"AI skill penetration," is a metric used to measure how prevalent AI-related skills are within a specific group, such as a country or profession. It's calculated by analyzing the frequency of AI skills listed in the LinkedIn profiles of members within that group. For example, if many engineers on LinkedIn have AI skills listed on their profiles, that profession would have a high AI skill penetration rate. From 2015 to 2023, India, the United States, and Germany demonstrated the highest rates of AI skill penetration. Notably, the US rate was 2.2 times greater than the global average, indicating a strong adoption of AI skills across various occupations in the country.
