is also said that in cities with high population density, housing costs tend to be significantly higher; For example, in San Francisco, the median rent for a one-bedroom apartment is around $3,400 per month, compared to $1,200 in a less densely populated city like Indianapolis. This hike in the rents impacts the overall purchasing power of the residents living in densely populated cities because a significant chunk of their income is spent paying for housing.
Cities with high population density tend to have the worst traffic congestion; Los Angeles and New York City consistently rank among the top cities in the United States for traffic congestion, with commuters spending an average of 100 hours or more stuck in traffic congestion each year. Poor traffic conditions impact people and cities in more ways than one.
A study published on ‘Traffic Congestion’s Economic Impacts’, found that traffic congestion in densely populated areas leads to significant economic costs, including lost productivity, increased fuel consumption, and higher vehicle maintenance expenses. It is also estimated that traffic congestions costs the economy over $160 billion annually, which is a significant loss for any economy.
