For clarity, the number of U.S mobile users compares to the population of New York multiplied by 32. If you take together Canada, the USA, Russia, Mexico, Brasil, Argentina, Japan, Turkey, Germany, Italy, France, Spain, and Great Britain, you will receive the same total number of users as in China and India.
In 2020 alone, mobile device manufacturers sold about 1.59 billion smartphones. If someone put all those devices in a line, it would encircle the Earth five and a half times!
Mobile users make up the largest portion of your product or services consumers. If you wish to improve your website conversion rates and decrease customer churn, you can't do without adapting websites for mobile devices.
