Portugal is one of the 5 safest countries in the world, according to the Global Peace Index 2021, just behind Iceland, New Zealand and Denmark. In other words, it is second among the countries of the European Union. The fact that Portugal is considered one of the safest countries in the world is an asset for the quality of life of the Portuguese and a competitive advantage compared to other countries. The security issue is far from being a strictly police issue. Today, security is a decisive factor in attracting investment, in attracting tourists, in order to strengthen the country’s overall image. Portugal recorded, in 2020, the lowest crime indicators since the existence of the current registration model. And it is important to remember that this result was achieved during a pandemic period (COVID-19), which in many countries has contributed to the increase in conflicts and the increase in certain forms of crime. In this 15th edition of the Index, which covers 99.7% of the world’s population, it is concluded that the global level of peace has continued to deteriorate, in a world where conflicts and crises have emerged in the last decade have started to wane and are being replaced by a new wave of tension and uncertainty in the wake of the COVID-19 pandemic – as well as growing tensions between the great powers. The important security measures taken by Portugal in recent years have led to a reduction in crime and, as a result, the gradual and consolidated rise in this classification. It should be noted that in 2014, Portugal occupied 18th place after having climbed the rankings in recent years.
