Digital nomads are employees or owners of companies whose nature of work allows them to work from anywhere.
These people have been around since the advent of laptops.

With the Covid-19 pandemic, the need to work from home has grown dramatically. Specifically, from 2019 to 2020 the percentage of these people increased by 49%.

Many of them prefer to go and live in countries that have favorable conditions for their work, low taxes and where life is cheaper. Another advantage is the freedom to travel. The countries that favor this work are Estonia, Mauritius, Bermuda and Barbados.

The professions that have such a nature are the consultants of various subjects such as business, health, relationships, etc. but also those directly related to the use of computers.
