From the time that humans first walked the earth, the majority of them have tended to live at close quarters to each other. That is why there are ruins of ancient cities scattered around the globe.
Today, most people live in urban communities, with only a tiny minority choosing to live in relative isolation. Arguably, most of those who live remotely because of their work (e.g. farmers) would also choose urban living otherwise. There have to be good reasons why people choose to do this.
Nothing can beat the convenience of living in a location where all essential amenities are reasonably close by. No matter how well organized we may be, there will always be occasions when we need to buy something urgently. Most urban dwellers will be able to get almost everything they want within reasonable walking distance, or a short car ride, from their homes.
People tend to feel safer living in larger communities, although that sense of security may be misplaced. While many people may shudder at the idea of living in an isolated home for fear of being an easy target for criminals, the reality is that most crimes occur in built-up areas. Nevertheless, if people in cities or big towns take reasonable precautions, they can greatly reduce the risks of having anything bad happen to them.
The range of choices people get in urban areas is a huge positive factor for living there. Being able to choose where to buy things means not having to put up with rude or inefficient staff. Having a choice of restaurants, shows or other entertainment venues simply makes life less boring.
Value for money
Retailers and service providers in urban environments face stiff competition from other businesses targeting the same marketplace. This tends to keep prices down and service levels up. For example, a recent survey of real estate prices in Scottsdale AZ showed remarkably good value for an urban style apartment for rent.
Are there any negative aspects to urban living?
There are certainly problems associated with large, densely populated urban areas. As cities expand, they tend to destroy fertile land. However, modern planning can help to offset this type of destruction. Secondly, there is no way to establish whether smaller, scattered communities would have a less negative impact. The article here discusses the arguments against urban development.
It would take a sea change in people's mentality to move away from urban environments. Therefore, improving them rather than replacing them is the way forward.
