The concept of job security has changed dramatically in recent decades, and it is now common for individuals to hold several jobs throughout their working life. In the United States, the average number of jobs someone has in their lifetime varies depending on the study, but the general trend is that people are changing jobs more frequently than in the past.

According to the Bureau of Labor Statistics, the average worker in the United States held approximately 12 jobs between the ages of 18 and 52. This figure is based on a longitudinal study conducted between 1979 and 2016, which followed a cohort of young men and women as they entered the workforce and progressed through their careers.

Other studies have reported slightly different figures. A report by the U.S. Department of Labor found that the average worker held 10.8 jobs between the ages of 18 and 42, while a survey by LinkedIn found that Millennials expect to hold an average of 12 jobs in their lifetime.

The reasons for changing jobs are varied and include seeking better pay, more interesting work, or a better work-life balance. Some people change jobs because they are dissatisfied with their current employer or because they want to pursue a new career path.

In addition, the nature of work has changed over the years. The traditional model of working for the same company for your entire career has largely disappeared, and people are now more likely to have a series of shorter-term jobs or to work as freelancers or contractors.

The rise of the gig economy, which includes services like Uber and TaskRabbit, has also contributed to the trend of people having multiple jobs. These types of jobs are often more flexible and allow individuals to work when and where they want, but they can also be less secure and provide fewer benefits than traditional employment.

While changing jobs frequently can be a positive thing for career development, it can also have drawbacks. For example, people who change jobs frequently may have less job security, which can lead to financial instability and stress. In addition, frequent job changes can make it more difficult to establish a career path and may limit opportunities for advancement.

Another factor to consider when examining the average number of jobs someone has in their lifetime is the impact of automation and technological change. Some industries are being disrupted by new technologies, which is leading to job losses and changes in the nature of work. As a result, some workers may need to retrain or switch careers in order to stay employed.

In summary, the average number of jobs someone has in the United States varies depending on the study, but it is generally accepted that people are changing jobs more frequently than in the past. The reasons for changing jobs are varied, but often include seeking better pay, more interesting work, or a better work-life balance. The rise of the gig economy and technological change are also contributing to the trend of people having multiple jobs. While changing jobs frequently can be positive for career development, it can also have drawbacks, such as reduced job security and limited opportunities for advancement.
