In this post, we’ll examine some numbers on stress in the United States. There are many sources of stress, and the impact of the same source of stress always depends on the person affected. The chart below shows the statistics on the share of Americans who felt their personal safety was a very or somewhat significant source of stress from 2012 to 2017. In 2012, 29 percent of respondents stated they felt stressed about their personal safety. The number grew slightly in the next year, reaching 30 percent.

In 2014, the share of American citizens who felt stressed about their personal safety amounted to 23 percent. In 2015 and 2016, the numbers reached 30 percent and 29 percent respectively. This amount increased in 2017, reaching its peak of 34 percent of respondents who felt stressed about their personal safety.

One in every 20 Americans (among those in the labor force) has more than one job. But that number alone doesn’t tell us the whole story.

The fact is, this number is decreasing: While the exact percentage was 5.6 percent in 2000, it’s now down to 4.7 percent. The decline primarily took place before 2010, and the numbers haven’t changed much since then.
