A growing trend of people living alone more frequently has been observed in many countries. This could be due to urbanization as most of the jobs are in the big cities and they expect to work from the location. I believe this is positive development.
Most of the population in many countries lives in tier 2 cities, towns and villages. People living alone could be due to urbanization as alot of the jobs tends to be in the big cities and expect employees to work from office which leads to people migrating from smaller cities to bigger ones. Generally, these jobs pay high salaries which makes people more competitive. As a result, people focus on upskilling which requires high concentration and less disurbing environment and prefer to live alone which provides these benefits.
Living along helps people build personality as they must be independent, self-relieant and capable of handling their day-to-day acitivites by themselves. They get better exposure of the world as they often interact with new people. In some cases living alone could be better of their mental health as well, because some habits of the family members or the relationship with them is not positive.
However, there are potential drawbacks of living alone. For instance, less social interaction may cause depression. Also it becomes difficult when they need someone’s help in case of emergency-sickness, for example.
In conclusion, eventhough there are disadvantages of living along, I see it as a positive development since primary motive behind it is growth and to be successful in life.
