evidence: Unemployment leads to several adverse effects including increased mental health issues, crime rates, and economic challenges like inflation. [...] When evaluating the unemployment rates of countries in comparison with one another, it is vital to keep in mind that it is not always an apples-to-apples comparison. For starters, not every country has the same definition of unemployment—for instance, some countries say that if a person is able to work but not currently employed, that person is unemployed. But other countries only consider a person unemployed if they are actively seeking work. People who are not working and not looking for work are not considered unemployed. Obviously, these different definitions will have an impact on the unemployment rates posted by those countries. [...] Unemployment has many adverse effects, including: increased depression and other mental health problems, increased crime rates, overall lower economic productivity and consumption, lower rates of volunteerism, and erosion of skills. Surprisingly, exceptionally low unemployment can also create economic challenges, such as excessive inflation (when everyone is employed and has money to spend, demand for products can outstrip supply, which causes a rise in prices). This can lead to a rising cost of living, which can be particularly hard on citizens in developing and/or low-income countries.
