The revelation of how many office functions can be done at home is opening up the option for many to travel the world in between workdays, a lifestyle known as digital nomadism.

Digital nomads are growing in number as technology advances both in terms of the software they use to work, and in terms of the countries they visit. The digital nomad brand and business is coveted, and recently the Portuguese government turned an entire community on the beautiful island of Madeira into a "digital nomad village."

Recently, an Italian firm conducted a broad-scale analysis of 75 major cities around the world, and ranked them for a variety of factors pertaining to digital nomading—such as average Wi-Fi speed, average rent cost, security, burden of government, weather and air quality, and more.
